2 About Seafood Watch Monterey Bay Aquarium’s Seafood Watch® program evaluates the ecological sustainability of wild-caught and farmed seafood commonly found in the United States marketplace. Seafood Watch® defines sustainable seafood as origina ng from sources, whether wild-caught or farmed, which can maintain or increase produc on in the long-term without jeopardizing the structure or func on of affected ecosystems. Seafood Watch® makes its science-based recommenda ons available to the public in the form of regional pocket guides that can be downloaded from www.seafoodwatch.org. The program’s goals are to raise awareness of important ocean conserva on issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommenda on on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this informa on against the program’s conserva on ethic to arrive at a recommenda on of “Best Choices,” “Good Alterna ves” or “Avoid.” The detailed evalua on methodology is available upon request. In producing the Seafood Reports, Seafood Watch® seeks out research published in academic, peer-reviewed journals whenever possible. Other sources of informa on include government technical publica ons, fishery management plans and suppor ng documents, and other scien fic reviews of ecological sustainability. Seafood Watch® Research Analysts also communicate regularly with ecologists, fisheries and aquaculture scien sts, and members of industry and conserva on organiza ons when evalua ng fisheries and aquaculture prac ces. Capture fisheries and aquaculture prac ces are highly dynamic; as the scien fic informa on on each species changes, Seafood Watch®’s sustainability recommenda ons and the underlying Seafood Reports will be updated to reflect these changes. Par es interested in capture fisheries, aquaculture prac ces and the sustainability of ocean ecosystems are welcome to use Seafood Reports in any way they find useful.

3 Guiding Principles Seafood Watch defines sustainable seafood as origina ng from sources, whether fished1 or farmed, that can maintain or increase produc on in the long-term without jeopardizing the structure or func on of affected ecosystems. Based on this principle, Seafood Watch had developed four sustainability criteria for evalua ng wildcatch fisheries for consumers and businesses. These criteria are: How does fishing affect the species under assessment? How does the fishing affect other, target and non-target species? How effec ve is the fishery’s management? How does the fishing affect habitats and the stability of the ecosystem?
Each criterion includes: Factors to evaluate and score Guidelines for integra ng these factors to produce a numerical score and ra ng
Once a ra ng has been assigned to each criterion, we develop an overall recommenda on. Criteria ra ngs and the overall recommenda on are color-coded to correspond to the categories on the Seafood Watch pocket guide and online guide: Best Choice/Green: Are well managed and caught in ways that cause li le harm to habitats or other wildlife. Good Alterna ve/Yellow: Buy, but be aware there are concerns with how they’re caught. Avoid/Red Take a pass on these for now. These items are overfished or caught in ways that harm other marine life or the environment.

4 Summary The following Seafood Watch report provides recommenda ons for Atlan c cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and pollock (Pollachius virens) caught in the Northwest Atlan c by U.S fishing vessels. The three species inhabit similar habitats, have similar natural ranges, and are caught in mixed fisheries using a variety of methods including bo om trawls, sink gillnets, bo om longlines, and rod and line that will be covered by this report. The fisheries that capture cod, haddock, and pollock in the Northwest Atlan c are managed by the New England Fisheries Management Council (NEFMC) under the Mul species Fishery Management Plan. Cod, haddock, and pollock have a high inherent vulnerability to fishing pressure. There are two separate stocks of cod and haddock in the U.S. Northwest Atlan c: Georges Bank and the Gulf of Maine. Cod abundances on Georges Bank and in the Gulf of Maine are in an overfished state and of high conserva on concern. Fishing pressure on both stocks by all fishing gears is too high. Haddock stocks are healthier and have fully rebuilt on Georges Bank and in the Gulf of Maine. Georges Bank haddock is fished at a sustainable level, and fishing pressure in the Gulf of Maine has reduced to sustainable levels. Pollock abundance in the Northwest Atlan c is healthy and is being fished at a sustainable level. The handline fisheries in the Northwest Atlan c are rela vely selec ve, with no species of concern caught other than the target species (typically cod). Bo om trawl fisheries in the Northwest Atlan c catch a variety of species, including commercially important fish and marine mammals. Of greatest concern in the bo om trawl fisheries for cod, haddock, and pollock is the bycatch of yellowtail flounder, which is overfished and experiencing overfishing on Georges Bank and in the Gulf of Maine. Bo om gillnet fisheries catch a variety of species, including a number of marine mammals; of greatest concern is the North Atlan c right whale, which is listed as "Endangered" by the Interna onal Union for the Conserva on of Nature (IUCN) and is being nega vely affected by fishing ac vi es in the region. Bo om longline fisheries are rela vely selec ve compared to the trawl and gillnet fisheries, but there is s ll a high level of concern regarding bycatch of skate species. Bo om trawls have a discard rate of 48% in the region, with gillnets and longlines each having a discard rate of 28%, and handline having a discard rate of 8% (most of which is undersized cod).
The NEFMC manages the groundfish fishery through a collec ve Fishery Management Plan (FMP) that covers 20 stocks from 13 species. Grouping species together allows NEFMC to manage these mixed fisheries more effec vely than if individual species FMPs were used. Because of the historical exploita on that the stocks have been exposed to, a number of stocks are depleted or in a state of rebuilding. NEFMC has recently introduced a new management system that should improve the rate of recovery of stocks. There is a considerable effort to collect data in these fisheries through logbooks and observer coverage; the data (along with fishery- independent data) guide stock assessments. NEFMC take into account the scien fic informa on provided by stock assessments on the majority of occasions; however, in some instances, total allowable catches (TACs) have been set too high in response to social and economic need. There are a number of regula ons in place that require fisheries managers to reduce the impacts of fishing ac vi es on nontarget popula ons. Repor ng of bycatch creates an incen ve for reduc on efforts while providing data for scien fic research and stock assessments. The observer program provides considerable data to aid in stock assessments of target and bycatch species. Enforcement is generally good, but enforcement of regula ons concerning the use of pingers in gillnet fisheries could be improved. The majority of the groundfish fishery takes place in water less than 100 m deep over sand and sand-silt habitats; gravel habitats affected by the fishery occur in waters less than 60 m deep. Habitat impacts are a moderate conserva on concern for bo om trawl fisheries, a low conserva on concern for bo om gillnet and bo om longline fisheries, and a very low concern for handline fisheries. There is a minimal level of mi ga on measures in place in the form of a number of permanent closed areas to protect essen al fish habitat from bo om trawls, and in other temporary and permanent closures that offer some protec on from all gears (but these are not designated specifically for habitat protec on and may not protect the most vulnerable of habitats). Ecosystem-based management is currently being developed for the groundfish fishery in the Northwest Atlan c and this process is expected to take a minimum of 5 years. Management of the ecosystem in this region is a moderate conserva on concern.

7 Summary Handline fisheries for cod and haddock from Georges Bank and the Gulf of Maine are considered a GOOD ALTERNATIVE, due in part to the selec ve nature of the fishing gear. Haddock and pollock caught in the Georges Bank and Gulf of Maine regions with all gears are considered a GOOD ALTERNATIVE as stocks are healthy but there are moderate to high concerns over bycatch of other species. Cod caught from Georges Bank and the Gulf of Maine using bo om trawls, bo om gillnets, and bo om longlines receive an AVOID recommenda on due to concerns of the target stock and bycatch species.
Eco-Cer fica on Informa on The US Acadian redfish, haddock and pollock o er trawl fishery was cer fied as sustainable by the Marine Stewardship Council in July 2016.
Scoring Guide Scores range from zero to five where zero indicates very poor performance and five indicates the fishing opera ons have no significant impact. Final Score = geometric mean of the four Scores (Criterion 1, Criterion 2, Criterion 3, Criterion 4). Best Choice/Green = Final Score >3.2, and no Red Criteria, and no Cri cal scores Good Alterna ve/Yellow = Final score >2.2-3.2, and neither Harvest Strategy (Factor 3.1) nor Bycatch Management Strategy (Factor 3.2) are Very High Concern2, and no more than one Red Criterion, and no Cri cal scores Avoid/Red = Final Score ≤2.2, or either Harvest Strategy (Factor 3.1) or Bycatch Management Strategy (Factor 3.2) is Very High Concern or two or more Red Criteria, or one or more Cri cal scores.
2 Because effec ve management is an essen al component of sustainable fisheries, Seafood Watch issues an Avoid recommenda on for any fishery scored as a Very High Concern for either factor under Management (Criterion 3).
8 Introduc on
Scope of the analysis and ensuing recommenda on The following Seafood Watch report provides recommenda ons for Atlan c cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and pollock (Pollachius virens) caught in the Northwest Atlan c by U.S fishing vessels. The three species are caught in mixed fisheries using a variety of methods including bo om trawls, sink gillnets, bo om longlines, and rod and line that will be covered by this report. Recommenda ons are provided for the gears that catch a significant volume of each species or offer a more sustainable op on (see Table 1).
Species Overview Atlan c cod is widely distributed throughout the North Atlan c and the Arc c Oceans. In the Northwest Atlan c, it can be found from Cape Ha eras, North Carolina to Greenland. It is found to depths of 600 m, although typically it inhabits depths of less than 200 m (Froese & Pauly 2012). Atlan c cod is an extremely important commercial species that has been targeted throughout its range for many years, making it culturally and socially significant.
Haddock is found in both the Northwest and Northeast Atlan c in water temperatures between 4°C and 10°C. In the Northwest Atlan c, it is found between Cape May, New Jersey and the Strait of Belle Isle, Newfoundland. Typically found at depths between 10 m and 200 m, it is demersal, living above rocky, sand, gravel, or shell-based seabeds and feeding on crustaceans, echinoderms, mollusks, worms, and fish (Froese & Pauly 2012). Pollock is closely related to both cod and haddock and is part of the Gadoid family of fish. It is found throughout a range similar to both cod and haddock: throughout the coastal and con nental shelf region of the North Atlan c. In the Northwest Atlan c, it ranges from Greenland to North Carolina, in both inshore and offshore areas, typically forming shoals (Froese & Pauly 2012).
The groundfish fishery in New England has been in existence for 400 years and provided the first major industry for early se lers in this region, with a number of associated businesses arising to support the fishing industry. Thus the groundfish fishery of New England is of great social and economic importance to the local communi es. Over the centuries, capture methods have changed drama cally with improvements in technology and efficiency of the fishery. As a result of the increased efficiency, overfishing occurred, resul ng in the deple on of many of the Northwest Atlan c groundfish stocks. Concerns with overfishing were raised in the early 1900s, and in the 1930s the overcapacity of the industry became evident (NEFSC website). The introduc on of factory trawlers in the 1960s from overseas (including the USSR, Poland, Spain, and Japan) led to the virtual collapse of stocks of groundfish, some of which have yet to recover a er con nued fishing pressure through the 1980s and 1990s. In recent years, fishers have been using more selec ve fishing gears, par cularly in the trawl fishery, where separator trawls and Ruhle trawls have been developed and adopted to reduce bycatch and discarding of nontarget and/or low abundance species. Because of quota restric ons on low abundance species, fishers have also started to target more abundant species and stocks, such as haddock and redfish.
The U.S. fisheries that target the above species are managed by the New England Fisheries Management Council (NEFMC) under the Northeast Mul species Fishery Management Plan (NE Mul species FMP; "the plan"), which was enacted in 1986. Since its incep on, it has been amended several mes to account for changes in fishing ac vity and abundance of the 20 stocks (13 different species) managed under the plan (NEFSC 2012a).
9 Produc on Sta s cs Cod, haddock, and pollock are all globally important commercial species. In 2010, cod was the 10th-most landed species by volume, with a total of 950,950 MT. Global landings of pollock (ranked 26th) and haddock (27th) were 400,920 MT and 396,389 MT, respec vely (FAO 2012).
Landings of all three species from U.S. waters are currently below the 50-year average, although pollock landings are approaching this value. Figure 1 shows the trends in landings for the four species from U.S. vessels from 1950 to 2011. Landings for cod, haddock, and pollock have been fluctua ng between 3,000 MT and 10,000 MT since 2003. For cod, this represents the historical low, whereas pollock and haddock landings have increased from historical lows in the mid-1990s.
For the New England fisheries discussed in this report, the breakdown of which gears are used to catch each of the species is summarized in Table 1 (recommenda ons are provided for the species-gear combina ons that are shown in bold).

Importance to the US/North American market. All three species of groundfish considered in this report are imported into the U.S. In 2010, 17,570 MT of Atlan c cod (with a value of $97.2 million), 34,636 MT of haddock ($151.1 million), and 5,432 MT of pollock ($1.3 million) were imported into the U.S. Figure 2 shows the sources of the imports, and it is clear that the main countries of importance are Canada, Iceland, and China, with Norway being an important source of haddock. It should be noted that imports from China are likely caught in other countries (including the U.S.) and sent to China for processing before being imported to the U.S. markets. There is confusion over the original source of cod from China, and there are concerns over the volume of Illegal, Unregulated, and Unreported landings (IUU) fish entering Chinese (and other Asian) processors (Album 2010).
10 Export data are harder to analyze because they are generally grouped into similar species; e.g., both Atlan c and Pacific cod are grouped together. Data from the NOAA Office of Science and Technology (website) show that, in 2010, a total of 692 MT of haddock and 726 MT of pollock were exported from the U.S., with values of $3 million and $1.3 million, respec vely. It is interes ng to no ce that the value of pollock imports is equal to the value of exports, whereas imports of cod and haddock are much higher than exports—illustra ng the importance of these la er species to U.S. consumers.

Common and market names. Atlan c cod is generally labeled simply as cod, but is also known as true-cod, and smaller cod is referred to as scrod.
Haddock is marketed as haddock, and smaller haddock is also known as scrod.
Pollock is the only known common name in use in the United States; however, this species is referred to as saithe or coley in Europe, where a closely related species, Pollachius pollachius, is given the name pollack. This species should not be confused with walleye (Alaskan) pollock, which is caught in the Pacific.
All the species considered in this report can be found under the name whitefish, a generic term used for firm, white-fleshed fish.
Primary product forms Cod, haddock, and pollock from the New England region are primarily available fresh in the form of whole fish and fillets.
Other forms of cod, haddock, and pollock that may be available on the market include frozen fillets, breaded/ba ered, smoked, salted, or block (typically used for fish s cks, etc.).
13 Assessment This sec on assesses the sustainability of the fishery(s) rela ve to the Seafood Watch Criteria for Fisheries, available at h p://www.seafoodwatch.org.
Criterion 1: Impacts on the species under assessment This criterion evaluates the impact of fishing mortality on the species, given its current abundance. The inherent vulnerability to fishing ra ng influences how abundance is scored, when abundance is unknown. The final Criterion 1 score is determined by taking the geometric mean of the abundance and fishing mortality scores. The Criterion 1 ra ng is determined as follows: Score >3.2=Green or Low Concern Score >2.2 and ≤3.2=Yellow or Moderate Concern Score ≤2.2=Red or High Concern
Ra ng is Cri cal if Factor 1.3 (Fishing Mortality) is Cri cal

Criterion 1 Assessment SCORING GUIDELINES
Factor 1.1 - Inherent Vulnerability Low—The FishBase vulnerability score for species is 0-35, OR species exhibits life history characteris cs that make it resilient to fishing, (e.g., early maturing). Medium—The FishBase vulnerability score for species is 36-55, OR species exhibits life history characteris cs that make it neither par cularly vulnerable nor resilient to fishing, (e.g., moderate age at sexual maturity (5-15 years), moderate maximum age (10-25 years), moderate maximum size, and middle of food chain). High—The FishBase vulnerability score for species is 56-100, OR species exhibits life history characteris cs that make is par cularly vulnerable to fishing, (e.g., long-lived (>25 years), late maturing (>15 years), low reproduc on rate, large body size, and top-predator). Note: The FishBase vulnerability scores is an index of the inherent vulnerability of marine fishes to fishing based on life history parameters: maximum length, age at first maturity, longevity, growth rate, natural mortality rate, fecundity, spa al behaviors (e.g., schooling, aggrega ng for breeding, or consistently returning to the same sites for feeding or reproduc on) and
15 geographic range.
Factor 1.2 - Abundance 5 (Very Low Concern)—Strong evidence exists that the popula on is above target abundance level (e.g., biomass at maximum sustainable yield, BMSY) or near virgin biomass. 4 (Low Concern)—Popula on may be below target abundance level, but it is considered not overfished 3 (Moderate Concern) —Abundance level is unknown and the species has a low or medium inherent vulnerability to fishing. 2 (High Concern)—Popula on is overfished, depleted, or a species of concern, OR abundance is unknown and the species has a high inherent vulnerability to fishing. 1 (Very High Concern)—Popula on is listed as threatened or endangered.
Factor 1.3 - Fishing Mortality 5 (Very Low Concern)—Highly likely that fishing mortality is below a sustainable level (e.g., below fishing mortality at maximum sustainable yield, FMSY), OR fishery does not target species and its contribu on to the mortality of species is negligible (≤ 5% of a sustainable level of fishing mortality). 3.67 (Low Concern)—Probable (>50%) chance that fishing mortality is at or below a sustainable level, but some uncertainty exists, OR fishery does not target species and does not adversely affect species, but its contribu on to mortality is not negligible, OR fishing mortality is unknown, but the popula on is healthy and the species has a low suscep bility to the fishery (low chance of being caught). 2.33 (Moderate Concern)—Fishing mortality is fluctua ng around sustainable levels, OR fishing mortality is unknown and species has a moderate-high suscep bility to the fishery and, if species is depleted, reasonable management is in place. 1 (High Concern)—Overfishing is occurring, but management is in place to curtail overfishing, OR fishing mortality is unknown, species is depleted, and no management is in place. 0 (Cri cal)—Overfishing is known to be occurring and no reasonable management is in place to curtail overfishing.

This results in a score of "high" concern. Ra onale: Biomass declined from 96,864 MT in 1980 to 19,220 MT in 1995 (Figure 5). A er a brief increase in the late 1990s that peaked at 25,624 MT in 2001, biomass declined to a historic low of 10,121 MT in 2010. The biomass has since increased; however, it is s ll well below threshold values, and rebuilding is minimal (NEFSC 2013a). Recruitment (age 1 fish) has been below the series average (13.6 million fish) for the last two decades and has not exceeded the long-term mean since 1991 (NEFSC 2013a). Considering the current trend in low recruitment, it is unlikely that rebuilding of this stock will occur in the short to medium term.

The M0.2 model es mated a SSB2011 of 9,903 MT, compared to a SSBTHRESHOLD of 27,372 MT; the MRAMP model es mated a SSB2011 of 10,221 MT, compared to a SSBTHRESHOLD of 40,100 MT (NEFSC 2013a). Both models show that the biomass is well below threshold targets (Figure 6) and remains in an overfished state. Recruitment has declined in recent years and in both models is at a historical low (NEFSC 2013a).

Factor 1.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GEORGES BANK, HANDLINE UNITED STATES/GEORGES BANK, BOTTOM LONGLINES High Concern Overfishing is occurring in the Georges Bank cod fisheries: total fishing mortality in 2011 was 0.43, compared to an FMSY of 0.18 (NEFSC 2013a). This results in a score of "high" concern. Ra onale:
18 The Georges Bank cod fisheries have failed to meet the FREBUILD target set at 0.18 in Amendment 13 of the New England Mul species Fishery Management Plan (NE Mul FMP) (NEFMC 2004). Management has failed to effec vely reduce fishing mortality to allow rebuilding of the Georges Bank cod stock. A new management system based on hard TACs and quotas (rather than the previous days at sea effort control) was introduced in 2010; however, FMSY PROXY was exceeded in 2010 and 2011, sugges ng that quotas are too high. Cod is caught using large mesh o er trawls, large mesh gillnets, longline, and rod and reel, with each method contribu ng 55%, 36%, 3%, and 2% to landing volumes, respec vely. Because cod is a target species in each of these fisheries, all methods are considered to be contribu ng toward the overfishing.

There is overfishing occurring on the Gulf of Maine stock of Atlan c cod, because F2011 was above FMSY PROXY (NEFSC 2013a). This results in a score of "high" concern. Ra onale:
Fishing mortality was es mated to be 0.86 or 0.90 by the M0.2 and MRAMP models, respec vely. Although this represents a decline from historical highs in the mid-1990s, it is s ll 4.7 or 5.0 mes higher than the FMSY PROXY predicted by each model (NEFSC 2013a). The Gulf of Maine cod fisheries have failed to meet the target of F = 0.21 as set in Amendment 13 of the New England Mul species Fishery Management Plan (NE Mul FMP) (NEFMC 2004). Management has failed to effec vely reduce fishing mortality to allow rebuilding of the Gulf of Maine cod stock. A new management system based on hard TACs and quotas (rather than the previous days at sea effort control) was introduced in 2010; however, FMSY PROXY was exceeded in 2010 and 2011, which suggests that quotas are too high.

That year's spawning stock biomass (SSB2009 ) was es mated to be 196,000 MT, which is above that maximum sustainable yield (SSBMSY ) of 91,000 MT (NEFSC 2010). We have awarded a score of "very low" concern.
Factor 1.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern
The most recent es mate of fishing mortality on the pollock stock was F2009 = 0.07, which is 28% of the FMSY of 0.25 (NEFSC 2012b). There may be some uncertainty in this es mate: without further understanding of the size-based selec vity of fishing gears, the current stock model implies the existence of a large biomass of pollock, accoun ng for 35%–70% of the total, which neither current surveys nor the fishery has been able to confirm (NEFSC 2010). This results in a score of "low" concern. Ra onale: Pollock is caught using large mesh o er trawls and large mesh gillnets, with each gear contribu ng 56% and 39%, respec vely, to landing volumes.
HADDOCK

20 Factor 1.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, HANDLINE UNITED STATES/GEORGES BANK, BOTTOM LONGLINES Very Low Concern
The 2010 spawning stock biomass, SSB2010 , for Georges Bank haddock was es mated to be 167,278 MT, which is above that maximum sustainable yield, SSBMSY , of 124,900 MT (NEFSC 2012a). We have awarded a score of "very low" concern.
Ra onale: Spawning stock biomass peaked in 2007 at over 250,000 MT and has since decreased (Figure 7), although it is s ll above biological reference points and is considered rebuilt. Short-term projec ons predict a further increase in biomass between 2011 and 2015, ranging from 147,700 MT to 240,200 MT (NEFSC 2012a). One of the major factors in this projected increase is the strong 2010 year-class recrui ng to the fishery, which was es mated to be 750 million age-1 fish (compared to an average of 19 million between 2000 and 2009). There is s ll uncertainty over the size of this cohort; however, the projec ons described have taken this uncertainty into account.

The spawning stock biomass of haddock in the Gulf of Maine in 2013, SSB2013, was 4,153 MT, which is 101% of the SSBMSY proxy of 4,108 MT (NEFSC 2014). This results in a score of "low" concern.
Factor 1.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, HANDLINE UNITED STATES/GEORGES BANK, BOTTOM LONGLINES Very Low Concern
The Georges Bank haddock popula on is considered to be rebuilt and is being fished below the FMSY proxy of 0.39, at a level of 0.24 (NEFSC 2012a). We have awarded a score of "very low" concern. Ra onale: Haddock is caught using rod and reel, large mesh o er trawls, and bo om longlines, which contribute 1%, 89%, and 8%, respec vely, to landing volumes.
UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, HANDLINE UNITED STATES/GULF OF MAINE, BOTTOM LONGLINES Low Concern
The Gulf of Maine haddock stock is not experiencing overfishing because F2013 was 0.39, compared to an FMSY proxy of 0.46 (NEFSC 2014). Fishing mortality is rated as a "low" concern because fishing mortality is below FMSY.
22 Criterion 2: Impacts on other species All main retained and bycatch species in the fishery are evaluated in the same way as the species under assessment were evaluated in Criterion 1. Seafood Watch® defines bycatch as all fisheries-related mortality or injury to species other than the retained catch. Examples include discards, endangered or threatened species catch, and ghost fishing. To determine the final Criterion 2 score, the score for the lowest scoring retained/bycatch species is mul plied by the discard rate score (ranges from 0-1), which evaluates the amount of non-retained catch (discards) and bait use rela ve to the retained catch. The Criterion 2 ra ng is determined as follows: Score >3.2=Green or Low Concern Score >2.2 and ≤3.2=Yellow or Moderate Concern Score ≤2.2=Red or High Concern
Ra ng is Cri cal if Factor 2.3 (Fishing Mortality) is Cr cal

Discards and landings of skates for the large mesh gillnet fishery are much lower than for the large mesh o er trawl and extra-large mesh gillnet fisheries (not considered in this report) {NMFS 2011b}. But skate landings and discards are not separated by species, so the impact of the large mesh gillnet fishery cannot be determined precisely. Therefore, it has been scored alongside the large mesh o er trawl fishery for the purposes of this report. Skate species are not separated in the na onal bycatch report, so the discard rate must be considered collec vely. Discards of the skate complex are equivalent to 27.5% of trawl landings and 6.5% of longline landings by weight {NMFS 2011b}.

UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL High Concern
The most recent assessment of Cape Cod/Gulf of Maine yellowtail flounder indicated that F2010 = 0.36 and FMSY = 0.26, so F2007 /F MSY = 1.38 and overfishing was occurring (NEFSC 2012a). But fishing mortality had been declining since 2004 and was at its lowest point in the me series (NEFSC 2008) (NEFSC 2012a). The stock is currently in year 8 of its 19-year rebuilding plan (NMFS 2012c). Between 1994 and 2010, discards (across all gear types) averaged 17% of total landings (NEFSC 2012a). We have scored this as "high" concern. Ra onale:
43 Amendment 16 to the NE Mul species FMP adopted a broad suite of management measures to achieve fishing mortality targets. To accomplish the reduc on in fishing mortality, the amendment will expand the use of sectors that have their catch limited by a quota and implemented Accountability Measures (AMs) to prevent overfishing. In par cular, these AMs include differen al Days-At-Sea (DAS) coun ng to correct for over- or under-harves ng, and a transi on in 2012 from an effort control fishery to one managed through hard TACs (total allowable catch). In addi on, this amendment will implement new requirements for establishing allowable biological catch (ABC), annual catch limits (ACLs), and AMs for the stocks managed under the FMP (Federal Register 2010).
Factor 2.4 - Discard Rate
UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL 40-60% Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b). Skate species are believed to have a higher post-release survival rate than other fish species. A recent study revealed that the post-release mortality of the skate complex (species combined) was 19%, with the highest post-release mortality exhibited by smooth skate at 60% (Mandelman et al. 2013). Because of the uncertainty about which skate species are discarded during the groundfish fishery, a precau onary assump on is made that they are all smooth skate; this results in an overall discard rate of 43%. Ra onale: It is worth no ng that, in recent years, fishers have been adop ng more selec ve gears in an a empt to reduce bycatch of non-target, low abundance species. Separator trawls and Ruhle trawls are designed to take advantage of the different behaviors of different species: catching species such as haddock that tend to swim upward and allowing the release of species that tend to swim down during capture, such as cod and fla ish.

Very High Concern
B/BMSY = 0.03 (NMFS 2016); current abundance es mates are below the limit reference point and at historical lows. NMFS classifies the thorny skate stock as overfished (NMFS 2016). Thorny skate is considered “Cri cally Endangered” in U.S. waters by the IUCN Red List (globally, the species is listed as “Vulnerable”). Seafood Watch considers abundance of thorny skate to be a “very high” conserva on concern. Ra onale: For thorny skate, the 3-year (2012–2014) average survey biomass of 0.13 kg/tow shows an increase on the previous 3-year average, but is only 3.1% of the BMSY target of 4.13 kg/tow. This stock is 12 years into the rebuilding period (end date of 2028), yet it con nues to decline without any signs of rebuilding. To ensure that an overfished species will achieve target levels, skate regula ons require the Council to take management ac on (e.g., priori zing research into thorny skate popula on dynamics, among the ac ons to halt the decline of thorny skate biomass) (Sosebee 2015). Thorny skate is currently a Species of Concern, but a new pe on has been submi ed to the Endangered Species Act in May 2015 to have the species listed; it is currently being evaluated by NOAA (Sosebee 2015). Biomass reference points are based en rely on NEFSC survey data because reliable landings and discard informa on are not available by species. For all skate species but barndoor, the BMSY proxy is defined as the 75th percen le of the appropriate survey biomass index me series for that species (Brown et al. 2013).

The use of a biomass index to determine fishing mortality results in a high level of uncertainty, and fishing mortality rela ve to maximum sustainable yield (MSY) is considered unknown. Annual catch limits are designed to prevent impacts of fishing from increasing to unsustainable levels, and all landings of thorny skate are prohibited (NEFMC 2011a). Nevertheless, together with the other skate species, thorny skate is frequently taken as bycatch and discarded by vessels targe ng groundfish. As a result, o er trawling is the principal source of fishing mortality for all skates discussed in this report (Sosebee 2015). Seafood Watch considers fishing mortality to be a “moderate” conserva on concern. Ra onale: The fishing mortality reference points for skates are based on changes in survey biomass indices. If the 3-year moving average of the survey biomass index for a skate species declines by more than the average coefficient of varia on (CV) of the survey me series, then fishing mortality is assumed to be greater than FMSY and overfishing is occurring for that skate species (Sosebee 2015).

Spiny dogfish has been shown to have a 55% overall mortality rate in gillnet fisheries (Rulifson 2007). Therefore, the overall discard rate was adjusted to account for the survival rate of spiny dogfish, resul ng in an overall discard rate of 28%.

Factor 2.2 - Abundance
UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL High Concern The observed es mated spawning stock biomass (SSB) in 2014 was 5,275 MT, which is 79% of the biomass target for an overfished stock (SSBMSY = 6,700, with a threshold of 50% of SSBMSY ) (NEFSC 2015d). But when the observed abundance is corrected for retrospec ve error, an abundance es mate of 2,883 MT is found. This is 43% of SSBMSY , therefore the stock is in an overfished condi on (NEFSC 2015d). Seafood Watch considers stock abundance to be a "high" conserva on concern for Georges Bank blackback. Ra onale: The latest assessment of the Georges Bank blackback stock found that the 2014 SSB es mate, when adjusted for retrospec ve error (83% for SSB), is outside the 90% confidence interval of the unadjusted 2014 point es mate (NEFSC 2015d). Therefore, the 2014 SSB value used in the stock status determina on was the retrospec ve-adjusted value of 2,883 MT (NEFSC 2015d), which is 43% of the biomass target (SSBMSY = 6,700) for an overfished stock. Therefore, the stock is considered to be overfished. As of December 31, 2015, NMFS listed Georges Bank blackback as “overfished” and rebuilding, in year 6 of a 7-year plan (NMFS 2015c). "Short-term projec ons of biomass were derived by sampling from a cumula ve distribu on func on of recruitment es mates (1982--2013 YC) from the final run of the ADAPT VPA model. The annual fishery selec vity, maturity ogive, and mean weights-at-age used in the projec on are the most recent 5-year averages (2010--2014).

Thus, the value used in the stock status determina on was the adjusted value of F = 0.778, which is 145% of the overfishing threshold (FMSY = 0.536), and suggests that the stock is currently undergoing overfishing. Fishing mortality is scored as "high" concern (NEFSC 2015d). Ra onale: The observed 2014 fully selected fishing mortality (F; fully selected ages [ages 4–6]) was es mated to be 0.379, which is 71% of the overfishing threshold (FMSY = 0.536) (NEFSC 2015d).

Very High Concern The humpback whale is listed as endangered under the United States Endangered Species Act. This is scored as "very high" concern. Ra onale: The best abundance es mate for humpback whale in the Gulf of Maine is 847 individuals, with a minimum popula on of 823 individuals (Waring et al. 2013a). The popula on in the Gulf of Maine is steadily increasing, which is consistent with an average increase in the wider North Atlan c popula on as a whole; however, the popula on may be below the op mum sustainable popula on (OSP) within the U.S. exclusive economic zone (EEZ) (Waring et al 2013a).

Entanglements were not specific to a par cular fishery; however, 1.85 average annual mortali es or serious injuries occurred in the same region as the Northeast Sink Gillnet fishery. This rate of interac on is greater than the PBR of 1 whale per year. Between 2001 and 2006, there was one reported mortality associated with a gillnet, but it was not possible to determine which gillnet fishery was responsible.

The latest stock assessment shows that current fishing mortality (F2010 = 0.47) is higher than the target fishing mortality (FMSY proxy = 0.27) (NEFSC 2012a). Although fishing mortality has declined since 1996, it is s ll about twice as high as the es mated fishing mortality in the early 1990s. Discards from the large mesh o er trawl make up the majority of discards; however, total discards are considered to be a minor part of the overall catch of witch flounder (NEFSC 2012a). Ra onale:
58 Amendment 16 to the NE Mul species FMP adopted a broad suite of management measures to achieve fishing mortality targets. Specific to witch flounder, a rebuilding plan has been proposed that would have a 75% likelihood of rebuilding the stock by 2017. To accomplish the reduc on in fishing mortality, the amendment expanded the use of sectors that have their catch limited by a quota and implemented Accountability Measures (AMs) to prevent overfishing. In 2010, there was a transi on from an effort control fishery to one managed through hard TACs (total allowable catch). In addi on, this amendment implemented new requirements for establishing allowable biological catch (ABC), annual catch limits (ACLs), and AMs for the stocks managed under the FMP (Federal Register 2010).
Factor 2.4 - Discard Rate UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL 40-60% Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b). Skate species are believed to have a higher post-release survival rate than other fish species. A recent study revealed that the post-release mortality of the skate complex (species combined) was 19%, with the highest post-release mortality exhibited by smooth skate at 60% (Mandelman et al. 2013). Because of the uncertainty about which skate species are discarded during the groundfish fishery, a precau onary assump on is made that they are all smooth skate; this results in an overall discard rate of 43%. Ra onale: It is worth no ng that, in recent years, fishers have been adop ng more selec ve gears in an a empt to reduce bycatch of non-target, low abundance species. Separator trawls and Ruhle trawls are designed to take advantage of the different behaviors of different species: catching species such as haddock that tend to swim upward and allowing the release of species that tend to swim down during capture, such as cod and fla ish.
59 Criterion 3: Management Effec veness Management is separated into management of retained species (harvest strategy) and management of non- retained species (bycatch strategy). The final score for this criterion is the geometric mean of the two scores. The Criterion 3 ra ng is determined as follows: Score >3.2=Green or Low Concern Score >2.2 and ≤3.2=Yellow or Moderate Concern Score ≤2.2 or either the Harvest Strategy (Factor 3.1) or Bycatch Management Strategy (Factor 3.2) is Very High Concern = Red or High Concern
Ra ng is Cri cal if either or both of Harvest Strategy (Factor 3.1) and Bycatch Management Strategy (Factor 3.2) ra ngs are Cri cal.

The NEFMC manages the groundfish fishery through a collec ve FMP that covers 20 stocks from 13 species. Grouping species together allows the NEFMC to manage these mixed fisheries more effec vely than if individual species FMPs were used. Because of the historical exploita on that stocks have been exposed to, a number of stocks are depleted or in a state of rebuilding. The NEFMC has recently introduced a new management system that should improve the rate of recovery of stocks. There is a considerable effort to collect data in these fisheries through logbooks and observer coverage; these data (along with fishery- independent data) guide stock assessments. On the majority of occasions, the NEFMC takes into account the scien fic informa on provided by stock assessments; but in some instances, TACs have been set too high in response to social and economic need.
61 Subfactor 3.1.1 – Management Strategy and Implementa on Considera ons: What type of management measures are in place? Are there appropriate management goals, and is there evidence that management goals are being met? To achieve a highly effec ve ra ng, there must be appropriate management goals, and evidence that the measures in place have been successful at maintaining/rebuilding species.

62 The New England fisheries for cod, haddock, and pollock are managed by the New England Fisheries Management Council (NEFMC) through the Northeast Mul species Fishery Management Plan (NE Mul species FMP), alongside nine other species of fla ish and groundfish. Originally enacted in 1985, the NE Mul species FMP has been amended a number of mes to improve the management of the relevant fisheries, including the introduc on of gear restric ons (e.g., mesh size, number of nets/hooks), seasonal closures, spa al closures, minimum landing sizes, trip limits on pounds of fish landed, limited access (a restric on on the number of vessels able to work within the fishery), effort limits based on a days-at-sea (DAS) system, and most recently a system based on transferable quotas set against a hard annual catch limit (ACL) (this replaced the previous effort-based limita on of the DAS system in 2010). In 2010, Amendment 16 to the NE Mul species FMP greatly expanded catch share, or sector-based, management. The sectors func on essen ally as coopera ves because they are self-selec ng and largely self- regula ng (albeit within a framework designated and closely monitored by federal agencies). The sectors are exempt from many of the effort controls previously used to manage the fishery; instead, they adhere to an overall hard quota known as an annual catch limit (ACL), which is subdivided into annual catch en tlements (ACE) allocated to each sector. The shi to output management instead of effort management enables efficiency gains by allowing increased opera onal efficiency. Although it is op onal to join the sectors, the majority of fishers have chosen to par cipate: sector vessels made 65% of all NE Mul species landings in 2010, including 98% of groundfish and 54% of non-groundfish (Ki s et al. 2011) (Labaree 2012) (Federal Register 2012). Under the Magnuson-Stevens Act, the ACL must be set less than or equal to the acceptable biological catch (ABC) (to account for management uncertainty), which must be set less than or equal to the overfishing level (OFL) (to account for any scien fic uncertainty in the stock assessment) (Figure 16) (Federal Register 2009a). Fishing mortality targets are set for each stock independently, based on achieving MSY in the long term. Therefore, for stocks that are overfished (and may also be subject to overfishing), the target fishing mortality is set at a level that will have a reasonable probability (>50%) of ensuring rebuilding of the stock within the meline set within the relevant rebuilding program (see “Recovery of Stocks of Concern”, factor 3.1.2). But if a sector were to approach the ACE for one of the target stocks, then the area inhabited by that stock is closed to all gears capable of catching that stock, resul ng in a poten al "under-harvest" of more abundant stocks. The sector system allows fishers to share, trade, or lease quota within a fishery, thus reducing the chance of overfishing depleted stocks while targe ng more abundant stocks; and if a sector is nearing its quota for a par cular species, it may be possible to lease it from another sector. There have been some concerns with the management strategy in the past, par cularly with respect to depleted stocks (see “Recovery of Stocks of Concern,” factor 3.1.2). In addi on, target total allowable catches (TACs) have been set too high because of errors in stock assessments, and there has been a need for increased precau on (see “Scien fic Advice,” factor 3.1.4). But the management system has substan ally changed under Amendment 16, which is expected to reduce the race to fish and to improve conserva on outcomes. For example, discarding appears to have been reduced, and the fishery now relies on hard ACLs (which include discards) rather than target TACs—all of which helps reduce the likelihood of exceeding sustainable fishing mortality rates for targeted stocks. In addi on, sectors have not exceeded their ACEs, whereas in the past it was possible for target TACs to be exceeded because the regula ons were based on effort control (DAS) rather than output control (Ki s et al 2011). The new management regime has not been in place long enough to fully assess its impact. This results in a score of "moderately effec ve."

Subfactor 3.1.2 – Recovery of Species of Concern Considera ons: When needed, are recovery strategies/management measures in place to rebuild overfished/threatened/ endangered species or to limit fishery’s impact on these species and what is their likelihood of success? To achieve a ra ng of Highly Effec ve, rebuilding strategies that have a high likelihood of success in an appropriate meframe must be in place when needed, as well as measures to minimize mortality for any overfished/threatened/endangered species.

64 There are a number of stocks of concern affected by the fisheries managed under the NE Mul species FMP, and the management plan has had varying degrees of success in recovering these stocks. Under the NE Mul species FMP, and in accordance with the Magnuson-Stevens Act, overfished stocks are subject to rebuilding programs that aim to rebuild the stock within a given meframe (usually 10 years). But for some stocks, in which decreasing the fishing mortality to a level that would allow rebuilding is likely to have nega ve social and/or economic effects, the melines are extended; for example, Georges Bank cod has a rebuilding target of 2026 (Federal Register 2004). The rebuilding programs are based on mee ng fishing mortali es that are likely to allow rebuilding of the stock within the given me period (FREBUILD); these are typically a reduc on from the fishing mortali es that the stocks were subjected to when the programs were established in 2003 (implemented in 2004 fishing year). Any reduc on in fishing mortality was conducted in one of two ways: through phased reduc on strategy, in which the fishing mortality was gradually reduced over the rebuilding period to reach the target biomass with median probability; or through an adap ve rebuilding strategy, in which fishing mortality was held at or below FMSY from 2004 to 2009, at which point adjustments would be made in order to achieve the target biomass by the end of the rebuilding period. The most recent stock assessments have shown that a number of stocks of concern have not yet been rebuilt and that the targets set within the rebuilding programs have not been met (e.g., Georges Bank cod, Gulf of Maine cod, and Cape Cod yellowtail flounder) (NMFS 2011a) (NEFSC 2012a). With the recent adop on of a new management system, it is too early to determine whether the rebuilding targets will be met by the end of the rebuilding period. But there are a number of stocks that have rebuilt prior to the end of the rebuilding period (typically due to strong recruitment and good survival of abundant year-classes during periods of reduced exploita on). These stocks include Georges Bank haddock, Gulf of Maine haddock, Acadian redfish, and pollock (NMFS 2011a) (NEFSC 2012a). Although there is concern that some of the stocks have yet to meet their rebuilding targets, other stocks have rebuilt within the specified melines, and the new management system is likely to improve rebuilding of stocks due to reduced levels of discarding. This is rated as "moderately effec ve."
Subfactor 3.1.3 – Scien fic Research and Monitoring Considera ons: How much and what types of data are collected to evaluate the health of the popula on and the fishery’s impact on the species? To achieve a Highly Effec ve ra ng, popula on assessments must be conducted regularly and they must be robust enough to reliably determine the popula on status.
65 UNITED STATES / GEORGES BANK, BOTTOM LONGLINES UNITED STATES / GEORGES BANK, HANDLINE UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES / GULF OF MAINE, BOTTOM LONGLINES UNITED STATES / GULF OF MAINE, HANDLINE UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM TRAWL Moderately Effec ve There is a high level of scien fic research and monitoring associated with the Northeast U.S. fisheries, including regular stock assessments and gear modifica on trials (NMFS 2011b). Much of the scien fic research and monitoring is carried out by the Northeast Fisheries Science Center (NEFSC), which provides the NEFMC with scien fic advice, including stock assessments, to guide the management of the fishery. A number of independent and academic ins tu ons also conduct research in the region, including tes ng gear modifica ons and conduc ng tagging experiments to monitor fish popula ons. Stock assessments account for all sources of fishing mortality, including commercial and recrea onal landings and discards (NEFSC 2008) (NEFSC 2012a), as well as environmental factors. Thus there is a wealth of both fishery-dependent and fishery-independent data available to NEFMC and NMFS to ensure that the fishery is managed effec vely. There are concerns about a con nued retrospec ve pa ern that overes mates biomass and underes mates fishing mortality in some stocks (for example, Georges Bank cod), and stock assessments are taking account of this pa ern, which is thought to be caused partly by increased natural mortality rates (NEFSC 2013a). Observer coverage in the fishery comprises two forms: the Northeast Fisheries Observer Program (NEFOP) and the At-Sea Monitoring (ASM) program. The level of observer coverage aims to ensure precision in the catch levels of each managed stock, based on a methodology set out in the Standard Bycatch Repor ng Methodolgy (SBRM). The SBRM was vacated by the courts because it contained discre ons to be made that allowed observer coverage to be below the amount required to meet an acceptable level of precision (CV < 30), for budget reasons. The ques ons surrounding the observer program and the appropriate level of coverage prevent the management system from achieving the highest possible score for scien fic research and monitoring. Thus, it is scored as "moderately effec ve." Ra onale: Standard bycatch repor ng methodology (SBRM) indicates that a simple percentage of observer coverage is not appropriate; instead, SBRM indicates that the appropriate metric of coverage is the coefficient of varia on (CV), or the ra o of the square root of the variance of the bycatch es mate (i.e., standard error) to the es mate itself. SBRM establishes a standard level of precision of CV = 0.3 (Federal Register 2008).
Subfactor 3.1.4 – Management Record of Following Scien fic Advice Considera ons: How o en (always, some mes, rarely) do managers of the fishery follow scien fic recommenda ons/advice (e.g. do they set catch limits at recommended levels)? A Highly Effec ve ra ng is given if managers nearly always follow scien fic advice.

Under the Magnuson-Stevens Act, the NEFMC has a duty to consider the social and economic consequences of the quotas that it sets, and for some stocks, par cularly cod, there are concerns among environmental groups that the council will follow a less precau onary scien fic op on in order to meet social and economic goals. Although NEFMC is implemen ng scien fic advice on a regular basis, there is poten al room for improvement by implemen ng a more precau onary approach, par cularly when considering the poten al retrospec ve pa ern (as previously discussed). This factor is scored as "moderately effec ve."
Subfactor 3.1.5 – Enforcement of Management Regula ons Considera ons: Do fishermen comply with regula ons, and how is this monitored?

67 A variety of enforcement measures are in place in the New England groundfish fishery. All vessels fishing in the mul species fishery are required to be fi ed with a vessel monitoring system (VMS) (Federal Register 2006), which allows fishery officers to remotely monitor the loca on of each vessel. VMS systems enable fishery managers not only to monitor where catches are being taken, but also to enforce spa al closures, of which there are a number in the Northwest Atlan c. Enforcement of fishery legisla on at sea is a coopera ve opera on between coastal states, the NOAA Office of Law Enforcement (OLE), and the United States Coast Guard. OLE officers conduct dockside inspec ons and inspect fish processing plants (OLE webpage), and the Coast Guard inspect vessels at sea (Nies 2013). OLE enforces fisheries legisla on, including minimum landing sizes, reten on of prohibited species, and gear restric ons. Viola on of such management measures can result in criminal or civil ac ons as well as fines, loss of quota, or imprisonment for more serious cases. Under Amendment 16 of the Mul species Fishery Management Plan, accountability measures (AMs) were established (Federal Register 2010). AMs are required to ensure accountability within the fishery and to prevent overfishing. Proac ve AMs are designed to prevent allowable catch limits (ACLs) from being exceeded, whereas reac ve AMs are designed to correct any overages if they occur (Federal Register 2012). AMs can result in a reduc on or complete loss of quota for a sector that regularly or greatly exceeds its quota (Federal Register 2010). It is thought that loss of a community pool will encourage a greater level of self- management, thus improving compliance throughout the fishery. This factor is scored as "highly effec ve."
Subfactor 3.1.6 – Management Track Record Considera ons: Does management have a history of successfully maintaining popula ons at sustainable levels or a history of failing to maintain popula ons at sustainable levels?

68 The fish stocks in the Northwest Atlan c have been subject to fishing pressure for centuries; as a result, many stocks have become overfished or depleted. Management of the fisheries through the NEFMC began in 1977, when the fishery management councils were formed through the Magnuson-Stevens Fishery Conserva on and Management Act (MS Act) (then called the Magnuson Fishery Conserva on and Management Act 1976) (NEFMC website). During the early years of management under the NEFMC, many stocks underwent declines in biomass under increasing fishing mortali es, such as the Acadian redfish, Georges Bank cod, and Gulf of Maine cod (NEFSC 2008). But in more recent years, a er revision of the MS Act and the requirement for fisheries management councils to implement rebuilding programs, there have been increasing biomasses in a number of stocks (NEFSC 2008), and more recent changes in management suggest that these improvements will con nue. It is too early to determine whether the sector-based management system will enable stocks to rebuild and stabilize at a sustainable level. This factor is rated as "moderately effec ve."
Subfactor 3.1.7 – Stakeholder Inclusion Considera ons: Are stakeholders involved/included in the decision-making process? Stakeholders are individuals/groups/organiza ons that have an interest in the fishery or that may be affected by the management of the fishery (e.g., fishermen, conserva on groups, etc.). A Highly Effec ve ra ng is given if the management process is transparent and includes stakeholder input.

A number of regula ons are in place that require fisheries managers to reduce the impacts of fishing ac vi es on non-target popula ons. Repor ng of bycatch encourages reduc on efforts while providing data for scien fic research and stock assessments. The observer program provides considerable data to aid in stock assessments of target and bycatch species. Enforcement is generally good, although there are concerns over the effec veness of the regula ons with respect to the use of pingers on gillnets to reduce the bycatch of cetaceans (e.g., harbor porpoise).
Subfactor 3.2.2 – Management Strategy and Implementa on Considera ons: What type of management strategy/measures are in place to reduce the impacts of the fishery on bycatch species and how successful are these management measures? To achieve a Highly Effec ve ra ng, the primary bycatch species must be known and there must be clear goals and measures in place to minimize the impacts on bycatch species (e.g., catch limits, use of proven mi ga on measures, etc.).

Moderately Effec ve The Magnuson-Stevens Act (MSA) requires fisheries management to prevent overfishing from occurring, and for depleted and overfished stocks to be rebuilt. Marine mammals are further protected under the Marine Mammal Protec on Act (MMPA) of 1972, which requires the maintenance of marine mammal popula ons above their op mum sustainable level and the rebuilding of depleted popula ons. The Endangered Species Act of 1973 provides protec on for species that are endangered or threatened with ex nc on, including fish, marine mammals, turtles, and seabirds. These three pieces of legisla on provide a framework directed at ensuring that FMPs are designed and implemented in a way that prevents overfishing and allows recovery of stocks caught within a fishery, whether the stocks are targeted or caught incidentally. The MSA requires that all management measures must minimize bycatch to the extent prac cable, and minimize mortality of bycatch when bycatch is unavoidable (Magnuson-Stevens Fishery Conserva on and Management Act 1976). To comply with the MSA requirement of including a standardized bycatch repor ng methodology (SBRM) in all FMPs, and prompted by successful lawsuits by Oceana, the Conserva on Law Founda on, and the Natural Resources Defense Council, the NEFMC and the Mid-Atlan c Fisheries Management Council jointly developed an omnibus amendment, corresponding to Amendment 15 to the NE mul species FMP. The SBRM amendment is meant to “establish, maintain, and u lize biological sampling programs designed to minimize bias to the extent prac cable, thus promo ng accuracy while maintaining sufficiently high levels of precision” (Federal Register 2008). The original SBRM was considered inadequate and was vacated by the courts in 2011; the NMFS is currently developing a replacement ac on (pers. comm., Brogan 2013). To be approved to operate, sectors must submit an opera ons plan to the regional administrator (NEFMC) that details (among other things) how bycatch of regulated species and ocean pout will be avoided to prevent allowable catch en tlement overages. To date, this has not occurred because NMFS is currently funding both the Northeast Fisheries Observer Program (NEFOP) and the At-Sea Monitoring program (ASM); sector opera on plans will be required when the financial burden for ASM passes from NMFS to the individual sectors (pers. comm., Litsinger 2013). To address harbor porpoise mortality in gillnet fisheries, NMFS updated its Harbor Porpoise Take Reduc on Plan (HPTRP) to reduce mortality below the PBR threshold level. Measures implemented in New England include new areas with acous c deterrent (“pinger”) requirements as well as “consequence” closure areas that would seasonally close certain areas to gillnet fishing if the observed average bycatch rate exceeds the target bycatch rate for two consecu ve management seasons. Acous c deterrents, or “pingers,” are highly effec ve in reducing harbor porpoise bycatch in gillnets when used properly, with a controlled scien fic study showing a 92% reduc on in harbor porpoise bycatch (Kraus et al. 1997). Area closures, if triggered and properly enforced, should be highly effec ve, too. But at this me, levels of bycatch remain above 50% of the PBR level for the species, so management is considered uncertain un l data demonstrate that it has fallen below that threshold, par cularly considering recent concerns with regula ons compliance (see “Enforcement,” factor 3.2.5). This factor is scored as "moderately effec ve."

Observers are trained biologists who collect data on fishing ac vi es onboard commercial vessels, to provide robust data to support science and management programs. Observers in the Northeast Fisheries Observer Program (NEFOP) record weights of kept and discarded fish and crustacean species on observed hauls, as well as biological informa on (length, age, sex, and tags) from all species caught, including marine mammals and seabirds. Currently, observer coverage targets are 25% for sector vessels and 17% for common pool vessels. As of March 2013, the average observer coverage on sector vessels was es mated at 20.5% for the 2012–2013 fishing year, with coverage of 11% for the common pool (NEFOP 2013). Observer coverage has decreased since the 2010–2011 season; however, current levels of observer coverage are higher than in 2006–2008, when the average was below 10% for groundfish trawl and gillnet fisheries in the Northeast (NMFS 2011b). Because of the rarity of some bycatch species, the same level of observer coverage that is sufficient for monitoring retained species may not always be sufficient for monitoring bycatch species; similarly, a given level of coverage may be sufficient for a large fishery but not a small one. The level of observer coverage aims to ensure precision in the catch levels of each managed stock, based on a methodology set out in the Standard Bycatch Repor ng Methodolgy (SBRM). The SBRM was vacated by the courts because it contained discre ons to be made that allowed observer coverage to be below the amount required to meet an acceptable level of precision (CV < 30), for budget reasons. The ques ons surrounding the observer program and the appropriate level of coverage prevent the management system from achieving the highest possible score for scien fic research and monitoring. We have scored this factor as "moderately effec ve." Ra onale: Standard bycatch repor ng methodology (SBRM) indicates that a simple percentage of observer coverage is not appropriate; instead, SRBM indicates that the appropriate metric of coverage is the coefficient of varia on (CV), or the ra o of the square root of the variance of the bycatch es mate (i.e., standard error) to the es mate itself. SBRM establishes a standard level of precision of CV = 0.3 (Federal Register 2008).
Subfactor 3.2.4 – Management Record of Following Scien fic Advice Considera ons: How o en (always, some mes, rarely) do managers of the fishery follow scien fic recommenda ons/advice (e.g., do they set catch limits at recommended levels)? A Highly Effec ve ra ng is given if managers nearly always follow scien fic advice.

Moderately Effec ve See factor 3.1.4 in the Harvest Strategy sec on.
Subfactor 3.2.5 – Enforcement of Management Regula ons Considera ons: Is there a monitoring/enforcement system in place to ensure fishermen follow management regula ons and what is the level of fishermen’s compliance with regula ons? To achieve a Highly Effec ve ra ng, there must be consistent enforcement of regula ons and verifica on of compliance. UNITED STATES / GEORGES BANK, BOTTOM LONGLINES UNITED STATES / GEORGES BANK, HANDLINE UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES / GULF OF MAINE, BOTTOM LONGLINES UNITED STATES / GULF OF MAINE, HANDLINE UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM TRAWL Highly Effec ve See factor 3.1.5 in the Harvest Strategy sec on.
UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM GILLNET Moderately Effec ve Enforcement may be somewhat weaker for bycatch species than for retained species. For instance, when a study demonstrated the effec veness of acous c pingers in reducing harbor porpoise bycatch (Kraus et al. 1997), a take reduc on plan was subsequently implemented in the fishery, and harbor porpoise bycatch decreased from above 1,500 animals per year prior to 1996 to below 500 animals per year during 1999–2001. But within several years of implementa on, compliance decreased and bycatch of harbor porpoises started to increase (Orphanides 2012a) (Orphanides 2012b). Outreach ac vi es increased in 2006–2007 to remind fishers about TRP requirements, so compliance subsequently increased and bycatch started decreasing again (NMFS 2011b), reaching a mean serious injury and annual mortality of 511 animals during 2005–2009 (Waring et al. 2013b). Concerns about compliance remain. Recently published data from 2009–2010 suggest that acous c pinger deployment rates in the Gulf of Maine were just 43%, with full compliance (accoun ng for func onality as well) at only 6.7% (Orphanides 2012a). Although observed deployment rates were higher in 2011–2012 (73% for Southern New England and 80% for the Gulf of Maine), improvement is s ll needed. Target bycatch rates for harbor porpoises con nue to be exceeded; this is believed to be the result of inadequate compliance with deployment regula ons as well as malfunc oning pingers (Orphanides 2012b).
73 Criterion 4: Impacts on the habitat and ecosystem This Criterion assesses the impact of the fishery on seafloor habitats, and increases that base score if there are measures in place to mi gate any impacts. The fishery’s overall impact on the ecosystem and food web and the use of ecosystem-based fisheries management (EBFM) principles is also evaluated. Ecosystem Based Fisheries Management aims to consider the interconnec ons among species and all natural and human stressors on the environment. The final score is the geometric mean of the impact of fishing gear on habitat score (plus the mi ga on of gear impacts score) and the Ecosystem Based Fishery Management score. The Criterion 2 ra ng is determined as follows: Score >3.2=Green or Low Concern Score >2.2 and ≤3.2=Yellow or Moderate Concern Score ≤2.2=Red or High Concern
Ra ng cannot be Cri cal for Criterion 4.

Criterion 4 Assessment SCORING GUIDELINES
Factor 4.1 - Impact of Fishing Gear on the Habitat/Substrate 5 (None) - Fishing gear does not contact the bo om 4 (Very Low) - Ver cal line gear 3 (Low)—Gears that contacts the bo om, but is not dragged along the bo om (e.g. gillnet, bo om
74 longline, trap) and is not fished on sensi ve habitats. Bo om seine on resilient mud/sand habitats. Midwater trawl that is known to contact bo om occasionally 2 (Moderate)—Bo om dragging gears (dredge, trawl) fished on resilient mud/sand habitats. Gillnet, trap, or bo om longline fished on sensi ve boulder or coral reef habitat. Bo om seine except on mud/sand 1 (High)—Hydraulic clam dredge. Dredge or trawl gear fished on moderately sensi ve habitats (e.g., cobble or boulder) 0 (Very High)—Dredge or trawl fished on biogenic habitat, (e.g., deep-sea corals, eelgrass and maerl) Note: When mul ple habitat types are commonly encountered, and/or the habitat classifica on is uncertain, the score will be based on the most sensi ve, plausible habitat type.
Factor 4.2 - Mi ga on of Gear Impacts +1 (Strong Mi ga on)—Examples include large propor on of habitat protected from fishing (>50%) with gear, fishing intensity low/limited, gear specifically modified to reduce damage to seafloor and modifica ons shown to be effec ve at reducing damage, or an effec ve combina on of ‘moderate’ mi ga on measures. +0.5 (Moderate Mi ga on)—20% of habitat protected from fishing with gear or other measures in place to limit fishing effort, fishing intensity, and spa al footprint of damage caused from fishing. +0.25 (Low Mi ga on)—A few measures are in place (e.g., vulnerable habitats protected but other habitats not protected); there are some limits on fishing effort/intensity, but not ac vely being reduced 0 (No Mi ga on)—No effec ve measures are in place to limit gear impacts on habitats
Factor 4.3 - Ecosystem-Based Fisheries Management 5 (Very Low Concern)—Substan al efforts have been made to protect species’ ecological roles and ensure fishing prac ces do not have nega ve ecological effects (e.g., large propor on of fishery area is protected with marine reserves, and abundance is maintained at sufficient levels to provide food to predators) 4 (Low Concern)—Studies are underway to assess the ecological role of species and measures are in place to protect the ecological role of any species that plays an excep onally large role in the ecosystem. Measures are in place to minimize poten ally nega ve ecological effect if hatchery supplementa on or fish aggrega ng devices (FADs) are used. 3 (Moderate Concern)—Fishery does not catch species that play an excep onally large role in the ecosystem, or if it does, studies are underway to determine how to protect the ecological role of these species, OR nega ve ecological effects from hatchery supplementa on or FADs are possible and management is not place to mi gate these impacts 2 (High Concern)—Fishery catches species that play an excep onally large role in the ecosystem and no efforts are being made to incorporate their ecological role into management. 1 (Very High Concern)—Use of hatchery supplementa on or fish aggrega ng devices (FADs) in the fishery is having serious nega ve ecological or gene c consequences, OR fishery has resulted in trophic cascades or other detrimental impacts to the food web.
75 Factor 4.1 - Impact of Fishing Gear on the Habitat/Substrate UNITED STATES / GEORGES BANK, BOTTOM LONGLINES UNITED STATES / GULF OF MAINE, BOTTOM LONGLINES Low Concern Demersal longline fisheries for haddock take place over sand and gravel seabeds in the Gulf of Maine and Georges Bank region. This is scored as "low" concern.
UNITED STATES / GEORGES BANK, HANDLINE UNITED STATES / GULF OF MAINE, HANDLINE Very Low Concern Handline or rod and reel fisheries have minimal contact with the seabed and any nega ve impacts are expected to be minimal. This is scored as "very low" concern.
UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM GILLNET Low Concern Gillnets are used to target cod and pollock, predominantly over gravel, sand, and silt habitats in inshore areas of the Northwest Atlan c. Impacts on the seabed are expected to be limited to the impact of anchors on the substrate and minimal amounts of scouring during se ng and hauling nets. This is scored as "low" concern.
UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM TRAWL Moderate Concern O er trawls, along with other forms of bo om trawl, are known to have a detrimental impact on some seabed habitats, par cularly low energy environments and biogenic reef habitats. The majority of fishing ac vity for cod, haddock, and pollock takes place in sta s cal areas 513–515, 521, 522, 525, and 561–562, with smaller amounts of fish being landed from areas 537–539 (Figure 13). These areas contain a number of seabed types, but the predominant types are sand, gravel-sand, and sand-silt/clay in waters less than 100 m deep; gravel habitats affected by trawling in this region are less than 60 m deep (Figure 12) (NEFSC 2011b) (NEFSC 2011c). These seabed types and the communi es they support are generally more resilient to trawling than deep-water biogenic reef habitats. This is scored as "moderate" concern. Ra onale:

79 UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM TRAWL
Minimal Mi ga on The altera on of marine habitats by fishing gear can be reduced through the reduc on of fishing effort or spa al closures that protect vulnerable habitats. There are a number of permanent and temporary spa al closures in place in the Gulf of Maine and Georges Bank. There are seven permanent closures in place to protect essen al fish habitat (EFH) from the impacts of bo om trawling (Figure 14), established under Amendment 13 of the mul species FMP (NEFMC 2004). There are an addi onal five year-round closures designated through the mul species FMP, along with five rolling closures in the Gulf of Maine and a seasonal closure on Georges Bank. These closures are primarily designed to protect important spawning grounds and juvenile fish. Ra onale: The requirement for fisheries management plans to minimize to the extent prac cable the adverse effects of fishing on essen al fish habitat was set forth in the Sustainable Fisheries Act of 1996 (SFA). Amendment 11 of the mul species FMP established EFH for the species covered by the plan and established areas where bo om-tending gears were to be prohibited in order to protect the marine habitats (NEFMC & NMFS 1998). To mi gate against and minimize poten al damage to EFH, the NEFMC has implemented spa al closures (Figure 19), introduced limited permit schemes, and placed restric ons on the gears that can be used when trawling (Orphanides & Magnusson 2007). In addi on to the year-round and rolling closures men oned above, there are restricted gear areas (RGAs) that provide protec on from par cular gear types; for example, the Inshore Restricted Roller Gear Area. Approximately 20% of the Georges Bank and Gulf of Maine seabed is protected from trawling ac vi es through the variety of closures, although only 9.7% of the seabed is permanently protected through EFH closures (NOAA 2013b). Framework Adjustment (FA) 48 to the mul species FMP provides sectors with the opportunity to request exemp ons to year-round fishing mortality area closures, which has raised concerns among fishing industry stakeholders and environmental groups pertaining to impacts on seabed habitat. But the rule set forth in FA48 prevents an exemp on from being made to areas that overlap with closures created to protect essen al fish habitat (Federal Register 2013).
Factor 4.3 - Ecosystem-Based Fisheries Management UNITED STATES / GEORGES BANK, BOTTOM LONGLINES UNITED STATES / GEORGES BANK, HANDLINE UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES / GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES / GULF OF MAINE, BOTTOM LONGLINES UNITED STATES / GULF OF MAINE, HANDLINE UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES / GULF OF MAINE, LARGE MESH BOTTOM TRAWL Moderate Concern
80 Collec vely, the Magnuson-Stevens Fishery Conserva on and Management Act, the Na onal Environmental Policy Act, the Endangered Species Act, the Marine Mammal Protec on Act, and the Coastal Zone Management Act require fisheries managers to take into account the impact of fishery opera ons on the ecosystem they are conducted in (NEFMC SSC 2010b). In July 2010, an Execu ve Order established the first U.S. na onal policy on the stewardship of the oceans, coasts, and Great Lakes. One of the nine na onal priori es set out in this policy is the adop on of Ecosystem-Based Management (EBM) (NEFMC SSC 2010b). The NEFMC has started the process of developing and implemen ng Ecosystem-Based Fisheries Management (EBFM). It is an cipated that the process of moving from the current management system to EBFM will take a minimum of 5 years. The current mul species FMP has elements of EBFM within it, because it already considers mul ple species rather than using the tradi onal single-species fisheries management. Moving forward, other EBFM plans will become more holis c and integrated for a given ecosystem region, such as the Western Gulf of Maine (NEFMC SSC 2010b), with predator-prey rela onships, compe on, habitat status and gear impacts, and protected species all considered under one plan. The development and implementa on of these plans is proceeding through three phases: establish goals and objec ves, iden fy management and scien fic requirements to implement EBFM in the region, and implement EBFM using quota-based management in all ecosystem produc on units.

86 Appendix A: Extra By Catch Species
Acadian redfish
Factor 2.1 - Inherent Vulnerability UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Medium FishBase provides a vulnerability score of 44 for Acadian redfish (Froese & Pauly 2012).
Factor 2.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Very Low Concern
The latest informa on available on the Acadian redfish stock in the Northwest Atlan c es mates that SSB2010 is 314,780 MT, which is higher than the SSBMSY of 238,000 MT (NEFSC 2012a). This results in a score of "very low" concern.
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Very Low Concern
Total fishing mortality in 2010 was 0.006 compared to FMSY of 0.04 (NEFSC 2012a). This results in a score of "very low" concern. Ra onale: The Acadian redfish stock was previously in a rebuilding plan and is now considered to be rebuilt, because management was successful in reaching the FREBUILD target of 0.01 set through Amendment 13 of the NE Mul FMP (NEFMC 2004). Acadian redfish is caught primarily using large mesh o er trawl (93% of landings) and gillnet (6% of landings).
Factor 2.4 - Discard Rate UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL 40-60%
87 Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b). Skate species are believed to have a higher post-release survival rate than other fish species. A recent study revealed that the post-release mortality of the skate complex (species combined) was 19%, with the highest post-release mortality exhibited by smooth skate at 60% (Mandelman et al. 2013). Because of the uncertainty about which skate species are discarded during the groundfish fishery, a precau onary assump on is made that they are all smooth skate; this results in an overall discard rate of 43%.
Ra onale: It is worth no ng that, in recent years, fishers have been adop ng more selec ve gears in an a empt to reduce bycatch of non-target, low abundance species. Separator trawls and Ruhle trawls are designed to take advantage of the different behaviors of different species: catching species such as haddock that tend to swim upward and allowing the release of species that tend to swim down during capture, such as cod and fla ish.
UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET 20-40% The main species discarded in the large mesh gillnet fishery is spiny dogfish (41.6% of total landings) (NMFS 2011b). Spiny dogfish has been shown to have a 55% overall mortality rate in gillnet fisheries (Rulifson 2007). Therefore, the overall discard rate was adjusted to account for the survival rate of spiny dogfish, resul ng in an overall discard rate of 28%.
White hake
Factor 2.1 - Inherent Vulnerability UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL High The FishBase vulnerability score for white hake is 65 (Froese & Pauly 2012).
Factor 2.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern The most recent assessment of white hake was the 56th Stock Assessment Workshop assessment in 2013, which indicated that SSB2011 = 26,877 MT and BMSY proxy = 32,400 MT; the stock was therefore not overfished, with B2011 /B MSY = 0.83 (NEFSC 2013b). This is scored as "low" concern. Ra onale:
88 The es mated spawning stock biomass has been increasing in recent years from 14,205 MT in 2007 to 26,877 MT in 2011; during this period, F has been rela vely low and recruitment has been around the long- term average. It is believed that this is a genuine increase in abundance and not the result of changing the model used to assess the state of the stock (NEFSC 2013b).
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern
The most recent assessment of white hake was the 56th SAW assessment in 2013, which indicated that F2011 = 0.130 and FMSY = 0.2 , so overfishing was not occurring, with F2011 /F MSY = 0.65 (NEFSC 2013b). Over the period 1989–2010, landings have exceeded discards by nearly 10:1, with approximately two-thirds to three- quarters of landings made by the bo om o er trawl fleet and another 20%–25% of landings from the sink gillnet fishery (NEFSC 2012a). White hake represents approximately 5% of the landings from the groundfish o er trawl fishery (NMFS 2011b). We have scored this as "low"concern.
Factor 2.4 - Discard Rate UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL 40-60% Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b).

The best es mate of abundance is 48,819, although there is a possibility that seasonal varia ons in abundance occur and future studies may improve es ma ons (Waring et al. 2016). White-sided dolphin is no longer considered a strategic stock in the Western North Atlan c because average annual human-related mortality does not exceed the PBR (Waring et al. 2016). We have awarded a "high" concern score.
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern The large mesh o er trawl was responsible for an annual average of 82 white-sided dolphin mortali es between 2009 and 2013 (Waring et al. 2016). This represents 27% of the poten al biological removal (PBR) of 304, which is not exceeded by cumula ve fishing impacts. The fishery is listed as a Category II fishery. We have awarded a "low" concern score.
UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET Very Low Concern The average es mated annual mortality rate of white-sided dolphin in the gillnet fishery was 19 between 2009 and 2013 (Waring et al. 2016). This represents 6% of the poten al biological removal (PBR) of 304, which is not exceeded by collec ve fishing ac vi es. Fishery mortality is rated as a "very low" concern.
Factor 2.4 - Discard Rate UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL 40-60% Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b).

Popula on trend analysis has not been conducted for the stock. Because abundance rela ve to a sustainable level is unknown and marine mammals are considered highly vulnerable to fishing ac vi es, abundance is considered a "high" conserva on concern.
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Very Low Concern The Western North Atlan c popula on of harbor seal is not considered a strategic stock (Waring et al. 2016). Total fishery-related mortality and serious injury from 2009 to 2013 was 408, which did not exceed PBR (2,006). A small propor on (< 1% of PBR) was a ributed to the bo om trawl fishery. We have awarded a score of "very low" concern. Ra onale: The large mesh gillnet and large mesh o er trawl are known to interact with harbor seal in the Northwest Atlan c. The average annual fishing mortality and serious injury between 2009 and 2013 that was associated with the gillnet fishery was 358, while 3.2 annually were a ributed to the bo om trawl fishery (Waring et al. 2016).

Ocean pout
Factor 2.1 - Inherent Vulnerability UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL High The FishBase vulnerability score is 67 (Froese & Pauly 2012).
Factor 2.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL High Concern
The 3-year average survey index for ocean pout in 2010 was 0.41kg/tow, which was 8% of the BMSY proxy (4.94 kg/tow) (NEFSC 2012a). This is scored as "high" concern.
95 Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Moderate Concern
The most recent assessment of ocean pout was published in 2012, which indicated F2010 = 0.31 and FMSY proxy = 0.76, so F2007 /F MSY = 0.41 and overfishing was not occurring (NEFSC 2012a). Even though catch and exploita on ra os remain at, or near, record-low levels, the stock size has not increased from its record-low level, sugges ng that it may be in a depensatory state. Discards are believed to exceed landings, due mainly to a lack of market (NEFSC 2012a), and are less than 1% of landed weight in the o er trawl and longline fisheries (NMFS 2011b). This results in a score of "moderate" concern. Ra onale: Historically, the majority of ocean pout landings have been taken using o er trawl gear; however, in 2010, o er trawl landings dropped down to less than one percent of all landings, with fish and lobster pots contribu ng over 85% of landings for the year (NEFSC 2012a). Over the period 2006 to 2010, large-mesh o er trawl fisheries also accounted for 62%–93% of ocean pout discards (NEFSC 2012a). In recent years, discards have exceeded landings, and may be sufficiently high to hinder stock recovery; nevertheless, the lack of response to reduced exploita on suggests that the stock’s dynamics have been so severely affected by historical overfishing that the stock is unlikely to rebuild, even in the absence of fishing mortality (NEFSC 2008).
Factor 2.4 - Discard Rate UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL 40-60% Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b).

96 Atlan c halibut has a FishBase vulnerability score of 88 (Froese & Pauly 2012).
Factor 2.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL High Concern
The most recent assessment of Atlan c halibut was published in 2012, and it indicated B2010 = 1,700 MT and BMSY = 49,000 MT. Therefore, the stock is not considered overfished, with B2010/BMSY = 0.0347 (NEFSC 2012c). Atlan c halibut is considered a species of concern by NMFS (NMFS 2012c). We have scored this as "high" concern.
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Moderate Concern Gulf of Maine/Georges Bank Atlan c halibut is in year 8 of a 52-year rebuilding plan (NMFS 2012c). Since 2009, NMFS also had a possession limit of one fish per trip for Atlan c halibut (NEFSC 2012a). The most recent assessment of Atlan c halibut indicated F2010 = 0.032 and FMSY = 0.0731, so F2010/FMSY = 0.438 and overfishing was not occurring (NEFSC 2012a). But FREBUILD, the target fishing pressure if the stock is to be rebuilt by 2056, is 0.044 (Col & Legault 2009); thus, although F2010/FREBUILD = 0.73, fishing mortality exceeded FREBUILD in 6 of the last 10 years for which data were available, and the average value of F for this me was 0.0504, slightly above FREBUILD (NEFSC 2012a). Also, FREBUILD is likely to be highly op mis c (see “Detailed Ra onale” below). Discards of halibut are a low propor on of the landings for all the gears assessed here (< 0.1%) (NMFS 2011b). But discards of halibut have been increasing and now outweigh landings, partly because of the increase in minimum landing size in 1999 and 2004, and the introduc on of the reten on limit (NEFSC 2012a). This factor is scored as "moderate" concern. Ra onale:
97 No directed fishery exists for halibut in federal waters, although a limited halibut fishery is permi ed in Maine’s state waters. Amendment 9 to the NE Mul species FMP permits a one-fish possession limit (NMFS 2009).
FREBUILD and the rebuilding meframe may be highly op mis c for three reasons. First, the popula on model makes the unrealis c assump on that the popula on grows at its maximum rate, even though there are currently no indica ons that this is the case. Second, the model does not incorporate age structure; thus, because the mean age of maturity for females is 7.3 years, there will be a lag me of ini al response to management measures and a slower rebuilding trajectory than projected. Third, the currently assessed Gulf of Maine-Georges Bank stock is likely a small por on of a larger U.S.-Canadian Atlan c halibut stock, because there is strong evidence that halibut is capable of long-distance movements and of crossing U.S.-Canada boundaries in substan al numbers, and this dynamic is unaccounted for by the current model (Col & Legault 2009).

Skate species are believed to have a higher post-release survival rate than other fish species. A recent study revealed that the post-release mortality of the skate complex (species combined) was 19%, with the highest post-release mortality exhibited by smooth skate at 60% (Mandelman et al. 2013). Because of the uncertainty about which skate species are discarded during the groundfish fishery, a precau onary assump on is made that they are all smooth skate; this results in an overall discard rate of 43%. Ra onale: It is worth no ng that, in recent years, fishers have been adop ng more selec ve gears in an a empt to reduce bycatch of non-target, low abundance species. Separator trawls and Ruhle trawls are designed to take advantage of the different behaviors of different species: catching species such as haddock that tend to swim upward and allowing the release of species that tend to swim down during capture, such as cod and fla ish.

Spiny dogfish has been shown to have a 55% overall mortality rate in gillnet fisheries (Rulifson 2007). Therefore, the overall discard rate was adjusted to account for the survival rate of spiny dogfish, resul ng in an overall discard rate of 28%.

It is listed as a species of special concern for the Northeast sink gillnet fishery (NMFS 2012d). This is scored as "high" concern. Ra onale: The Northeast sink gillnet fishery is listed as a Category I fishery in the 2016 LOF (List of Fisheries) because the annual mortality and serious injury to harbor porpoise stock (Gulf of Maine/Bay of Fundy) exceeds 50% of the PBR level of harbor porpoise (Waring et al. 2016).
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Very Low Concern The es mated average annual mortality of harbor porpoise in the Northeast bo om trawl fishery between 2009 and 2016 was 2.6 (Waring et al. 2016). This is less than 1% of the PBR of 706. We have awarded a score of "very low" concern.
UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET Moderate Concern The Northeast sink gillnet fishery is listed as a Category I fishery and removes more than 50% of the PBR (706) (Waring et al. 2016). Some management ac ons are in place ( me/area closures and pingers) and are believed to be effec ve. But because of low compliance with pinger requirements, the target bycatch rate was exceeded in 2011 and 2012 (NERO 2013). More recent data indicate that the PBR is no longer exceeded, and that compliance is improving. Because the current cumula ve fisheries mortality does not exceed PBR, fishery mortality is considered a "moderate" concern. Ra onale:
108 The total annual es mated average fishery-related mortality or serious injury of harbor porpoise in the Gulf of Maine and Bay of Fundy is 564, compared to a poten al biological removal (PBR) of 706. Of those instances, 521 per year are from U.S. fisheries (using observer and Marine Mammal Authoriza on Program data), with an annual average of 385.5 serious injuries and mortali es a ributable to the Northeast gillnet fishery between 2009 and 2013 (Waring et al 2016). The 1994--1998 average es mated harbor porpoise mortality and serious injury rate in the NE gillnet fishery (mesh size unspecified) was 1,163 animals per year, so there has been a decrease in serious injuries and mortali es since the introduc on of the Take Reduc on Plan. But total U.S. fishery-related mortality and serious injury for this stock exceeded the PBR, so the stock qualified as a Strategic stock. The Harbor Porpoise Take Reduc on Plan (HPTRP) was implemented in 1998 to reduce interac ons between harbor porpoise and commercial gillnet gear capable of catching mul ple species in the Gulf of Maine and Mid-Atlan c coasts (NMFS 1998). The plan includes four complete me/area closures, and me/area closures unless pingers are used (see Appendix A1). Also included in the HPTRP are historically high areas of harbor porpoise bycatch. These areas are considered "consequence closure areas" that will seasonally close if the average bycatch rates of two consecu ve management seasons are greater than the specified bycatch rate of 0.031 harbor porpoise per metric ton. If the rate is exceeded, the Coastal Gulf of Maine Consequence Closure Area will be closed during October and November to gillnet fishing (See Appendix A2; (NMFS 2010a)). These measures have decreased the average es mated harbor porpoise mortality and serious injury by 49% from 1994--1998 (before the HPTRP) to 2004--2008 (a er the HPTRP) (NMFS 2010b). Unfortunately, because of low compliance with pinger requirements, bycatch rates for the monitoring seasons in 2010--2011 (0.078) and 2011--2012 (0.043) exceeded the target rate (0.031) and prompted the area closure (NERO 2012) (NERO 2013). A er a request from the fishing industry and a review of the conserva on benefit to harbor porpoise, the area was closed from February 1–March 31, 2013 instead of October and November 2012 (NERO 2012) (NERO 2013). Recent data suggest that compliance is improving and that PBR is no longer exceeded, but the gillnet fishery is s ll contribu ng to a mortality rate greater than 50% of the PBR based on 2013 data (Waring et al. 2016) (NERO 2013) (NOAA 2013b).

In the fourth quarter of 2012, smooth skate was not experiencing overfishing (NMFS 2012c). This is scored as "low" concern.
110 Ra onale: The fishing mortality reference points for skates are based on changes in survey biomass indices. If the 3-year moving average of the survey biomass index for a skate species declines by more than the average coefficient of varia on (CV) of the survey me series, then fishing mortality is assumed to be greater than FMSY and overfishing is occurring for that skate species (Sosebee 2006).

Factor 2.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern The northern monkfish stock biomass is believed to be somewhere around the amount of 66,000 MT (NEFSC 2010), which is above the target biomass of 52,930 MT. But incomplete informa on on the life history of monkfish and a lack of discard informa on from the 1980s lead to uncertain es in the stock assessment. We have awarded a score of "low" concern. Ra onale:
112 For management purposes, the monkfish popula on in the Northwest Atlan c is divided into two stocks, northern and southern, although biological indicators suggest that the popula on is in fact one large stock (NEFSC 2010). The cod, haddock, and pollock fisheries of the Northeastern United States are likely to encounter the northern stock. Monkfish biomass es mates in both management areas are currently above BTARGET , although the stocks in the northern management area have fluctuated around that level since the late 1990s (Figure 13).

Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern
Fishing mortality for both the northern and southern stocks is below the target reference points, with F2009 at 0.1 in the north (FTHRESHOLD = 0.43) (NEFSC 2010). But there is uncertainty in the model used to assess the monkfish stock. Discarding of monkfish has decreased in recent years, and the average discard/kept ra o between 2005 and 2009 of 0.17 is close to the longterm average of 0.15 (NEFSC 2010). Monkfish discards amount to 1% of total landings in the groundfish trawl fishery (NMFS 2011b) and are not considered significant in the other gears discussed in this report. We have awarded a score of "low" concern. Ra onale:
113 Overall fishing mortality is believed to be below threshold targets in both the northern and southern stocks (Figure 14); however, there is uncertainty in the stock assessment.

Hence, winter skate is not overfished, but is currently below BMSY. Therefore, abundance is scored as “low” concern. Ra onale:
116 Biomass reference points are based en rely on NEFSC survey data because reliable landings and discard informa on are not available by species.

We have scored fishing mortality of the stock as “moderate” concern, because there is uncertainty in the biomass assessment (based on the 3-year average survey biomass) that results in unknown fishing mortality rela ve to fishing at maximum sustainable yield (FMSY). Ra onale: The fishing mortality reference points for skates are based on changes in survey biomass indices. If the 3-year moving average of the survey biomass index for a skate species declines by more than the average coefficient of varia on (CV) of the survey me series, then fishing mortality is assumed to be greater than FMSY and overfishing is occurring for that skate species (Sosebee 2015).

A recent study revealed that the post-release mortality of the skate complex (species combined) was 19%, with the highest post-release mortality exhibited by smooth skate at 60% (Mandelman et al. 2013). Because of the uncertainty about which skate species are discarded during the groundfish fishery, a precau onary assump on is made that they are all smooth skate; this results in an overall discard rate of 43%.

Separator trawls and Ruhle trawls are designed to take advantage of the different behaviors of different species: catching species such as haddock that tend to swim upward and allowing the release of species that tend to swim down during capture, such as cod and fla ish.
UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET 20-40% The main species discarded in the large mesh gillnet fishery is spiny dogfish (41.6% of total landings) (NMFS 2011b). Spiny dogfish has been shown to have a 55% overall mortality rate in gillnet fisheries (Rulifson 2007). Therefore, the overall discard rate was adjusted to account for the survival rate of spiny dogfish, resul ng in an overall discard rate of 28%.
UNITED STATES/GEORGES BANK, BOTTOM LONGLINES UNITED STATES/GULF OF MAINE, BOTTOM LONGLINES 20-40% The majority of discards from the longline fishery are skates and spiny dogfish (NMFS 2011b). There is no post-release survival informa on for this fishery (although there are ongoing studies in this area), so a discard mortality of 100% is assumed. Smaller amounts of cod and haddock are also discarded in this fishery.

In the fourth quarter of 2012, overfishing was not occurring (NMFS 2012c). We have awarded a score of "low" concern. Ra onale: The fishing mortality reference points for skates are based on changes in survey biomass indices. If the 3-year moving average of the survey biomass index for a skate species declines by more than the average coefficient of varia on (CV) of the survey me series, then fishing mortality is assumed to be greater than FMSY and overfishing is occurring for that skate species (Sosebee 2006).

Factor 2.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern In 2011, summer flounder spawning stock biomass (SSB) was es mated to be 57,020 MT, just below the target reference point of SSBMSY = SSB 35% = 60,074 MT (Terceiro 2012a); in 2010, SSB had been slightly higher than SSBMSY . As of March 29, 2012, NMFS listed Mid-Atlan c coast summer flounder as rebuilt (NMFS 2012c). We have scored abundance as "low" concern.
122 Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL High Concern The 2015 update assessment of summer flounder indicates that fishing mortality is above the fishing mortality at maximum sustainable yield (FMSY ), which means that overfishing is occurring. Fishing mortality was es mated to be 0.36 in 2014 (90% confidence interval = 0.27 to 0.44), which is 16% above the FMSY proxy of 0.31 (Terceiro 2015). The previous 2013 assessment of summer flounder indicated that overfishing on summer flounder was not occurring, but there has been a tendency in recent years to underes mate fishing mortality and to overes mate abundance (NEFSC 2013c) (Terceiro 2015). In 2014, commercial landings of summer flounder were 4,900 MT and recrea onal landings were 3,400 MT (MAFMC 2015b). An addi onal 800 MT of summer flounder were discarded at sea in the commercial fishery and 900 MT were discarded in the recrea onal fishery (Terceiro 2015). Although catches have equaled or been only slightly above the specified catch limits in recent years, there is evidence of substan al illegal and unreported fishing of summer flounder, which is likely contribu ng to the overfishing of this species (ASMFC 2015). To address the overfishing of summer flounder, managers reduced the total allowable catch by 29% for the 2016 fishing season (MAFMC 2015a). Because overfishing of summer flounder is occurring, we have awarded a "high" concern score.

Low Concern In 2010, the es mated spawning stock biomass (SSB) of American plaice was 10,805 MT, which was above the SSBTHRESHOLD of 9,199 MT but only 59% of the biomass target (SSBMSY = 18,398 MT) (NEFSC 2012a). Spawning stock biomass has been below SSBMSY since the early 1980s, but has shown an increasing trend over the last decade (Figure 16). This results in a score of "low" concern. Ra onale:

The Gulf of Maine and Georges Bank American plaice popula on is a transboundary stock; however, since the mid-1970s, 95%–100% of landings have come from U.S. fisheries (NEFSC 2012a). O er trawls account for the majority of landings of American plaice. Discards from the groundfish o er trawl fisheries are less than 1% of landings (of all species), with discards from other gears being insignificant (NMFS 2011b).

But the op mum sustainable popula on (OSP) has not been calculated for this stock, so it is not possible to determine whether the current popula on is at a sustainable level. Bo lenose dolphin is not considered to be an endangered or threatened species (NMFS 2008). This factor is scored as "high" concern.
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET Very Low Concern Mean annual mortality from 2009 to 2013 for the Northeast sink gillnet fishery is 5.2 and for the Northeast bo om trawl is 6.4 (Waring et al. 2016). Mortality from each fishery is <10% of PBR (561), and the cumula ve fishery mortality does not exceed PBR; thus, fishery mortality is rated as a "very low" concern.

We have scored this as "very high" concern. Ra onale: The best available abundance es mate for fin whale in the North Atlan c is 1,618 individuals (Waring et al. 2016). There is insufficient informa on available to assess trends in this popula on.
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET Low Concern The large mesh gillnet fishery is the only fishery within the scope of this report that is known to interact with fin whale in the Northwest Atlan c (NMFS 2012d). The poten al biological removal (PBR) for fin whale is 2.5 whales per year (Waring et al. 2016). Between 2009 and 2013, minimum annual human-caused mortali es and serious injury to fin whales from entanglement was 1.75 per year, with 0.95 occurring in the U.S. (38% of PBR). Entanglement could not be a ributed to a par cular fishery. Cumula ve fishery mortality does not exceed the PBR, thus fishery mortality is considered a "low" concern.

In the fourth quarter of 2012, NMFS considered there to be no overfishing occurring on barndoor skate in the Northwest Atlan c (NMFS 2012c). We have awarded a score of "low" concern. Ra onale: The fishing mortality reference points for skates are based on changes in survey biomass indices.

Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GEORGES BANK, BOTTOM LONGLINES UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, BOTTOM LONGLINES UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET Low Concern The 2008–2010 average survey index of 1.10 kg/tow was not 40% lower than the 2007–2009 average of 1.16 kg/tow, so NMFS did not consider overfishing to be occurring (NEFMC 2012). In the fourth quarter of 2012, overfishing was not occurring on the clearnose skate popula on (NMFS 2012c). This factor is scored as "low" concern. Ra onale:
136 The fishing mortality reference points for skates are based on changes in survey biomass indices. If the 3-year moving average of the survey biomass index for a skate species declines by more than the average coefficient of varia on (CV) of the survey me series, then fishing mortality is assumed to be greater than FMSY and overfishing is occurring for that skate species (Sosebee 2006).
Factor 2.4 - Discard Rate UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM GILLNET UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM GILLNET 20-40% The main species discarded in the large mesh gillnet fishery is spiny dogfish (41.6% of total landings) (NMFS 2011b). Spiny dogfish has been shown to have a 55% overall mortality rate in gillnet fisheries (Rulifson 2007). Therefore, the overall discard rate was adjusted to account for the survival rate of spiny dogfish, resul ng in an overall discard rate of 28%.
UNITED STATES/GEORGES BANK, BOTTOM LONGLINES UNITED STATES/GULF OF MAINE, BOTTOM LONGLINES 20-40% The majority of discards from the longline fishery are skates and spiny dogfish (NMFS 2011b). There is no post-release survival informa on for this fishery (although there are ongoing studies in this area), so a discard mortality of 100% is assumed. Smaller amounts of cod and haddock are also discarded in this fishery.
UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL 40-60% Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b). Skate species are believed to have a higher post-release survival rate than other fish species. A recent study revealed that the post-release mortality of the skate complex (species combined) was 19%, with the highest post-release mortality exhibited by smooth skate at 60% (Mandelman et al. 2013). Because of the uncertainty about which skate species are discarded during the groundfish fishery, a precau onary assump on is made that they are all smooth skate; this results in an overall discard rate of 43%. Ra onale: It is worth no ng that, in recent years, fishers have been adop ng more selec ve gears in an a empt to reduce bycatch of non-target, low abundance species. Separator trawls and Ruhle trawls are designed to take advantage of the different behaviors of different species: catching species such as haddock that tend to swim upward and allowing the release of species that tend to swim down during capture, such as cod and fla ish.
137 Winter flounder: Gulf of Maine Factor 2.1 - Inherent Vulnerability UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Winter flounder (a.k.a. blackback) has a FishBase vulnerability score of 34 (Froese & Pauly 2012).
Factor 2.2 - Abundance
UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Moderate Concern Based on the most recent assessment of Gulf of Maine blackback in 2015, the stock biomass of fish larger than 30 cm is B2014 = 4,655 MT (NEFSC 2015b). But the Stock Assessment Review Commi ee (SARC) rejected the analy cal model, and a biomass reference point could not be es mated, leaving the stock status unknown (NEFSC 2011) (NEFSC 2015). As of December 31, 2015, NMFS listed Gulf of Maine blackback as not undergoing overfishing (NMFS 2015c). Because of the unknown stock status, we have scored abundance as "moderate" concern.
Factor 2.3 - Fishing Mortality
UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern The most recent assessment of Gulf of Maine blackback in 2015 indicated that the exploita on rate in 2014 was 0.06, which is 26% of the overfishing exploita on threshold proxy (EMSY proxy = 0.23) (NEFSC 2015) (NMFS 2015c). As of December 31, 2015, NMFS listed Gulf of Maine blackback as having an “unknown” fishing mortality (NMFS 2015c). Even though it is highly likely that fishing mortality is at or below a sustainable level and will not reduce stock produc vity, a score of "low" concern has been chosen because of the NMFS lis ng. Ra onale: A proxy value of the overfishing threshold was derived from a length-based yield per recruit analysis that assumes all fish above 30 cm are fully recruited to the fishery and that natural mortality is 0.3.
Factor 2.4 - Discard Rate
UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL 40-60% Discards from the large mesh o er trawl fishery largely consist of skate species and spiny dogfish (NMFS 2011b).

High Seafood Watch considers all marine mammals to have a high vulnerability to fishing pressure (Seafood Watch 2013).
140 Factor 2.2 - Abundance UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL
High Concern The best available es mate of abundance in the western North Atlan c is 5,636 (Waring et al. 2016). Because of uncertainty regarding popula on trends and this species' high inherent vulnerability, abundance is rated as a "high" concern.
Factor 2.3 - Fishing Mortality UNITED STATES/GEORGES BANK, LARGE MESH BOTTOM TRAWL UNITED STATES/GULF OF MAINE, LARGE MESH BOTTOM TRAWL Low Concern The cumula ve average fishery-related mortality or serious injury from 2008 to 2012 was 35 individuals, which did not exceed the poten al biological removal (PBR) of 199 (Waring et al. 2016). The Northeast bo om trawl fishery was responsible for 31 of those incidents (15.6% of PBR). The stock is not considered strategic, thus fishery mortality is considered a "low" concern.

143 Appendix C: Update Summary This report was updated in July 2016 to note the status change of haddock in the Gulf of Maine which is no longer subject to overfishing. Fishery mortality concern was changed to low concern for this stock. The thorny skate was also updated to reflect that it is no longer subject to overfishing. Fishery mortality scores for thorny skate and winter skate were updated based on recent stock status updates. Stock abundance and fishing mortality scores were updated for winter flounder (blackback) and summer flounder to reflect recent stock assessment informa on resul ng in a downgrade for these scores. All marine mammals were updated with the latest stock assessment informa on from 2015. Stock status sec ons for cod and pollock were not updated because there were no status changes.
