Amendment 1 to the Interstate Fishery Management Plan for Atlantic Menhaden Fishery Management Report No. 37 of the Atlantic States Marine Fisheries Commission Amendment 1 to the Interstate Fishery Management Plan for Atlantic Menhaden July 2001 Fishery Management Report No. 37 of the ATLANTIC STATES MARINE FISHERIES COMMISSION Amendment 1 to the Interstate Fishery Management Plan for Atlantic Menhaden July 2001 Amendment 1 to the Interstate Fishery Management Plan for Atlantic Menhaden Prepared by Atlantic States Marine Fisheries Commission Atlantic Menhaden Plan Development Team Plan Development Team Members: Dr. Joseph C. Desfosse (ASMFC, Chair), Dr. Michael Armstrong (Massachusetts Division of Marine Fisheries), Ellen Cosby (Virginia Marine Resources Commission), Peter Himchak (New Jersey Division of Fish & Wildlife), Dr. John Merriner (National Marine Fisheries Service), Dr. Alexei Sharov (Maryland Department of Natural Resources) and Michael W. Street (North Carolina Division of Marine Fisheries). This Amendment was prepared under the guidance of the Atlantic States Marine Fisheries Commission’s Atlantic Menhaden Management Board, Chaired by Mr. William Pruitt of the Virginia Marine Resources Commission. Technical assistance was provided by the Atlantic Menhaden Advisory Committee, the ad hoc Atlantic Menhaden Stock Assessment Committee and the NMFS Population Dynamics Team. This is a report of the Atlantic States Marine Fisheries Commission pursuant to U.S. Department of Commerce, National Oceanic and Atmospheric Administration Award Nos. NA97FG0034, NA07FG0024 and NA17FG1050. EXECUTIVE SUMMARY 1. Introduction Concern over a real and/or perceived decline in the Atlantic menhaden population, plus the ecological importance of menhaden, led the Atlantic Menhaden Management Board to recommend that ASMFC conduct an external peer review of the menhaden stock assessment. The peer review was completed in November 1998 and provided recommendations for improving the assessment and management of menhaden (ASMFC 1999). Upon receiving the report of the Peer Review Panel in January 1999, the Board recommended that a full amendment to the current FMP be developed, and that the recommendations of the Peer Review Panel be addressed through the development of this amendment. Members of the public have also expressed concern over the composition of the Management Board, where only some of the Atlantic coast states were represented while including industry representatives as members. This amendment addresses these issues along with a number of management measures and sets up a process for the future management of Atlantic menhaden pursuant to the requirements of the Atlantic Coastal Fisheries Cooperative Management Act (ACFCMA 1993). Amendment 1 also adopts a new overfishing definition by which the Management Board shall measure the status of the resource. In addition, Amendment 1 requires mandatory reporting from all menhaden purse seine fisheries. 2. Goals, Objectives, Management Unit, Overfishing Definition Amendment 1 to the Interstate Fishery Management Plan for Atlantic Menhaden completely replaces all previous Commission management plans for Atlantic menhaden. The goal of Amendment 1 is: C To manage the Atlantic menhaden fishery in a manner that is biologically, economically, socially and ecologically sound, while protecting the resource and those who benefit from it. In support of this goal, the following objectives are recommended for Amendment 1: Biological Objectives < Protect and maintain the Atlantic menhaden stock at levels to maintain viable fisheries and the forage base with sufficient spawning stock biomass to prevent stock depletion and guard against recruitment failure. < Maintain a uniform data collection system for the reduction fishery and develop new protocols for other harvesting sectors, including biological, economic, and sociological data (ACCSP protocols as a minimum; NMFS reduction fishery monitoring system should be continued). < Evaluate, develop, and improve approaches or methodologies for stock assessment including fishery- independent surveys and variable natural mortality at age or by area. < Optimize utilization of the resource within the constraints imposed by distribution of the resource, available fishing areas, and harvest capacity. Social/Economic Objectives < Maintain existing social and cultural features of the fishery to the extent possible. < Develop a public information program for Atlantic menhaden, including the fishery, biology, estuarine ecology and role of menhaden in the ecosystem. Ecological Objectives < Protect fishery habitats and water quality in the nursery grounds to insure recruitment levels are adequate to support and maintain a healthy menhaden population. < Improve understanding of menhaden biology, food web ecology and multispecies interactions that may bear upon predator-prey and recruitment dynamics. < Protect and maintain the important ecological role Atlantic menhaden play along the coast. Management Objectives < Insure adequate accessibility to fishing grounds. < Develop options or programs to control or limit effort, and regulate fishing mortality by time or area. < Base regulatory measures upon the best available scientific information and coordinate management efforts among the various political entities having jurisdiction over the fisheries. ii Management Unit/Area The management unit for Amendment 1 is defined as the Atlantic menhaden resource throughout the range of the species within U.S. waters of the northwest Atlantic Ocean from the estuaries eastward to the offshore boundaries of the EEZ. The management area for Amendment 1 shall be the entire coastwide distribution of the resource. Overfishing Definition A target and threshold approach will be used to define stock status of Atlantic menhaden incorporating both fishing mortality and spawning stock biomass reference points. The Management Board has adopted Fmax (F = 1.04) and Frep (F = 1.33) as the fishing mortality target and threshold, respectively, for the Atlantic menhaden overfishing definition. Furthermore, the Board has adopted a spawning stock biomass target of 37,400 mt (as a proxy for BMSY) and a spawning stock biomass of 20,570 mt as the threshold level, or Minimum Spawning Stock Threshold (MSST). 3. Monitoring Program Specifications/Elements An Atlantic menhaden stock assessment will be performed on an annual basis by the stock assessment subcommittee. The technical committee and advisory panel will meet to review the stock assessment and all other relevant data sources. An annual report will be presented to the Management Board in a timely fashion (usually May or June depending on Commission meeting week scheduling) in order to make annual adjustments to the management program as necessary. In addition to the general content of the report as specified in the outline, the stock assessment report will also contain information on age/size structure, recruitment, spawning stock biomass, fishing mortality rates, catch and landings data and fishery-independent surveys. 4. Management Program Elements/Implementation Recreational Fishery Management Measures (4.1) No recreational fishery management measures are contained in Amendment 1. Recreational landings of Atlantic menhaden for bait are currently believed to be very small; therefore, regulation of this fishery is unnecessary at this time. Evaluation of the extent of this harvest is needed. Commercial Fishery Management Measures (4.2) Amendment 1 does not implement specific commercial fishery management measures to control the harvest of menhaden or limit effort in the fisheries at this time. This amendment does set up a process for implementing future management measures through addenda prepared under Adaptive Management (Section 4.6). The Management Board will review the status of the resource in relation to the overfishing definition and decide whether additional measures are required to meet the goal and objectives of this plan. Habitat Measures (4.4) No mandatory measures related to habitat or habitat protection are implemented through this amendment. De minimis Fishery Guidelines (4.5.3) The ASMFC Interstate Fisheries Management Program Charter defines de minimis as “a situation in which, under existing condition of the stock and scope of the fishery, conservation, and enforcement actions taken by an individual state would be expected to contribute insignificantly to a coastwide conservation program required by a Fishery Management Plan or amendment.” As future management measures are implemented through addenda prepared subsequent to Amendment 1, a state may be granted de minimis status if, the Management Board determines that action by the state would contribute insignificantly to the overall management program. States may petition the Atlantic Menhaden Management Board at any time for de minimis status. Once de minimis status is granted, designated states must submit annual reports to the Management Board justifying the continuance of de minimis status. States must include de minimis requests as part of their annual compliance reports. iii Recommendations to the Secretaries (4.9) The Atlantic States Marine Fisheries Commission believes that the measures contained in Amendment 1 are necessary to prevent the overfishing of the Atlantic menhaden resource. Due to the preponderance of the Atlantic menhaden resource occurring in state waters, the Commission through Amendment 1, recommends to the Secretary of Commerce that no additional management measures be implemented in federal waters at this time. In addition, Amendment

We provide these technical reports as research summaries only-they are not intended to be used in place of sound medical advice by a licensed health care practitioner. The Point Institute Director: Thomas Guilliams Ph.D. Website: www.pointinstitute.org Email: [email protected] The Point Institute www.pointinstitute.org Choosing the Best Marine-derived Omega-3 Products for Therapeutic Use: An Evaluation of the Evidence There is overwhelming data to recommend a wide range of therapeutic uses for marine-derived omega-3 fatty acids (primarily EPA and DHA). Likewise, there are also an overwhelming number of different forms, sources and ways to deliver these omega-3 fatty acids; which unfortunately, has led to confusion in product selection for both clinician and patient alike. We will walk through the most common issues discussed in selecting the appropriate omega-3 fatty acid product, with the goal to bring clarity to the decision-making process. For the most part, the marine omega-3 fatty acid category is dominated by products that can be best described as “fish oil.” That is, while there are products available that deliver omega-3 fatty acids from other marine sources, nearly all the available research has been done with fish oil derived fatty acids. This fish oil data has become the benchmark for efficacy and safety, and is the standard to which we compare throughout this paper.

  • Our Nation's Fisheries Will Be a Lot Easier Once We've Used up Everything Except Jellyfish!
    Mismanaging Our Nation’s Fisheriesa menu of what's missing Limited quantity: get ‘em while supplies last Ted Stevens Alaskan Surprise Due to years of overfishing, we probably won’t be serving up Pacific Ocean perch, Tanner crab, Greenland turbot or rougheye rockfish. They may be a little hard to swallow, but Senator Stevens and the North Pacific Council will be sure to offer last minute riders, father and son sweetheart deals, record-breaking quotas, industry-led research, conflicts of interest and anti-trust violations. Meanwhile, fur seals, sea lions and sea otters are going hungry and disappearing fast. Surprise! Pacific Rockfish: See No Fish, Eat No Fish Cowcod, Canary Rockfish and Bocaccio are just three examples of rockfish managed by the Pacific Council that are overfished. As for the exact number of West Coast groundfish that are overfished, who knows? Without surveys to tell them what’s going on, what are they managing exactly? Striped Bass: Thin Is In! This popular Atlantic rockfish is available in abundance. Unfortunately, many appear to be undernourished and suffering from lesions – a condition that may point to Omega Protein’s industrial fishery of menhaden, the striper’s favorite prey species. Actually, you may want to hold off on this one until ASMFC starts regulating menhaden. Can you believe there are still no catch limits? Red Snapper Bycatch Platter While we are unable to provide full-size red snapper, we offer this plate of twenty juvenile red snapper discarded as bycatch from a Gulf of Mexico shrimp trawler for your dining pleasure. Shrimpers take and throw away about half of all young red snappers along the Texas coast, so we’ll keep these little guys coming straight from the back of the boat to the back of your throat! Caribbean Reef Fish Grab Bag What’s for dinner from the Caribbean? Who knows? With coral reefs in their jurisdiction, you would expect the Caribbean Council to be pioneering the ecosystem-based management approach and implementing the precautionary principle approach.

  • Review of Atlantic Menhaden Ecological Reference Points
    Review of Atlantic Menhaden Ecological Reference Points Steve Cadrin July 27 2020 The Science Center for Marine Fisheries (SCeMFiS) requested a technical review of analyses being considered by the Atlantic States Marine Fisheries Commission (ASMFC) to estimate ecological reference points (ERPs) for Atlantic menhaden by applying a multispecies model (SEDAR 2020b). Two memoranda by the ASMFC Ecological Reference Point Work Group and Atlantic Menhaden Technical Committee were reviewed: • Exploration of Additional ERP Scenarios with the NWACS-MICE Tool (April 29 2020) • Recommendations for Use of the NWACS-MICE Tool to Develop Ecological Reference Points and Harvest Strategies for Atlantic Menhaden (July 15 2020) Summary • According to the SEDAR69 Ecological Reference Points report, the multi-species tradeoff analysis suggests that the single-species management target for menhaden performs relatively well for meeting menhaden and striped bass management objectives, and there is little apparent benefit to striped bass or other predators from fishing menhaden at a lower target fishing mortality. • Revised scenarios of the SEDAR69 peer-reviewed model suggest that results are highly sensitive to assumed conditions of other species in the model. For example, reduced fishing on menhaden does not appear to be needed to rebuild striped bass if other stocks are managed at their targets. • The recommendation to derive ecological reference points from a selected scenario that assumes 2017 conditions was based on an alternative model that was not peer reviewed by SEDAR69, and the information provided on alternative analyses is insufficient to determine if it is the best scientific information available to support management decisions. • Considering apparent changes in several stocks in the multispecies model since 2017, ecological reference points should either be based on updated conditions or long-term target conditions.

MCHUGH Office of Marine Resources U.S. Department of the Interior, Washington, D.C. INTRODUCTION The rise and fall of the North American Pacific coast sardine fishery is well known. Oilce the most important fishery in the western hemisphere in weight of fish landed, it now produces virtually nothing. The meal and oil industry based on the Pacific sardine (Sardinoljs caerulea) resource no longer exists. The sardine fishery (Fig. 1A) began in 1915, rose fairly steadily to its peak in 1936 (wit11 a dip during the depression), maintained an average annual catch of more than 500 000 tons until 1944, then fell off sharply. Annual production has not exceeded 100 000 tons since 1951, and commercial sardine fishing now is prohibited in California waters. A much smaller fishery for the southern sub-population developed off Baja California in 195 1. The decline of the west coast sardine fishery gave impetus to the much older menhaden (Breuoortia tyranlzus) fishery (Fig. 1B) along the Atlantic coast of the United States. Fishing for Atlantic menhaden began early in the nineteenth century. From the 1880's until the middle 1930's the annual catch varied around about 200 000 tons. In the late 1930's annual landings began to increase and from 1953 to 1962 inclusive re- mained above 500 000 tons. The peak year was 1956, with a catch of nearly 800 000 tons. After 1962 the catch began to fall off sharply, reach- ing a low of less than 250 000 tons in 1967.

  • Us Fishery Production in 1946
    FISH ANDWILDLIFE SERVICE I For Release to PM's TUESDAY,JANUARY 14, 1947. U. S. FISHERYPRODUCTION y 1946 / In 1946 the little known menhaden became the major item in the United States . \ fish catch, which totaled 4.2 billion pounds, the Fish and Wildlife Service, I United States Department of-the Interior, announced today. The menhaden, an Atlantic coast fish used chiefly in the manufacture of fish _- . meal and oil, replaced the Pacific pilchard or sardine which has supported the Nation's largest fishery for the past 12 years, Although the 1946 production was not far bekwu average in volume, the year was marked by extremes of success or failure almost without parallel in the history of the fisheries. Rosefish and tuna exceeded all previous production records; the _ < salmon pack was the smallest since 1927; the menhaden catch was the largest on record; the pilchard fishery experienced the worst season in its history. In terms of pounds landed, the leading fisheries last year were menhaden, . 4 pilchard,._ salmon, tuna, Alaska herring, and rosefish. These six accounted for more than half of the total production. The Fish and Wildlife Service reported that the catch of menhaden was approx- . I s . imately 900,000,000 pounds, compared with 756,000,OOO pounds in 1945 and . 686;ooojooo in 1944. The menhaden, which has supported a fishery since colonial I times, is a schooling fish of the herring family which occurs in tremendous numbers . along the Atlantic coast and in its bays and estuaries. Present centers of the menhaden industry are Lewes, Del,, Reedville, Va,, ,Port M&mouth, N.

  • UNITED STATES FISH CATCH SHOWS GAIN--August 8, 1961
    Wells - Int. 4817 Luzlxmu~EMU@IF UMB OMUBW ll@W INFORMATION SERVICE FISH ANDWILDLIFE SERVICE For Release AUGUST8, 1961 UNITEDSTATES FISH CATCHSHOWS GAIN The United States' catch of fish and shellfish during the first six months of 1961 totaled about 1,692,400,000 pounds-- up24lmillion pounds over the same period a year ago--a aain of 17 percent, the Department of the Interior reported today. Gains were recorded in landings of menhaden, tuna, salmon, haddock, ocean perch, Pacific mackerel, and scallops while declines were noted for jack mackerel, whiting and shrimp, data compiled by the Bureau of Commercial Fisheries of the Fish and Wildlife Service revealed. The data were based largely on figures for six months or more but, in a few instances, reports were for a shorter period. The biggest incrcaase was in menhaden landings-- 227 million pounds more than for the first six months of last year. This year's market for fiah.maal, one of the products from menhaden, is improved over a year ago, resulting in an increased fishing effort which has brought about this gain. Tuna landings in California showed a gain of 16 million pounds up to July 15. Most of this is largely the result of a 3%million pound increase in the catch by purse seiners. In Alaska, the Bristol Bay red salmon catch was a 5-year-age class of much bigger fish than a year ago. Last year, it took 15 to 16 fish to fill a case. This year it was done with 11 to 12. As a result, the Alaska salmon catch was 4 million pounds above a year ago.

We have formatted it as a report. It includes a Preface, which sets the stage, an Executive Summary without citations, and a response to each of the questions with supporting citations. We have enclosed a copy of the paper (Condrey 1994) we believe was used by TPWD in drafting the proposed regulations. It has the appropriate underlying numbers and is the only study with sufficient detail to be used for the type of analysis attempted by TPWD. We appreciate the opportunity to provide this analysis. It came at an opportune time. I have been developing the ecosystem material included in this document for many years, ever since the basic theory was proposed to me by a Russian colleague who went on to become the Soviet Minister of Fisheries. As Chief of the NMFS Research Division, I read countless documents regarding fisheries research and management, and attended many conferences and program reviews, slowly gaining the knowledge reflected in this report. The flurry of menhaden writings and government actions gave me impetus to complete the work, and your request accelerated it further. I expect the ecosystem materials in this present report will soon be part of a more- detailed formal scientific paper documenting the role of menhaden in coastal ecology.

On average5.4 fish/day were deliveredto the nests. The size of fish deliveredranged from 4 to 43 cm, and the mean weight of fish deliveredwas 156.9 g. Atlantic Menhaden (Brevortiatyrannus) accounted for nearly 75% of the diet, although White Perch (Motone americana),Atlantic Croaker (Micropogoniasundulatus), Oyster Toadfish (Opsanustau), and American Eel (Anguilla rostrata)also were commonprey. ChesapeakeBay Ospreys,estimated at 3000 breedingpairs, would be expectedto eat about 132 171 kg of fish during the 52-day nestlingperiod. This "harvest"represents 0.004% of the annual ChesapeakeBay commercialharvest and likely has a minimal impact on the local fishery.
