Framework Adjustment 6 to the Northeast Skate Complex FMP Framework Adjustment 6 To the Northeast Skate Complex FMP Prepared by the New England Fishery Management Council in cooperation with the National Marine Fisheries Service New England Fishery Management Council 50 Water Street Newburyport, MA 01950 Initial Framework Meeting: January 30 2018 Final Framework Meeting: Preliminary Submission: Final Submission: Executive Summary 1.0 Executive Summary In New England, the New England Fishery Management Council (NEFMC) is charged with developing management plans that meet the requirements of the Magnuson-Stevens Act (MSA). The Northeast Skate Complex Fishery Management Plan (FMP) specifies the management measures for seven skate species (barndoor, clearnose, little, rosette, smooth, thorny and winter skates) off the New England and Mid- Atlantic coasts. The FMP has been updated through a series of amendments, framework adjustments and specification packages. Amendment 3 to the FMP established a control rule for setting the Skate acceptable biological catch (ABC) based on survey biomass indices and median exploitation ratios; the ABC was set to equal the annual catch limit (ACL). This framework adjustment would implement changes to specifications based on updated data and research and would add a new seasonal allocation of the skate wing fishery TAL. The need for this action is to meet regulatory requirements and adjust management measures that are necessary to prevent overfishing, ensure rebuilding, and help achieve optimum yield in the fishery consistent with the status of stocks and the requirements of MSA of 2006, and to provide flexibility for vessels fishing in the NAFO Regulated Area to maximize skate retention and to land skate in the US. There are several purposes: to adopt fishing specifications for FY 2018 and FY 2019 for skates, to develop a possession limit for barndoor skate based on updated stock information, and to minimize regulatory obstacles, through exemptions, for vessels utilizing the US quota of groundfish and other species in the NRA. Proposed Action Under the provision of the MSA, the Council submits proposed management actions to the Secretary of Commerce for review. The Secretary of Commerce can approve, disapprove, or partially approve the action proposed by the Council. In the following alternative descriptions, measures identified as Preferred Alternatives constitute the Council’s proposed management action. If the Preferred Alternatives identified in this document are adopted, this action would implement a range of measures designed to achieve mortality targets and net benefits from the fishery. Details of the measures summarized below can be found in Section 4.0. The Preferred Alternatives include: • Modification to the Uncertainty Buffer Summary of Environmental Consequences The environmental impacts of all of the alternatives under consideration are described in detail in Section 7.0. Biological Impacts Essential Fish Habitat (EFH) Impacts Impacts on Endangered and Other Protected Species Socio-Economic Impacts Framework 3 6 Executive Summary Alternatives to the Proposed Action If the Proposed Action is based on the Preferred Alternatives there are a number of alternatives that would not be adopted. These alternatives are briefly described below. • Modification to the Uncertainty Buffer o Reduction in the Uncertainty Buffer Alternatives.

  • Spatial Ecology and Fisheries Interactions of Rajidae in the Uk
    UNIVERSITY OF SOUTHAMPTON FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences SPATIAL ECOLOGY AND FISHERIES INTERACTIONS OF RAJIDAE IN THE UK Samantha Jane Simpson Thesis for the degree of DOCTOR OF PHILOSOPHY APRIL 2018 UNIVERSITY OF SOUTHAMPTON 1 2 UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences Doctor of Philosophy FINE-SCALE SPATIAL ECOLOGY AND FISHERIES INTERACTIONS OF RAJIDAE IN UK WATERS by Samantha Jane Simpson The spatial occurrence of a species is a fundamental part of its ecology, playing a role in shaping the evolution of its life history, driving population level processes and species interactions. Within this spatial occurrence, species may show a tendency to occupy areas with particular abiotic or biotic factors, known as a habitat association. In addition some species have the capacity to select preferred habitat at a particular time and, when species are sympatric, resource partitioning can allow their coexistence and reduce competition among them. The Rajidae (skate) are cryptic benthic mesopredators, which bury in the sediment for extended periods of time with some species inhabiting turbid coastal waters in higher latitudes. Consequently, identifying skate fine-scale spatial ecology is challenging and has lacked detailed study, despite them being commercially important species in the UK, as well as being at risk of population decline due to overfishing. This research aimed to examine the fine-scale spatial occurrence, habitat selection and resource partitioning among the four skates across a coastal area off Plymouth, UK, in the western English Channel. In addition, I investigated the interaction of Rajidae with commercial fisheries to determine if interactions between species were different and whether existing management measures are effective.

  • Stock Assessment and Fishery Evaluation of Skate Species (Rajidae)
    16. Gulf of Alaska Skates by Sarah Gaichas1, Nick Sagalkin2, Chris Gburski1, Duane Stevenson1, and Rob Swanson3 1NMFS Alaska Fisheries Science Center, Seattle WA 2ADF&G Commercial Fisheries Division, Kodiak AK 3NMFS Alaska Fisheries Science Center, Kodiak AK Executive Summary Summary of Major Changes Changes in the input data: 1. Total catch weight for GOA skates is updated with 2004 and partial 2005 data. 2. Biomass estimates from the 2005 GOA bottom trawl survey are incorporated. 3. Life history information has been updated with recent research results. 4. Information on the position of skates within the GOA ecosystem and the potential ecosystem effects of skate removals are included. Changes in assessment methodology: There are no changes to the Tier 5 assessment methodology. Changes in assessment results: No directed fishing for skates in the GOA is recommended, due to high incidental catch in groundfish and halibut fisheries. Skate biomass changed between the last NMFS GOA trawl survey in 2003 and the most recent survey in 2005, which changes the Tier 5 assessment results based on survey biomass. The recommendations for 2005 based on the three most recent survey biomass estimates for skates and M=0.10 are: Western Central GOA Eastern GOA GOA (610) (620, 630) (640, 650) Bathyraja skates Gulfwide Big skate ABC 695 2,250 599 ABC 1,617 OFL 927 3,001 798 OFL 2,156 Longnose skate ABC 65 1,969 861 OFL 87 2,625 1,148 Responses to SSC Comments SSC comments specific to the GOA Skates assessment: From the December, 2004 SSC minutes: The SSC is grateful to samplers with ADF&G who collected catch data and biological samples for Kodiak landings.

  • Case Reports for Species & Habitats on the Initial Draft
    OSPAR Commission, 2008: Case reports for the OSPAR List of Threatened and/or Declining Species and Habitats ___________________________________________________________________________________________________ Nomination Decline Dipturus (Raja) batis, Common Skate The Common Skate has declined throughout its range. The magnitude of decline is differentially well documented in various areas, but it is known to have severely declined in most shelf areas (ICES, 2002). For example, D.batis has been commercially extinct in the Irish Sea for some years (Brander, 1981) and has declined severely in the North Sea (Walker & Hislop, 1998). This skate was once an abundant constituent of the demersal fish community of north-west Europe. Fisheries data indicate that populations of Dipturus batis have undergone an extremely high level of depletion in the central part of its range around the British Isles since the early part of this century. Although landings appear stable in other parts of the species’ range, this is attributed to the redirection of fishing effort from shelf seas, where populations have been very heavily depleted, into deeper water where previously unfished populations are now being taken (Ellis & Walker, in press). Catch statistics reveal a major decline in landings of th all skates and rays since the beginning of the 20 century but there are some difficulties with interpretation at the species level, as the data have sometimes been combined. There are some Geographical extent records, however, that distinguish between catches OSPAR Regions; All of the different species such as the Scottish Biogeographic zones: 1,2,4,6-9,11-14 sampling programme carried out in the North Sea Region & Biogeographic zones specified for decline between 1929-1956 and 1981-1995.

  • EC Dipturus Species
    9.3.2.4 Special request, Advice October 2012 ECOREGION Widely distributed and migratory stocks SUBJECT European Commission special request on spatial distribution, stock status, and advice on Dipturus species Advice summary The larger Dipturus cf. intermedia occurs in the northern North Sea and off the northwest coast of Scotland, and D. cf. flossada is the predominant species in the Celtic Sea and around Rockall. The two species overlap over a wide part of the Celtic seas ecoregion. There are insufficient data to delineate the more southerly and offshore distributional limits of the two species. In the North Sea, Celtic seas, and the Bay of Biscay and Atlantic Iberian waters, the Dipturus complex is considered to be depleted. Advice in each area is that there should be no targeted fishery for either Dipturus cf. flossada or Dipturus cf. intermedia, based on the precautionary approach for data-limited stocks, and measures should be taken to minimize bycatch. Additional measures should be identified that can regulate exploitation of the complex. Such measures may include seasonal and/or area closures, technical measures, and tailored measures for target fisheries. Such measures should be developed by stakeholder consultations, considering the overall mixed fisheries context. Information on identification is provided to enable fishers, port staff, and enforcers to separate the two species. Request Dipturus batis, the common skate, is now considered to consist of two species. Dipturus cf. flossada and Dipturus cf. intermedia are considered to form part of the Dipturus complex. According to its depleted situation (stock described in scientific papers as the first clear case of a fish species brought to the brink of extinction by commercial fishing), there is an existing management scheme as for Dipturus batis, mainly a ban on landing.

  • The Common Skate and the Spurdog
    Following Scotland’s Sharks: The common skate and the spurdog James Thorburn Thank you’s This project could not have happened if it were not for the support and help of many people: Knox Marine services, Ronnie Campbell, Roger Eaton, Inverlussa staff, Ian Burrett, Derek Bailey, David Isaacs, Gordon Shearer, Lismore Seafoods, Jake Crossley, David Morris and Rob Main, Colin Currie, Simon Exley, Lea-Anne Henry, Calmac, Scottish Sea Farms, the anglers and fishermen who have returned tags and receivers to us What’s it all about!? “Conserving and managing Scottish elasmobranch’s effectively” How!? Fisheries – management options • Total Allowable catch • Prohibition • Real time closure Species specific legislation • Wildlife and Countryside Act 1981 • Basking Shark • CITES ( Convention on International Trade in Endangered Species ) • Appendices 1 & 2 Marine Protected Areas • A designated spatial area with some form of management • Only really of use in areas with strong philopatric behaviour • Residential • Return • Generally only protect one age/sex class at a time • Thought to be most suitable for critical life stages • Protection of nursery areas highly prioritised Elasmobranch nursery grounds • Protected areas • Coastal • Estuaries • Shallow bays • Reefs inc. deep water Home range Size/Age of Shark Elasmobranch nursery grounds • Protection of nursery grounds prioritised, taken from teleost (bony fish) management such as cod. • The increase in home range as a shark grows often means the move out of the protected areas as they get bigger • Late maturity (up to 15 years of age) means that the sharks may spend a large proportion of their life unprotected. Late maturity means sharks may be fished before they reproduce – no nursery anymore Adult MPAs Some behaviours promote the suitability of MPAs for adult sharks: • Site fidelity; repeated use of same area • Residency; remaining within an area for large amounts of time.
