Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the Alaska Department of Fish and Game large-mesh bottom trawl survey is to estimate abundance of Tanner crab, Chionoecetes bairdi, and biomass of groundfish species in the Prince William Sound Area. District specific abundance estimates will be generated for mature-size male Tanner crab to assess if minimum abundance thresholds to open a commercial fishery have been met. Male Tanner crab biological measurements will be collected for estimating size at morphological maturity and mature male crab will be tagged for observing seasonal movement. Biomass estimates of groundfish species, with an emphasis on Walleye pollock, Gadus chalcogrammus, will be generated for the historical trawl survey area to achieve research goals for the Exxon Valdez Oil Spill Trustees Council funded project number 22220203.

Download or read book Prince William Sound Tanner Crab Commercial Fishery Harvest Strategy Recommendations and Proposed Assessment 2022 written by Wyatt J. Rhea-Fournier and published by . This book was released on 2021 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game (ADF&G) has developed a Tanner crab Chionoecetes bairdi commercial fishery harvest strategy recommendation with an associated trawl survey assessment for the Prince William Sound Area (PWSA). Methods for developing this harvest strategy follow the approach in the Registration Area E Tanner crab harvest strategy, and methods for developing the survey assessment follow the approach for the historical ADF&G PWSA large-mesh bottom trawl survey. New areas have been proposed and defined within the PWSA with minimum abundance thresholds to open a commercial fishery and harvest rates specific to each area. A bottom trawl survey has been designed for each of the areas to estimate the abundance of Tanner crab and assess if the minimum abundance threshold has been met. Trawl surveys have been completed in 2 of the areas occurring in 2020 and 2021 with results indicating that the abundance estimate does not meet the minimum abundance threshold to open a commercial fishery for Tanner crab in those 2 areas. These recommendations will provide the basis for ADF&G proposals to be submitted at the November 2021 Alaska Board of Fisheries meeting and will inform commercial fishery management decisions in 2022.

Available in PDF, EPUB and Kindle. Book excerpt: "On April 30, 1994, Public Law 103-238 was enacted allowing significant changes to provisions within the Marine Mammal Protection Act (MMPA). Interactions between marine mammals and commercial fisheries are addressed under three new sections. This new regime replaced the interim exemption that has regulated fisheriesrelated incidental takes since 1988. Section 117, Stock Assessments, required the establishment of three regional scientific review groups to advise and report on the status of marine mammal stocks within Alaska waters, along the Pacific Coast (including Hawaii), and the Atlantic Coast (including the Gulf of Mexico). This report provides information on the marine mammal stocks of Alaska under the jurisdiction of the National Marine Fisheries Service"--Preface.

Download or read book Improving Fish Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-03-27 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.
Download or read book A Bottom Trawl Survey for Tanner Crab in Prince William Sound 2021 written by Wyatt J. Rhea-Fournier and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large-mesh bottom trawl survey of Tanner crab Chionoecetes bairdi was conducted in 2021 in the Prince William Sound Area (PWSA; Registration Area E) with the objective of establishing protocols for generating Tanner crab abundance estimates for a newly established survey area. New survey areas in PWSA were developed to assess new commercial fishery districts that were proposed at the 2021 Alaska Board of Fisheries meeting. Proposed fishery districts encompass historical fishing areas and areas fished in the recent Commissioner's permit fishery. Methodology from the historical PWSA trawl survey was applied to develop new trawl stations with the goal of calculating catch per unit effort (CPUE) to estimate abundance of historical legal-size and legal-size male Tanner crab in the surveyed area. The 2021 survey produced a CPUE for male Tanner crab that were of the historical legal size of 11.6 crab per nmi2 and was the lowest observation for any Alaska Department of Fish and Game trawl survey in the PWSA. The estimated abundance of historical legal-size male Tanner crab was 6,242 crab in the survey area, and the estimated abundance for current legal-size male Tanner crab was 40,289 crab in the survey area.
