This book was released on 2021 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes statewide Pacific salmon escapement goals in effect in 2020 and documents escapements for all species and stocks with goals from 2012 through 2020. In addition, this report documents changes in escapement goals for both 2019 and 2020 because the report was not published in 2020 due to extenuating circumstances associated with the COVID-19 pandemic. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. Leading up to the 2018/2019 Board of Fisheries meeting cycle, escapement goals were reviewed for the Bristol Bay, Arctic-Yukon-Kuskokwim, Alaska Peninsula/Aleutian Islands, and Chignik Management Areas. As a result of these reviews, there were 29 escapement goal changes in 2019, including the elimination of 10 goals. The remaining changes were due to updates to escapement indices and/or goal development methods. There were no changes to any escapement goals in the Chignik Management Area. For the 2019/2020 Board of Fisheries meeting cycle, escapement goals were reviewed for Upper Cook Inlet, Lower Cook Inlet, and Kodiak Management Areas. As a result of these reviews, there were 32 escapement goal changes in Upper Cook Inlet that included establishing 4 new escapement goals and eliminating 12 goals. There were no escapement goal changes for Lower Cook Inlet. Because of these revisions, there were 272 salmon escapement goals in Alaska in 2019 and 264 escapement goals in 2020. In 2019, 78% of the escapement goals in Alaska were met or exceeded and 22% of the stocks did not meet minimum escapement goals. In 2020, 65% of the escapement goals were met or exceeded and 35% of the stocks did not meet minimum escapement goals.

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.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes statewide Pacific salmon escapement goals in effect in 2022 and documents escapements for all species and stocks with goals from 2014 through 2022. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. For the 2021–2022 Alaska Board of Fisheries meeting cycle, escapement goals were reviewed for the Southeast Region and Prince William Sound Management Area, which had been postponed from the 2020–2021 meeting cycle because of the COVID-19 pandemic. As a result of these reviews, there were 7 escapement goal changes for 2022. In the Southeast Region, 2 escapement goals were updated (1 coho and 1 sockeye salmon), and in Prince William Sound, 4 escapement goals were updated (2 coho and 2 sockeye salmon) and the Copper River Chinook salmon escapement goal was revised from a lower-bound SEG to an SEG with an upper and lower bound. The number of salmon escapement goals in Alaska remained at 264. In 2022, 67% of the escapement goals in Alaska were met or exceeded and 33% of the stocks did not meet minimum escapement goals.

This book was released on 1997 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A workshop was held on September 16-18, 1997 in Anchorage by the Alaska Department of Fish and Game to review Pacific salmon Oncorhynchus escapement goals for major rivers in Bristol Bay. Spawner-return data were analyzed for Kvichak, Naknek, Egegik, Ugashik, Wood, Igushik, Nushagak, and Togiak Rivers sockeye salmon 0. nerka. Sockeye smolt information was reviewed for Kvichak, Egegk, and Ugashik Rivers. Available limnological and juvenile information were analyzed fiom Lake Iliarnna. In addition, spawner-return data for Nushagak River chinook salmon O. tshawytscha were also reviewed. With a few exceptions available data supported current escapement goals in Bristol Bay. Based on this most recent escapement goal evaluation, workshop participants recommended the following changes. They recommended restructuring the escapement goal policy for Kvichak River sockeye salmon to a more robust variable escapement goal. Analyses of available data were inconclusive as to whether the underlying cause of cycles in Kvichak River sockeye production were due to inherent depensatory factors or lack of spawners. The recommended policy included an off-cycle escapement range of 2-10 million sockeye salmon with a minimum goal of 2 million and an exploitation rate of 50% on runs of 4 - 20 million. The point goal for a given off-cycle year would be 50% of the inshore Kvichak run but never less than 2 million or greater than 10 million. A 6 -10 million escapement range was proposed for pre-peak and peak cycle years with a minimum of 6 million and an exploitation rate of 50% on runs of 12 - 20 million. The point goal for a given prepeak or peak cycle year would be 50% of the inshore Kvichak run but never less than 6 million or greater than 10 million. Workshop participants also recommended managing for escapements within the middle of the current escapement goal ranges for Naknek, Egegik, and Ugashik Rivers. The current management objectives or point goals for those rivers are artifacts of past Ricker stock-recruitment models and are no longer supported by the data. Therefore, it was recommended that the management objectives be changed to 1.1 million sockeye salmon for Naknek River, 1.1 million sockeye salmon for Egegik River, and 0.85 million sockeye salmon for Ugashik River. The final recommendation coming out of the workshop was that the sockeye escapement goal range for Togiak River be changed to 100 - 200 thousand sockeye salmon. Available data supported the current management objective of 150 thousand sockeye salmon for Togiak River, but indicated an escapement range of 100 - 200 thousand would on average produce higher yields.

Download or read book Review of Salmon Escapement Goals in Bristol Bay Alaska 2021 written by Stacy L. Vega and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game interdivisional escapement goal review committee reviewed Pacific salmon Oncorhynchus spp. escapement goals for the major river systems in Bristol Bay. There were 13 escapement goals reviewed in the Bristol Bay management area for this review. The committee evaluated spawner-return data for all Bristol Bay sockeye salmon O. nerka and Chinook salmon O. tshawytscha stocks with escapement goals. For this escapement goal review, the committee recommends that all sockeye salmon escapement goals in the Bristol Bay management area remain the same. After the development of a run reconstruction model recommended at the last cycle, the committee also recommends no change to the Nushagak River Chinook salmon escapement goal for this cycle and that a run reconstruction-based escapement goal be considered during the next Board of Fisheries cycle.

This book was released on 2017 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a summary of escapement goal reviews and recommendations for major salmon stocks of the Upper Copper River and Prince William Sound Management Areas. Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Salmon Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. The escapement goal committee reviewed 29 existing escapement goals, including 1 Chinook Oncorhynchus tshawytscha , 5 chum O. keta , 2 coho O. kisutch, 16 pink O. gorbuscha (8 goals for each even- and odd-year brood line), and 5 sockeye O. nerka salmon stocks. The escapement goal committee also reviewed escapement data for Gulkana River Chinook salmon, but decided not to consider establishing an escapement goal until a sufficient time series of data are available to better understand how well the current tower count project indexes escapement. All of the existing goals were adopted in 2002, 2005, 2008, or 2011 except for the 2 coho salmon goals that were adopted in 1991. The escapement goal committee recommends all Chinook, chum, and pink salmon escapement goals be updated. The escapement goal committee recommends no modifications be made to the existing coho and sockeye salmon escapement goals, and that no goals are eliminated or created at this time.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game (ADF&G) interdivisional escapement goal review committee (committee) reviewed 41 escapement goals for Pacific salmon Oncorhynchus spp. stocks in Lower Cook Inlet (LCI). Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Salmon Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. All of the existing goals were adopted in 2017, except for 1 chum salmon O. keta stock (McNeil River, adopted 2007) and 2 sockeye salmon O. nerka stocks (Bear and English Bay Lakes, adopted 2001). Except for 2 Chinook salmon O. tshawytscha stocks (Anchor and Ninilchik Rivers) and 4 sockeye salmon stocks (English Bay, Bear, Mikfik, and Chenik Lakes), salmon escapements in LCI are primarily monitored by single or multiple aerial and/or foot surveys of appropriate stream reaches. The resulting escapement indices do not provide absolute abundance estimates suitable for estimating biological escapement goals (BEG). Consequently, all LCI goals are sustainable escapement goals (SEG). There are no escapement goals for coho salmon O. kisutch in LCI. To improve management flexibility and consistency between management areas in Alaska, the committee supported LCI transitioning from stock-specific SEGs for pink (O. gorbuscha, 18 stocks) and chum (12 stocks) salmon to aggregate escapement goals for each of the 3 LCI districts with commercial fisheries targeting these species (Southern, Outer, and Kamishak). ADF&G will continue managing LCI Chinook (3 stocks) and sockeye (8 stocks) salmon using stock-specific SEGs, with 2 Chinook (Anchor and Ninilchik Rivers) and 2 sockeye salmon (Bear and English Bay Lakes) goals changing during this review period.

Book excerpt: This report summarizes statewide Pacific salmon escapement goals in effect in 2021 and documents escapements for all species and stocks with goals from 2013 through 2021. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. Leading up to the 2020–2021 Alaska Board of Fisheries meeting cycle, escapement goals were reviewed for the Southeast Region and Prince William Sound Management Area. However, the Alaska Board of Fisheries area regulatory meetings were postponed because of the COVID-19 pandemic. Therefore, none of the recommended escapement goal changes for the Southeast Region or Prince William Sound Management Area were implemented in 2021, and the number of salmon escapement goals in Alaska remained at 264. In 2021, 70% of the escapement goals were met or exceeded and 30% of the stocks did not meet minimum escapement goals.
