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 Southeast Alaska in 2017. As of 2016, escapement goals were established for 12 Chinook, 14 sockeye, 14 coho, 4 pink, and 8 chum salmon stocks. The Southeast escapement goal review committee recommended changes to escapement goals to the directors of the divisions of Commercial Fisheries and Sport Fish as follows: (1, 2, 3) replace escapement goal ranges for Chickamin, Blossom, and Keta river Chinook salmon, which are expressed in index survey counts, with ranges expressed as total escapement; (4) eliminate the Klukshu (Alsek) River Chinook salmon goal; (5) eliminate the combined East Alsek-Doame river sockeye salmon biological escapement goal (13,000-26,000 fish) and replace it with a sustainable escapement goal (range 9,000-24,000 fish) germane only to the East Alsek River; (6) eliminate the Lost River sockeye salmon goal; (7) eliminate the Alsek River sockeye salmon goal (8); change the Berners River coho salmon biological escapement goal from 4,000-9,200 fish to 3,600-8,100 fish; (9) change the Tsiu-Tsivat river coho salmon goal from a biological escapement goal to a sustainable escapement goal while maintaining the same goal of 10,000-29,000 fish; (10) eliminate the Ford Arm Creek coho salmon goal; (11) eliminate the Situk River pink salmon goal; and (12) change the aggregate Northern Southeast Inside summer-run chum salmon lower bound sustainable escapement goal from 119,000 to 107,000 fish. As a result of these recommendations, a total of 47 Southeast Alaska escapement goals would be established for 11 Chinook, 12 sockeye, 13 coho, 3 pink, and 8 chum salmon stocks.

Download or read book A Review of Escapement Goals for Salmon Stocks in Lower Cook Inlet Alaska 2016 written by Edward O. Otis and published by . This book was released on 2016 with total page 77 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 Pacific salmon Oncorhynchus spp. escapement goals for major river systems in Lower Cook Inlet (LCI). There were 41 escapement goals evaluated in LCI during this review. Except for 2 Chinook salmon Oncorhynchus tshawytscha stocks (Anchor and Ninilchik rivers) and 4 sockeye salmon O. nerka, 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, ADF&G developed sustainable escapement goals (SEG) for 3 Chinook, 12 chum O. keta, 18 pink O. gorbuscha, and 8 sockeye salmon stocks monitored in LCI. There are no escapement goals for coho salmon O. kisutch in LCI. Escapement performance for Chinook, chum, pink, and sockeye salmon relative to the existing goals has been good during the past 4 years, with a harvestable surplus available in 33--100% of streams during most years. Because most of the current goals were implemented 15 years ago and new methods were recently developed for establishing SEGs, the committee recommended changing 37 of 41 escapement goals for salmon stocks in LCI to incorporate the additional escapement data and new methods.

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 Southeast Alaska in August of 2019 and again early in 2020. Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. There is a total of 47 escapement goals in Southeast Alaska for 11 Chinook, 12 sockeye, 13 coho, 3 pink, and 8 chum salmon stocks. The Southeast escapement goal review committee recommended changes to these goals to the directors of the Divisions of Commercial Fisheries and Sport Fish as follows: (1) change the Taku River sockeye salmon sustainable escapement goal range of 71,000–80,000 fish (based on a historical dataset) to a biological escapement goal range of 40,000–75,000 fish based on a revised dataset; and (2) change the Situk River coho salmon biological escapement goal range of 3,300–9,800 fish to a sustainable escapement goal range of 3,800–9,600 fish based on percentiles of historical survey counts. Detailed analyses of Chilkoot, Speel, and Redoubt Lakes sockeye salmon escapement goals are also documented here, although the committee did not recommend changes to those goals.

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.
Download or read book Klukshu River Sockeye Salmon Stock Status and Action Plan 2021 written by Richard A. Hoffman (Biologist) and published by . This book was released on 2022 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to guidelines established in the Policy for the management of sustainable salmon fisheries (SSFP), the Alaska Department of Fish and Game (department) recommended that the Klukshu River sockeye salmon (Oncorhynchus nerka) be designated as a “stock of management concern” in October 2020. A management concern is defined as “a concern arising from a chronic inability, despite use of specific management measures, to maintain escapements for a salmon stock within the bounds of the SEG [sustainable escapement goal], BEG [biological escapement goal], OEG [optimum escapement goal], or other specified management objectives for the fishery.” Klukshu River sockeye salmon escapements have been below the lower bound of the current BEG range in 4 of the last 5 years, 2016–2020. Klukshu River is a tributary of the Alsek River and is entirely within Yukon, Canada. Klukshu River sockeye salmon are harvested primarily in a commercial set gillnet fishery that operates in the lower portions of the Alsek River and in Dry Bay in the U.S. and in a Champagne–Aishihik First Nation Aboriginal fishery that takes place in or near the Klukshu River in Canada. Alsek River salmon fisheries are managed under the provisions of the Pacific Salmon Treaty (PST) and management actions since 2018 have been designed to reduce harvest of Klukshu River sockeye salmon.

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 Southeast Alaska in 2014. As specified in the Pacific Salmon Treaty, escapement goal recommendations for transboundary Alsek and Klukshu river Chinook and sockeye salmon runs underwent bilateral U.S./Canada review, and recommended changes were adopted by the Transboundary River Panel of the Pacific Salmon Commission in 2013. Thus, as of 2013, escapement goals were established for 12 Chinook, 14 sockeye, 14 coho, 4 pink, and 8 chum salmon stocks. The Southeast escapement goal review committee recommended to the directors of the divisions of Commercial Fisheries and Sport Fish that all but 5 of those escapement goals remain unchanged. The committee recommended (1) changing the Speel Lake sockeye salmon goal from a biological escapement goal range of 4,00-13,000 fish to a sustainable escapement goal range of 4,000-9,000 fish; (2) changing the Lost River coho salmon goal from a lower-bound sustainable escapement goal of 2,200 fish to a sustainable escapement goal range of 1,400-4,200 fish, and changing the name of the goal to Tawah Creek (Lost River); (3-4) increasing aggregate lower-bound sustainable escapement goals for summer-run chum salmon in the Southern Southeast and Northern Southeast Outside subregions to account for the addition of new index streams to those stock groups; and, finally, (5) changing the Chilkat River fall-run chum salmon sustainable escapement goal range of 75,000-170,000 fish to a range of 75,000-250,000 fish.

Available in PDF, EPUB and Kindle. Book excerpt: In October 2020, an interdivisional team of staff from the Alaska Department of Fish and Game reviewed existing Pacific salmon Oncorhynchus escapement goals in the Chignik Management Area (CMA). The 6 CMA salmon escapement goals were last reviewed in 2018. Starting in 2020, the team reviewed recent data to determine whether substantial new information existed to warrant analyzing and updating the goals. The team determined Chignik sockeye salmon warranted further review. The team revised the early- and late-run sockeye salmon goals to a single biological escapement goal (BEG) of 450,000 to 800,000 fish to address overlaps and subsequent bottlenecks in freshwater rearing between the 2 major stocks. The early- and late-run sockeye salmon goals will be eliminated, and no new goals were added for systems currently without escapement goals.

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.
Download or read book Escapement Goal Recommendations for Select Arctic Yukon Kuskokwim Region Salmon Stocks 2007 written by Linda K. Brannian and published by . This book was released on 2006 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Alaska Department of Fish and Game Escapement Goal Review Team (review team) was convened to review salmon escapement goals for the Arctic-Yukon-Kuskokwim Region in preparation for the January 2007 meeting of the Alaska Board of Fisheries. The review team made recommendations to the Regional Supervisors of the Divisions of Commercial Fisheries and Sport Fish, who in turn make recommendations to the directors of the two divisions. The review team recommended establishing three new escapement goals in the Kuskokwim Management Area, no new goals in the Yukon Management Area, and two new goals in the Norton Sound-Port Clarence and Kotzebue Management Areas. In addition they recommended revising three escapement goals in the Kuskokwim Management Area (one for Chinook salmon, one for chum salmon, and one for sockeye salmon), none in the Yukon Management Area, and five chum salmon goals in the Kotzebue Management Area. They also recommended discontinuing one aerial survey escapement goal in the Kuskokwim Management Area where that goal was recommended to be replaced with a weir goal. While most of the recommended new goals are sustainable escapement goals, spawner-recruit analyses were performed to recommend biological escapement goals for Kobuk and Noatak rivers chum salmon in the Kotzebue Management Area and Middle Fork Goodnews River Chinook and Sockeye salmon in the Kuskokwim Management Area. The escapement goal review team also made recommendations for specific stocks to be reviewed in detail prior to the 2010 Alaska Board of Fisheries meeting.
