Book Chum Salmon Stock Status and Escapement Goals in Southeast Alaska

Download or read book Chum Salmon Stock Status and Escapement Goals in Southeast Alaska written by Andrew W. Piston and published by . This book was released on 2017 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Southeast Alaska, chum salmon (Oncorhynchus keta) spawn in more than 1,200 streams. The Alaska Department of Fish and Game maintains a standardized survey program to index spawning chum salmon abundance at 87 summer-run and seven fall-run streams. Lower-bound sustainable escapement goals are established for summer-run stocks comprising aggregates of index streams over three broad subregions (Southern Southeast, Northern Southeast Inside, and Northern Southeast Outside) and sustainable escapement goal ranges are established for five fall-run stocks that support directed fisheries (Cholmondeley Sound, Port Camden, Security Bay, Excursion River, and Chilkat River). We reviewed chum salmon escapement goals and recommend that summer-run chum salmon goals continue to be based on the 25th percentiles of historical escapement index counts, primarily due to the uncertainty regarding harvest rates. We recommend reducing the Northern Southeast Inside Subregion lower-bound sustainable escapement goal from 119,000 to 107,000 fish. For fall-run chum salmon stocks, except for the Chilkat River, we also recommend continuing to base escapement goals on the 25th and 75th percentiles of historical escapement index counts, and recommend no changes at this time. Summer-run chum salmon escapement goals were met in four of the past five years in the Southern Southeast and Northern Southeast Outside subregions, and in three of the past five years in the Northern Southeast Inside Subregion. Escapement goals were met for the five fall-run stocks 84% of the time over the past 5 years. The annual common property harvest of chum salmon in Southeast Alaska averaged 6.9 million fish per year since 2007; hatchery-produced fish accounted for an average 85% of that harvest. No Southeast Alaska stocks of chum salmon currently meet the criteria for stocks of concern as defined by the State of Alaska's Policy for Management of Sustainable Salmon Fisheries (5 AAC 39.222).

Download or read book Chum Salmon Stock Status and Escapement Goals in Southeast Alaska Through 2019 written by Andrew W. Piston and published by . This book was released on 2020 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Southeast Alaska, chum salmon (Oncorhynchus keta) spawn in more than 1,200 streams. The Alaska Department of Fish and Game maintains a standardized survey program to index spawning chum salmon abundance at 87 summer-run and seven fall-run streams. Lower-bound sustainable escapement goals are established for summer-run stocks comprising aggregates of index streams over three broad subregions (Southern Southeast, Northern Southeast Inside, and Northern Southeast Outside), and sustainable escapement goal ranges are established for five fall-run stocks that support directed fisheries (Cholmondeley Sound, Port Camden, Security Bay, Excursion River, and Chilkat River). Summer-run chum salmon escapement goals were met in all of the past five years in the Southern Southeast Subregion, four of the past five years in the Northern Southeast Inside Subregion, and three of the past five years in the Northern Southeast Outside Subregion. Escapement goals were met for the five fall-run stocks 83% of the time over the past five years. No Southeast Alaska stocks of chum salmon currently meet the criteria for stocks of concern as defined by the State of Alaska’s Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222). We reviewed chum salmon escapement goals and recommend no changes at this time. The annual common property harvest of chum salmon in Southeast Alaska averaged 7.7 million fish per year since 2010; hatchery-produced fish accounted for an average 86% of that harvest. Increased straying of hatchery chum salmon into streams in the Northern Southeast Outside Subregion from a new release site at Crawfish Inlet has complicated the assessment of wild chum salmon in that subregion and additional sampling is needed to determine the variation and geographic extent of straying from the new release site.

Book Review of Salmon Escapement Goals in Southeast Alaska 2020

Download or read book Review of Salmon Escapement Goals in Southeast Alaska 2020 written by Steven C. Heinl and published by . This book was released on 2021 with total page 93 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 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 Review of Salmon Escapement Goals in Southeast Alaska 2017

Download or read book Review of Salmon Escapement Goals in Southeast Alaska 2017 written by Steven C. Heinl and published by . This book was released on 2017 with total page 97 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 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.

Book A Review of Escapement Goals for Salmon Stocks in Lower Cook Inlet Alaska 2023

Download or read book A Review of Escapement Goals for Salmon Stocks in Lower Cook Inlet Alaska 2023 written by Edward O. Otis and published by . 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.
