Book Pink Salmon Stock Status and Escapement Goals in Southeast Alaska Through 2019

Download or read book Pink 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 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1990s and 2000s, pink salmon were harvested in Southeast Alaska at the highest levels since record keeping began in the late 19th century. Since 2006, the average annual harvest has dropped, largely due to poor even-year returns to the Northern Southeast Inside Subregion of Southeast Alaska, but also due to recent declines in odd-year returns. Even-year pink salmon harvests averaged only 20 million fish per year since 2006, primarily due to very low harvests in the Northern Southeast Inside Subregion, which averaged only 2.3 million fish per year during that time. Odd-year harvests to the Northern Southeast Inside Subregion remained strong through 2017, but dropped to approximately 2 million in 2019, which was the lowest odd-year harvest since the late 1970s. Even-year harvests in the Southern Southeast Subregion quickly rebounded after a very low harvest of 3.3 million fish in 2006. The harvest of 33.2 million fish in the Southern Southeast Subregion in 2014 was the largest even-year harvest since 1996 and was approximately double the 1960–2012 average harvest for even years. From 2014 to 2019, the average harvest of 12.3 million in the Southern Southeast Subregion was far below the average harvest of 27.7 million from 1985 to 2014. Pink salmon escapement indices have been consistently within or above escapement goals in the Southern Southeast and Northern Southeast Outside subregions but were below the escapement goal in the Northern Southeast Inside Subregion in four of the past five even years and in three of the past five years overall. We reviewed pink salmon escapement goals and recommend no changes. At this time, no stocks of pink salmon in Southeast Alaska 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).

Book Chum Salmon Stock Status and Escapement Goals in Southeast Alaska Through 2019

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.

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).

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.
