This book was released on 2006 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual timing and abundance of adult chinook Oncorhynchus tshawytscha, sockeye O. nerka, chum O. keta, and coho O. kisutch salmon returning to the Kuskokwim River have been assessed by the Bethel drift gillnet test fishery since 1984. In 2004, the Bethel salmon test fishery operated from June 1 through August 29. The test fishery was one of the primary information sources used by managers to terminate the subsistence fishing schedule on June 20 and implement a commercial fishery for sockeye and chum salmon on June 30. In late July, the test fishery provided information allowing implementation of a commercial coho salmon fishery on July 28.

This book was released on 2016 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual abundance indices and run timing of adult Chinook Oncorhynchus tshawytscha, sockeye O. nerka, chum O. keta, and coho O. kisutch salmon returning to the Kuskokwim River have been assessed by the Bethel test fishery since 1984. In 2012, the Bethel test fishery operated from June 2 through August 26 and in 2013, from June 1 through August 24. A series of timed drifts using 5.375 inch (13.6 cm) and 8.0 inch (20.3 cm) stretch mesh gillnets were made at 3 stations across the river channel. Each series of drifts began approximately 1 hour following each high tide throughout the fishing season. Mean tidal catch per unit effort (CPUE) was calculated for each species and served as an index of abundance. The cumulative mean tidal CPUE was compared to information from earlier years to determine relative salmon abundance and run timing to help direct subsistence and commercial management decisions. The final cumulative CPUE index for 2012 was: 418 Chinook; 1,171 sockeye; 6,890 chum; and 2,440 coho salmon. The final cumulative CPUE index for 2013 was: 261 Chinook; 1,146 sockeye; 5,708 chum; and 2,865 coho salmon. The 2013 relative abundance indices were below the 2002–2012 averages for all monitored species of salmon. Run timing of Chinook salmon peaked on 26 June in 2012 and on 22 June in 2013; sockeye salmon peaked on 1 July in 2012 and on 28 June in 2013; chum salmon peaked on 7 July during 2012 and 2013; and coho salmon peaked on 11 August in 2012 and on 9 August in 2013.

Book excerpt: Annual abundance indices and run timing of adult Chinook Oncorhynchus tshawytscha, sockeye O. nerka, chum O. keta, and coho O. kisutch salmon returning to the Kuskokwim River have been assessed by the Bethel test fishery since 1984. In 2011, the Bethel test fishery operated from June 1 through August 20. A series of timed drifts using 8.0 inch and 5.375 inch stretched mesh gillnets were made at 3 stations across the river channel. Each series of drifts began approximately 1 hour following each high tide throughout the fishing season. Mean tidal catch per unit effort (CPUE) was calculated for each species and served as an index of abundance. The cumulative mean tidal CPUE was compared to information from earlier years and to the results from the lower Kuskokwim inseason subsistence salmon harvest monitoring project to determine salmon abundance and run timing to help direct subsistence and commercial management decisions. The final cumulative CPUE index through August 20 was: 201 Chinook, 1,517 sockeye, 10,028 chum, and 3,234 coho salmon. Relative abundance indices were below the 2001–2010 average for Chinook, near average for sockeye and coho salmon, and above average for chum salmon. Run timing of Chinook salmon peaked on June 23; sockeye salmon peaked on June 29; chum salmon peaked on July 7; and coho salmon peaked on August 5. Chinook salmon cumulative CPUE indices tracked historical years when escapement goals were not achieved. Sockeye, chum, and coho salmon cumulative CPUE indices tracked historical years when escapement goals were met.

Download or read book Lower Kuskokwim River Inseason Subsistence Salmon Catch Monitoring 2008 written by Holly C. Carroll and published by . This book was released on 2010 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through a collaborative effort with the Alaska Department of Fish and Game, the Orutsararmiut Native Council conducted weekly inseason surveys of Bethel Area subsistence salmon fishermen at selected fish camps and communities in the lower Kuskokwim River during the summer of 2008. The project ran for 6 weeks, from June 1 to July 15. Data collected from these surveys are used to qualitatively assess salmon run timing, relative abundance, fishermen's success in achieving their subsistence harvest goals, fishing activity and gear usage. Summaries of the surveys were relayed to fishery managers and reported at Kuskokwim River Salmon Management Working Group meetings on a weekly basis. Fishery managers and research staff use the inseason survey information as an early indication of salmon run strength and subsistence harvest trends, in conjunction with the Bethel test fishery project which provides index of relative abundance and run timing data. The inseason survey also builds management capacity by providing a forum for local users to provide input into the evaluation of salmon abundance and corresponding management strategies. Inseason subsistence catch information has also been used in combination with other information to evaluate the various management actions.

Available in PDF, EPUB and Kindle. Book excerpt: Through a collaborative effort with the Alaska Department of Fish and Game, the Orutsararmiut Native Council conducted weekly inseason surveys of Bethel Area subsistence salmon fishermen at selected fish camps and communities in the lower Kuskokwim River during the summer of 2009. The project ran from June 1 to July 12, 2009, and survey results were reported immediately to members of the Kuskokwim River Salmon Management Working Group. The objectives of this project were: to assess if the harvest goals of subsistence fishermen primarily from Bethel were being met for Chinook, chum, and sockeye salmon; to characterize run timing and relative abundance for Chinook, chum, and sockeye salmon via harvest patterns; to determine if subsistence fishermen were selectively harvesting specific salmon species using particular mesh sizes or harvest methods; and to determine if there were factors other than fish abundance affecting the relative success of subsistence fishermen in achieving their harvest goals.

Download or read book 2022 Kuskokwim River Chinook Salmon Run Reconstruction and 2023 Forecast written by Sean D. Larson and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A maximum likelihood model was used to estimate the 2022 drainagewide run size and escapement of Kuskokwim River Chinook salmon (Oncorhynchus tshawytscha). The total run was estimated to be 142,495 (95% CI: 107,579–188,743) fish, and escapement was estimated to be 107,980 (95% CI: 73,064–154,228) fish. Model estimates were informed by direct observations of the 2022 escapement at 3 weirs and 2022 harvest, combined with historical observations of escapement (up to 6 weirs and 14 aerial surveys), harvest, test fishery, and mark–recapture data dating back to 1976. Model results are adequate to draw broad conclusions about the 2022 run and escapement. The 2022 total run of Chinook salmon was below the 1976–2021 average of 211,081 fish. The drainagewide sustainable escapement goal of 65,000–120,000 was met in 2022. The 2022 Kuskokwim River Chinook salmon forecast is for a range of 115,000–170,000 fish.
