Available in PDF, EPUB and Kindle. Book excerpt: Adaptive resolution imaging sonar (ARIS) was used for the first time in 2018 to estimate the abundance of late-run Chinook salmon (Oncorhynchus tshawytscha) at river mile (RM) 8 of the Kasilof River. The same methods were used to estimate late-run Chinook salmon abundance in 2019 and 2020. In 2019, the sonar was operated from 15 June through 31 August. In 2020, the sonar was operated from 15 June through 22 August. Net upstream passage of late-run Chinook salmon greater than or equal to 75 cm mid eye to tail fork length (METF) as measured by ARIS was estimated to be 4,507 (SE = 184) in 2019 and 3,388 (SE = 165) in 2020. The 2019 cumulative late-run Chinook salmon abundance estimate of fish greater than or equal to 75 cm METF was higher than the 2018 and 2020 estimates. Run timing in 2019 and 2020 was earlier than in 2018.

Available in PDF, EPUB and Kindle. Book excerpt: Although a sport fishery for late-run Kasilof River Chinook salmon (Oncorhynchus tshawytscha) is prosecuted downstream of river kilometer (RKM) 13 and a commercial fishery occurs in nearby marine waters, the inriver abundance of late-run Kasilof River Chinook salmon has been unknown for most years. The goal of this study was to estimate the daily net upstream passage of salmon 75 cm or longer from mid eye to tail fork (METF) past RKM 13 of the Kasilof River from 15 June through 31 August 2018 using adaptive resolution imaging sonar (ARIS). Net upstream passage of Chinook salmon greater than or equal to 75 cm METF as measured by ARIS was estimated to be 3,458 (SE 166). Chinook salmon passage estimates were lower than those from a prior mark–recapture study, but run timing was similar.

This book was released on 2017 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stock-specific abundance and run timing model (SSART) was fit to relative and absolute estimates of abundance, genetic stock identification data, radiotelemetry data, and estimates of harvest for Kenai River Chinook salmon (Oncorhynchus tshawytscha) from 2007 to 2014. The methods follow a model of the 2007-2012 data except that inference is restricted to Chinook salmon 75 cm mid eye to tail fork (METF) or longer for all results in this report. Bayesian statistical methods were employed to estimate inriver abundance and run timing by stock at river mile 8.6 of the Kenai River. Abundance of early-run Chinook salmon ranged from 1,940 (SE 307) in 2013 to 8,637 (SE 2,215) in 2007. Abundance of late-run Chinook salmon ranged from 9,949 (SE 2,138) in 2010 to 37,180 (SE 10,340) in 2007. Fish from Killey River-Benjamin Creek, Funny River-Slikok Creek, and Quartz-Crescent creeks migrated upstream primarily prior to 30 June; fish from Grant Creek and Russian River migrated upstream primarily between 16 June and 31 July; and fish from Mainstem Kenai River-Juneau Creek migrated upstream primarily after 16 June. Tributary stocks had greater relative abundance within the run before 16 June and the Mainstem-Juneau Creek stock had greater relative abundance after 30 June. Between 16 June and 30 June, tributary stocks had greater relative abundance in 6 of 8 years while Mainstem-Juneau Creek fish had greater relative abundance in the other 2 years.

This book was released on 2016 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stock-specific abundance and run timing model (SSART) was fit to relative and absolute estimates of abundance, genetic stock identification data, radiotelemetry data, and creel survey estimates of harvest for Kenai River Chinook salmon (Oncorhynchus tshawytscha) from 2007 to 2012. Bayesian statistical methods were employed to estimate inriver abundance and run timing by stock at river mile 8.6 of the Kenai River. Abundance of early-run Chinook salmon ranged from 6,739 (SE 819) in 2012 to 12,300 (SE 2,087) in 2007. Abundance of late-run Chinook salmon ranged from 22,190 (SE 3,815) in 2010 to 48,370 (SE 8,641) in 2007. Tributary stocks had greater relative abundance within the run before 15 June and the Mainstem-Juneau Creek stock had greater relative abundance after 15 June. Fish from Killey River–Benjamin Creek, Funny River-Slikok Creek, and Quartz-Crescent creeks migrated upstream primarilyduring the first 3 of 6 time strata; fish from Grant Creek and Russian River migrated upstream primarily during the third through fifth time strata; and fish from Mainstem Kenai River-Juneau Creek migrated upstream primarily during the last 3 time strata.

This book was released on 2017 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Age-structured state-space spawner-recruit models were fit to 1986-2015 data on abundance, harvest, and age composition for early and late runs of Kenai River Chinook salmon (Oncorhynchus tshawytscha), 75 cm mid eye to tail fork (METF) and longer. Historical annual run abundance, stock recruitment parameters, and fishery management reference points were estimated from these models. Sustainable Escapement Goals of 2,800-5,600 (early run) and 13,500-27,000 (late run) Chinook salmon 75 cm METF and longer are recommended, and their attributes and limitations discussed. Fish 75 cm METF (approximately 33.3 in total length) and longer can be assessed directly by imaging sonar in the Kenai River at river mile 13.7.
