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.

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.

Download Local and Traditional Knowledge of Abundance of Chinook Salmon in the Kenai River Book in PDF, ePub and Kindle
In Alaska, statewide declines of Chinook salmon led to the development of the Chinook Salmon Research Initiative--a program aimed at better understanding these declines. Among the indicator stocks chosen for this study was the Kenai River in Southcentral Alaska. The Kenai River supports two distinct Chinook salmon runs, early and late. Together with its sockeye, coho, and pink salmon runs, the river provides opportunity for sport, personal use, educational, and commercial fisheries. This report focuses on Local Traditional Knowledge (LTK) of the Kenai River Chinook salmon stocks from long-term users of the Kenai River watershed as it pertains to patterns and trends of use in each stock.
