Book Description
Reports on estimations of the stock composition of all harvests and test fishery catches of Chinook salmon, Oncorhynchus tshawytscha, within the Yukon River drainage in 2010. Stock composition was estimated for 3 geographically-based stock groups termed Lower, Middle, and Upper, and commercial and subsistence harvest age compositions were estimated from aged scales collected. Age compositions from sampled fish, in combination with genetic stock estimates, were used to estimate the stock composition for each age class. Also includes historical data from 1981-2009.

Pages : 22
Book Description
The stock and age composition of Chinook salmon Oncorhynchus tshawytscha harvest within the Yukon River drainage was estimated for 2013. Stock composition was estimated by genetic analysis for 3 geographically-based stock groups termed Lower, Middle, and Upper. Stock composition estimates from sampled fish were applied to specific harvests across all age classes. Ages of sampled fish were determined from scales; age composition was estimated from the sample proportions in each age class. Age composition estimates were applied to specific harvests across all stock groups. The total estimated Yukon River harvest in 2013 was 13,345 Chinook salmon; of these 13.4% were estimated to be of Lower, 21.0% Middle, and 65.6% Upper stock group origin. On average over all harvests, age-1.4 fish dominated the harvest at 44.5%, age-1.3 fish were 37.2%, age-1.2 fish were 15.3%, and other age classes combined were 3.0% of the total.
