Book Description
Biological data were collected from Chinook (Oncorhynchus tshawytscha), summer chum (O. keta), fall chum (O. keta), and coho (O. kisutch) salmon at 19 locations along the U.S. portion of the Yukon River drainage in 2014. Age, sex, and length (ASL) data were obtained from 2,969 Chinook, 4,637 summer chum, 3,120 fall chum, and 1,654 coho salmon from commercial and subsistence harvests, as well as test fisheries and escapement projects. Samples were collected from salmon caught with gillnets, dip nets, fish wheels, beach seines, weir traps, and from hand-picked carcass. Where available, escapement estimates from weir projects were separated into temporal segments (strata) and commercial harvests were separated by fishing periods. The ASL data collected during the corresponding stratum or period was applied to the corresponding escapement estimate or commercial harvest to generate estimates of proportions and numbers by age and sex. At test fishery projects ASL data were stratified into quartiles based on catch per unit effort (CPUE), commercial period, or mesh size. In 2014, age-1.3 Chinook salmon predominated from all of the test fishery and escapement projects; and most of the subsistence harvest samples. At many long standing projects 5-year-old (age-1.3 and age-2.2) Chinook salmon percentages were above the long-term and 5-year averages, whereas the 4-year-old (age-1.2 and age-2.1) and 6-year-old (age-1.4 and age-2.3) percentages were near or below the long-term and 5-year averages. Both summer and fall chum salmon samples were primarily composed of age-0.3 and age-0.4 fish. Age-2.1 coho salmon predominated in the commercial and test fishery samples.
