This book was released on 2016 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study estimated age and sex composition of Canadian-origin Yukon River Chinook salmon at the United States (U.S.)-Canada border from 1982 to 2006. In 2012, the Joint Technical Committee of the Yukon River Panel (JTC) adopted a change to the assessment methods used to estimate U.S.-Canada border passage of Canadian-origin Chinook salmon from a fish wheel mark-recapture operated by Fisheries and Oceans Canada (DFO) to a sonar with a gillnet test fishery at Eagle operated jointly by the Alaska Department of Fish and Game (ADF&G) and DFO since 2005. Because the 2 fish capturing methodologies (fish wheel versus gillnet) resulted in different age-sex compositions, it was necessary to adjust the age-sex composition assessed by the fish wheel to those of the gillnet test fishery. Age, sex, and length (ASL) data were collected from fish sampled using both methods from 2005 to 2012, except 2009. Using 2007, 2008, 2010-2012 data, fish wheel age-sex compositions were adjusted using 2 methods: (1) age-sex selectivity and (2) length selectivity, and compared to the age-sex compositions observed in the gillnet test fishery. Although both methods performed similarly, the age-sex selectivity method was slightly better than the length selectivity method to adjust age-sex composition. However, because of uncertainties about the 2007-2012 data representing historical fish wheel data, the length selectivity method was chosen to adjust the 1982-2006 age-sex composition. Length selectivity converted 1982-2006 age-sex proportion are presented, and the uncertainties and limitations are discussed.
