Description:

Genetic analysis of Chinook salmon (Oncorhynchus tshawytscha) captured as bycatch in the 2020 Bering Sea-Aleutian Island (BSAI) trawl fishery for walleye pollock (Gadus chalcogrammus) was undertaken to determine the overall stock composition of the bycatch and examine variation in stock compositions across space and time. Samples were genotyped for 37 single nucleotide polymorphism (SNP) DNA markers and stock compositions were estimated using a SNP baselined developed by the Alaska Department of Fish and Game (ADF&G).
