Genetic stock composition analysis of the Chinook salmon bycatch from the 2014 Bering Sea walleye pollock (Gadus chalcogrammus) trawl fishery.
A genetic analysis of samples from the Chinook salmon (Oncorhynchus tshawytscha) bycatch of the 2014 Bering Sea-Aleutian Island (BSAI) trawl fishery for walleye pollock (Gadus chalcogrammus) was undertaken to determine the overall stock composition of the bycatch. Samples were genotyped for 43 singl...
