Genetic stock composition analysis of Chinook salmon bycatch from the 2013 Bering Sea Walleye pollock (Gadus chalcogrammus) trawl fishery
A genetic analysis of samples from the Chinook salmon (Oncorhynchus tshawytscha) bycatch of the 2013 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 sin...
