Genetic stock composition analysis of Chinook salmon bycatch samples from the rockfish and arrowtooth flounder 2013 Gulf of Alaska trawl fisheries and the Gulf of Alaska salmon excluder device test
A genetic analysis of samples from the Chinook salmon (Oncorhynchus t shawytscha) bycatch of the 2013 Gulf of Alaska (GOA) trawl fisheries for Pacific rockfish (Sebastes spp.) and arrowtooth (Atheresthes stomias) flounder was undertaken to determine the stock composition of the sample sets.
