Origin and distribution of chum salmon Oncorhynchus keta stocks in the western Bering Sea and North-West Pacific in 2009 and 2010
Intraspecific structure of feeding and prespawning aggregations of chum salmon in the western Bering Sea in September-October of 2009 and 2010 and in the North-West Pacific in June-July of 2009 and 2010 is investigated on the data of trawl surveys conducted by Pacific Fish.
