A Gulf of Alaska research cruise during July and August 1996 provided ocean recoveries of 698 juvenile pink Oncorhynchus gorbuscha and 350 chum O. keta salmon thermally marked during incubation at Alaskan and Canadian hatcheries. We obtained the recoveries from 2,343 pink and 1,695 chum salmon examined for thermal marks. The marked salmon migrated westerly; those released from southeastern Alaska hatcheries were caught as far west as Cape Puget and Cape Hinchinbrook, whereas pink salmon released from Prince William Sound hatcheries were found as far west as Mitrofania Island. Our results indicate that a modest research sampling program can collect sufficient numbers of thermally marked salmon for detailed studies of the growth and development of individual salmon stocks.
