The hydrocarbon components in some tissues of sockeye salmon Oncorhynchus nerka and chum salmon Oncorhynchus keta caught in the Gulf of Alaska were investigated with open-tubular gas-liquid chromatography. At least 60 peaks were detected, of which 26 components were identified. The salmons had normal hydrocarbons ranging in chain length from C13 to C28 with an odd-chain predominance. The major hydrocarbons of the present samples were pristane and squalene. The total contents of these components in all samples exceeded 60% of the total hydrocarbons. In particular, pristane accounted for 85-90% of total hydrocarbons in the viscera and stomach contents of both salmons. Norphytene, phytane, and phytadiene were also detected in these samples. The results in this study suggested that the salmons analyzed in the Gulf of Alaska were hardly polluted by crude oil.
