The chemical and amino acid compositions in several tissues of cultured and wild coho salmon Oncorhychus kisutch were measured and compared. A remarkable difference in lipid content in the ordinary muscle and integument was found between the cultured and wild fish. The former fish contained lipids about 4 times higher than the latter fish. The chemical composition of the dark muscle of these fish, however, resembled each other. The major amino acids of the flesh were Asp, Glu, Leu and Lys. There was no marked difference in the amino acid composition between the cultured and wild fish. Extractive-nitrogen and free amino acid contents were higher in the liver and viscera than those in the other tissues. The major free amino acids in these tissues were Ala and Glu. The other free amino acids, abundantly found were His, Gin and Arg in the ordinary muscle, liver and testis respectively. The dark muscle, liver, viscera and gonad contained high levels of taurine, while the ordinary muscle had large amounts of anserine.
