Lipid and fatty acid compositions of cultured and wild coho salmon were compared. Tri-glyceride (TG) was the main component of lipids in all the tissues investigated. TG contents of ordinary and dark muscles (ca. 90%) were higher than those of liver, gonad and viscera (50-70%). The main fatty acids of cultured fish were C16:0, C18:1, C20.3 and C22:6, while those of wild fish were C16:0, C18:1, C20:1, C22:1 and C22:6. The fatty acids such as C20:1 and C22:1 were higher in wild fish than in cultured fish. Monoenoic fatty acids were the main components of fatty acids in ordinary muscle, dark muscle, viscera, integument, head and bone, and testis. Polyenoic fatty acids were higher in liver and ovary than in the other tissues.
