抄録

The fatty acid composition of total lipids extracted from the muscles and viscera of wild and cultured ayu (sweet smelt), caught monthly from May to November, was investigated.<br> It was noticed that the content of C15:0, C17:1, C18:3, C20:5, and C22:5 was higher in the lipids of wild ayu, and that of C18:1 and C18:2 in the cultured ayu. The composition of fatty acids differed slightly during the maturation period after summer; but the decrease of C14:0 and C16:1 and the increase of C20:5 and C22:6 in the viscera of wild ayu were remarkable.<br> The lipids of wild and cultured ayu seemed to be affected by those of sessile algae and commercial diet, respectively.
