The Lipid of cultured ayu was analyzed and compared with that of wild ayu. In the total and non-polar lipids, percentages of C
16:0, C
18:2 fatty acids in the cultured ayu were higher than those in the wild one, while percentage of C
18:3 fatty acid in the cultured ayu aws lower than that in the wild one. Odd-number fatty acids C
15:0, C
17:0 and C
19:0 were contained at high levels in the wild ayu, compared with those in the cultured one. In the phosphatidyl-choline, percentages of C
16:0 and C
22:6 fatty acids in the cultured ayu were higher than those in the wild one, while percentages of C
18:1, C
18:2 and C
20:5 fatty acids in the cultured ayu were lower than those in the wild one. In the phosphatidylethanolamine, C
16:0 and C
18:1 fatty acids were contained at high percentages in the wild ayu, compared with those in the cultured ayu. On the other hand, the percentage of C
22:6 fatty acid was high in the cultured ayu.
In addition to the fatty acid and triglyceride compositions obtained, the results of high-per-formance liquid chromatographic analysis suggest that the non-polar lipids of cultured ayu are different from those of the wild ayu in molecular species of triglycerides.
