Fatty acid composition of five species of freshwater fish, three marine fish and seven brackish water fish were determined by GLC. Of the saturated fatty acids C 16:0 and C 18:0 are found to be the dominant ones with C 16:0 accounting for 50‐55% of the total saturated acids. Among the monounsaturated fatty acids C 16:1 and C 18:1 and polyunsaturated fatty acids C 18:2, C 18:3, C 20:4, C 20:5 and C 22:6 are found to be the important ones. Stinging cat fish contained the highest amount of C 16:1 (16.52%). The level of arachidonic acid was fairly high in most of the fish lipids analyzed. The ratio C 18:1 /C 18:2 is higher for marine fish than for the freshwater fish and is fairly constant for each group. The fatty acid composition of brackish water fish do not show any definite pattern.
