In this study, compositions of fatty acids were investigated in fed larvae and starved larvae in shirbot (Barbus grypus). For this purpose with start feeding larvae divided to two Groups. First group feed with Commercial dry food for four week but second group starved until more than 95% of larvae died. Sampling was once a week for fed larvae and once an every two day for starved larvae. During starvation, monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) decreased but saturated fatty acids (SFA) increased significantly (p< 0.05). In fed larvae, polyunsaturated fatty acids and saturated fatty acids decreased but monounsaturated fatty acids increased significantly (p< 0.05). In both groups of larvae, palimitic acid (16:0) was predominant saturated fatty acid than increased in starved larvae. Eicosapentaenoic acid (EPA) was predominant polyunsaturated fatty acid in both groups than frist increased and then decreased.
