Abstract: Changes in fatty acid composition were investigated during the early development stages (eggs, 12h after fertilization, yolk sac larvae, yolk-sac absorption larvae and larvae feed on egg suspension) of Silver carp (Hypophetalmyctis molitrix). Oleic 18:1(n-9) acid was the preferentially monounsaturated fatty acids and such as monounsaturated fatty acid catabolized as energy during embryonic and larval development. During development, the increase in levels of polyunsaturated fatty acids (PUFA), eicosapentaenoic (20:5n-3, EPA) and docosahexaenoic (22:6n-3, DHA) acid was observed that stated their structural components. Our results can give information about the requirements during early and late ontogeny of silver carp larvae at the start of endogenous and exogenous Feeding.
