Abstract: Long chain polyunsaturated fatty acids (LC-PUFAs) represent approximately. 20% of brain dry matter and its deficit is critical for development and its function. Eicosapentaenoic (EPA, 20:5w3) and docosahexaenoic acid (DHA, 22:6w3) are the important omega-3 PUFAs. The Arachidonic acid (AA 20:4 w-6) and DHA are of special importance in the brain and blood vessels, and are considered essential for pre and post natal brain and retinal development. The present study was, therefore conducted to know the muscles lipid fatty acid content (MTLC) and fatty acid profiles of three carp species, Cyprinus carpio (Linnaeus), Ctenopharyngodon idella (Steindachner) and Hypophthalmichthys molitrix (Richardson). The MTLC varied from 1.10±0.02% in C. idella during spring to 3.03±0.05% in C. carpio during winter season. The total PUFAs content is maximum in H. molitrix in spring and minimum in C. idella in winter. The n-3/n-6 ratio was obtained in C. idella (5.36±0.63) during spring and minimum (0.49±0.16) in C. carpio during winter.
