Abstract

Proximate, amino and fatty acids has been compared between Penaeus monodon (Fabricius, 1798), Fenneropenaeus indicus (H. Milne Edwards, 1837) and Aristeus virilis (Bate, 1881) collected from the Nagapattinam landing centre (south east coast of India). The shrimps showed a significant (p<0.05) result and varying concentration of protein, lipid, carbohydrate and moisture. Higher concentration of the major component, protein was found in A. virilis (17.25) followed by F. indicus and P. monodon. The amino acid composition and their ratios evinced shrimp as a nutritional diet in the  resent study. The essential amino acids that cannot be synthesized in human body are prevailing more in A. virilis than the other two shrimps.   The fatty acids including saturated fatty acids (SFAs), Mono unsaturated fatty acids (MUFAs) and Poly unsaturated fatty acids (PUFAs) were analyzed. The shrimps have higher concentrations of Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) and their ratios were estimated. A.virilis (47.1% and 23.6% of EPA and DHA was more concentrated with the UFAs respectively than the other two shrimps. A. virlis had 47% of EPA and 3.6% DHA than other two shrimps.
