Abstract | The proximate composition, amino acid and fatty acid profiles in the fillets of wild, pond- and cage-cultured longsnout catfish (Leiocassis longirostris) were determined to identify nutritional differences. Wild fish showed higher (P < 0.05) moisture and viscerosomatic index (VSI), but lower (P < 0.05) protein, ash and gross energy than cage-cultured fish. Pond-cultured fish contained lower (P < 0.05) protein and ash contents, but higher VSI compared to cage-cuItured fish. The amino acid of glycine content was higher (P < (lOS) in wild fish than in pond- and cage-cultured fish. Most of the fatty acids had a significant difference among all fish groups. The percentages of total polyunsaturated fatty acids (E PUFAs) were higher (P < 0.05) in wild and pond-cultured fish than in cage-cultured fish. Pond-cultured fish had higher (P < 0.05) E PUFAs, eicosapentaenoic acid (EPA), docosahxaenoic acid (DHA) and E n-3/E PUFAs ratio than wild and cage-cultured fish. The differences among the wild, pond- and cage-cultured fish may be attributed to dietary components and environmental conditions of the fish. |
