Abstract
Eight species of freshwater fish from the Indus River were analyzed for their proximate composition and fatty acid (FA) profile. Differences were observed (P < 0.05) for moisture (59.95–79.45%), ash (0.05–4.95%), crude protein (17–20.09%) and lipid (0.85–18.32%) contents. The changes in FA profiles of fish species were significant (P < 0.05). The monounsaturated (MUFA) fatty acid content (24.55–48.35 g/100 g) was higher than the saturated fatty acid (SFA) (25.04–41.02 g/100 g) and polyunsaturated fatty acid (PUFA) (15.72–35.34 g/100g). The predominant PUFAs were eicosapentaenoic acid (C20:5 n-3) and docosahexaenoic acid (C22:6 n-3). All of the fish species had n-3/n-6 within the recommended values (1–4), which confirms he importance of River Indus fish as a significant dietary source of n-3 PUFA.
