Polyunsaturated fatty acid accumulation and antioxidant enzyme activity in red tilapia (Oreochromis hybrid) fed high omega-3 diets

This study was conducted to investigate the change of muscle fatty acid profiles with increasing age and to measure the activities of muscle antioxidant enzymes in red tilapia (Oreochromis hybrid) fed with relatively high n-3 diet. Fish were reared in aquaria and fed with a formulated diet which was...

Fish were reared in aquaria and fed with a formulated diet which was high in n-3 polyunsaturated fatty acid (PUFA) for 75 days.

The superoxide dismutase and glutathione peroxidase activities were found to be 1.5 ± 0.1 and 0.4 ± 0.1 (U/g; Mean ± SE; n = 10), respectively. Lipid peroxidation value (MDA) was found to be 21.4 ± 0.5 nmol/g (Mean ± SE; n = 10).
