Sublethal effect of naphthalene on lipid peroxidation and antioxidant status in the edible marine crab Scylla serrata

The effect of naphthalene on lipid peroxidation and antioxidants status was studied in hepatopancreas, haemolymph and ovary of the Scylla serrata with reference to the active vitellogenic stage. There was an overall increase in lipid peroxidation activity in the tested samples. In contrast, the enzymatic (catalase, glutathione peroxidase, superoxide dismutase) and non-enzymatic antioxidants (vitamins C, E and glutathione) showed decreased activities for hepatopancreas, haemolymph and ovary.
