Abstract :Changes in the antioxidant systems of the liver tissues of sea bass insert ignore into journalissuearticles values(Dicentrarchus labrax); adapted to low salinity levels insert ignore into journalissuearticles values(0 ‰); were investigated. Malondialdehyde levels, as a specific indicator of oxidant stress, were determined. The results indicated highly significant differences among the test and control groups insert ignore into journalissuearticles values(P < 0.05);. Some histopathological destruction, liver weight and hepatosomatic index values were determined at high levels and, moreover, superoxide dismutase, glutathione peroxidase insert ignore into journalissuearticles values(GPX);, glucose-6phosphate-dehydrogenase and malondialdehyde activities increased, while reducted glutathione levels decreased in comparison with the control group. An increase in the malondialdehyde level was determined to be an indicator of lipid peroxidation.
