Abstract
The objective of this study was to investigate the antioxidant enzyme (superoxide dismutase, SOD; glutathione, GSH; glutathione peroxidase, GPx) activities in liver and gill of rock bream, Oplegnathus fasciatus fed the experimental diets for 40 days. The experimental diets were prepared by adding with 30, 60 120 and 240 mg/kg to a commercial diet. In the liver, there were significant increases in SOD at 30~240 mg/kg. GPx activities of liver also were significantly increased at 30~120 mg/kg. The increased activities of SOD and GSH in the gills were observed in the 120 and 240 mg/kg, hence, GPx activity of gill exposed to lower concentrations of zinc (60~240 mg/kg) showed significant augmentation.
