Abstract: The objective of the present study was to investigate the importance of the antioxidant enzymes; glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase (GR), superoxide dismutase (SOD), glutathione peroxidase (GP) and catalase (CAT) in defense against toxic reactive oxygen species (ROS). For this purpose, comparative studies were performed on the antioxidant enzyme activities in red cells of rainbow trout (Oncorhynchus mykiss) between flow-through and recirculated breeding systems G6PD, GR and SOD activities were found significantly lower in reuse system than flow-through system. But, GP and CAT activities were increased significantly in the erythrocyte of rainbow trout held in reuse water tanks.
