Abstract: Effects of melatonin on the levels of antioxidant enzymes including catalase (CAT), peroxidase (POD), glutathione reductase (GRd), and malondialdehyde (MDA), a lipid peroxidation marker, in erythrocytes of rainbow trout (Oncorhynchus mykiss) were investigated. The results showed that melatonin statistically activated the CAT, POD, and GRd activity (P < 0.05). Moreover, MDA levels were significantly decreased as a result of melatonin treatment (P < 0.01).
