The Antioxidant Vitamin (A, C, E) and the Lipid Peroxidation Levels in Some Tissues of Juvenile Rainbow trout (Oncorhynchus mykiss, W. 1792) at Different Oxygen Levels

In this study, the malondialdehyde (MDA) levels in the muscle, liver and kidney tissues and the antioxidant vitamin (A, C, E) levels in the muscle tissue of juvenile rainbow trout were investigated under different oxygen levels (3.5 mg O sub(2)/l, 4.5 mg O sub(2)/l and 7 mg O sub(2)/l) at the end of the 8 hour trial. Fish (initial weight and length, 30.19 plus or minus 2.2 g and 13.15 plus or minus 0.22 cm, respectively) were distributed into 9 fiberglass rectangular tanks. The highest MDA level of all tissues was obtained in 3.5 mg O sub(2)/l (p0.05). But the highest muscle vitamin C and E concentrations were obtained in 7 mg O sub(2)/l. (p
