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

Author

Abstract

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
O2/l, 4.5 mg O2/l and 7 mg O2/l) at the end of the 8 hour trial. Fish (initial weight and length, 30.19±2.2 g and
13.15±0.22 cm,
respectively) were distributed into 9 fiberglass rectangular tanks. The highest MDA level of all tissues was
obtained in 3.5 mg O2/l (p < 0.05). Different oxygen levels did not affect
muscle vitamin A concentration statically (p>0.05). But the highest muscle
vitamin C and E concentrations were
obtained in 7 mg O2/l. (p < 0.05), followed by 3.5 mg O2/l, while the lowest muscle vitamin C
concentration was obtained in 4.5 mg O2/l. (p < 0.05).
