Abstract

Analyses were made of the phsopholipid fatty acids and the antioxidant enzymes in the carp (Cyprinus carpio morpha) at three different oxygen concentrations, corresponding to hyperoxia, hypoxia and anoxia. Variations of the oxygen concentration were found to influence the quantities of phsopholipid fatty acids, as well as the antioxidant enzyme activities. In hyperoxia and hypoxia the amount of polyunsaturated fatty acids in carp liver was higher than in anoxia, but in other tissues there was no significant differences. As to the antioxidant enzyme system, the glutathione peroxidase activity and the lipid peroxidation value increased significantly with decrease of the oxygen concentration, while the total superoxide dismutase activity decreased on lowering of the oxygen level.
