CЕЗОННІ ТА ПОРОДНІ ОСОБЛИВОСТІ ПЕРОКСИДНИХ ПРОЦЕСІВ І АКТИВНІСТЬ ЕНЗИМІВ СИСТЕМИ АНТИОКСИДАНТНОГО ЗАХИСТУ У КОРОПОВИХ РИБ
The study was conducted on three groups of fish at age of two year. Carps with different cover were hold in ponds at identical conditions. The fishes were grown on extensive technology with feeding mixtures of grains. As the material for the study the blood taken from the heart of fish after novocaine anesthesia in different seasons: spring (May), summer (August) and autumn (October) was used. The content of lipid peroxidation products (hydroperoxides lipids, TBA-active products) and enzyme activity (superoxide dismutase, catalase and glutathione peroxidase) were determined. The research has shown that the content of intermediate and final products of lipid peroxidation in plasma of scaly carp and scaleless carp in the autumn was significantly greater (PIn all research periods in the blood of scaleless and common carp, compared to the scaly carp, a significantly higher glutathione peroxidase and lower catalase activity (PThus, these data give reason to believe that the processes of lipid peroxidation and state-level of antioxidant enzymatic system in the organism of studied fish are characterized by specific features and depend on seasonal factors.
