[Tissue specificity of antioxidant system functioning and lipid peroxidation in different age groups of Amur carp]

Key features of tissue enzymes functioning in antioxidant system (AOS) in sexually mature and immature individuals of Amur carp were studied. The activity of antioxidant enzymes was highest in the myocardium and subjected to age-related changes. It was concluded that changes in the functioning of AOS and intensity of lipid peroxidation processes are characterized by organ-tissue metabolic features and age peculiarities of metabolism that is most expressed in the myocardium.
