Abstract

In the examined period in the coastal area of Sevastopol fish at the age of 1 + … 2 years were dominated. Size, weight and hepatosomatic index were increasing, while the activities of peroxidase and catalase in the liver were decreasing (r = 0,80) in elder fish. Aminotransferase activity in the liver was decreased in the fish of 1 + … 2 years of age, while in the age group of 2 + … 3 years it was higher. The stabilization of the ratio of ALT / AST in the liver of fish in elder age groups plays a role to maintain a constant level of oligopeptides and prevents the development of endogenous intoxication in the organ.
