Resumo: | The paper deals with peculiarities of lipid metabolism in the liver and muscles of the Black sea fishes: bottom inactive Scorpaena porcus L. and pelagic quickly swimming Spicara smaris L. in the prespawning and prewinter periods of the year cycle. The character of metabolic processes was judged from radiocarbon (14C) accumulation and excretion by the fish tissue lipids after a single intraperitoneal injection of I-14C-acetate. Seasonal differences in the character of lipid metabolism are found only in those tissue where accumulation of reserve lipids does not occur (Scorpaens porcus L. muscles and Spicara smaris L. liver). In the prespawning period the level of lipid metabolism in the muscles of Scorpaens porcus L. was considerably higher, and that in the Spicara smaris L. liver was on the contrary lower than in the period before wintering. The seasonal differences are due to the functional peculiarities of the fishes during the period under study. In the Scorpaena porcus L. liver and Spicara smaris L. muscles, the main lipid depots of these fishes, seasonal differences in lipid metabolism are insufficiently pronounced. This is connected with the fact that lipid metabolism in the examined tissues was stabilized during the periods under study: in the prespawning period lipid reserves have not been used yet, and in the prewintering period accumulation of the reserves has been completed.
