Abstract
Improvement of methods of cultivation of sturgeon fishes is based on the analysis of data on dependence of exchange processes on abiotic factors of environment. Among big variety of abiotic factors salinity and water temperature are significant for fishes. Data on a condition of water-salt and oxidizing exchanges of the Caspian and Amur sturgeon fishes are presented. Dynamics of activity of enzymes of aerobic and anaerobic tissue respiration of cytochrome oxidase and lactate de-hydrogenase is analyzed. The revealed features of functioning of osmoregulatory system and enzymes of tissue respiration at the Amur and Caspian sturgeon fishes, first of all, are defined by conditions of their dwelling. Decreasing in efficiency of power exchange processes (lactate dehy-drogenase in a liver) at cultivation in fish-breeding conditions is fry reaction on cultivation conditions not corresponding to needs of nature of fishes.
