Abstract
The article presents the results of research work on the creation of a replenishment-breeding herd of Siberian sturgeon. The research work was carried out in the conditions of closed system water supply (emergency situations) at" educational and scientificcomplex of experimental industrial production of aquaculture " LLP. The hydrochemical state of the water of the emergency situations basins was analyzed. The conditions of keeping in the breeding herd (Tau) were studied, the technological equipment of theTSS was evaluated and a morphological analysis of individuals was carried out, as well as the article analyzed the biological indicators of fish breeding of individuals and spring Fry of Siberian sturgeon, age and quantitative composition of Siberian sturgeon. As a result, the results of the morphometric study show that the tendency to increase the coefficient of belching in adult individuals of Siberian sturgeon, as well as the parameters of relative body capture of Siberian sturgeon, is 5.3% higher than in age groups. In the conditions of fish farms, the conditions for the formation of the Tau of Siberian sturgeon met regulatory requirements, and the growth observed during the year also met the standard. An important issue in breeding in commercial farms and reproduction centers is the Prevention of inbreeding. When breeding Sturgeon, as a rule, a small number of broodbugs or only a few pairs are used, which often leads to inbreeding and loss of natural polymorphism. In order to avoid it, it is necessary to use at least 20 seed pairs when planting a female herd and further in the process of its reproduction. For this purpose, the structure of TAS should provide the possibility of industrial reflectivity
