The complex of conducted studies will form and substantiate the concept of development of a new direction of aquaculture - fish farming at installations with a closed water supply system. During the assimilation of the equipment, the features of the growing sturgeon in a closed network installation were studied, the quality of the aquatic environment was characterized, the main requirements for mixed feed and rearing were determined, and much more. The results obtained should become the necessary technological basis for the introduction of a closed network installation into the general system of fish farming and agricultural production and make it possible to determine the strategy for using recirculation systems using various combined technologies, for example, the use of planting material grown in the off-season on a closed network installation, its use for further cultivation in ponds, pools. The objectivity of the accepted direction of optimization of the aquaculture system based on the installation of a closed network and the application of the chosen methodological approach is confirmed by the successful results of other works. The research work was carried out in the scientific center of the agrotechnopark at Shakarim University in Semey. As a result of the research, methods of rational breeding of fish with moderate growth and development in conditions of year-round closed water supply have been proven. Conditions were created for keeping up with the identification of factors affecting the period and quality of growth and maturation of fish. Thanks to experience, the year-round activity of sturgeons was achieved.
