The paper presents the results of artificial reproduction of sterlet (Acipenser ruthenus Linnaeus) carried out at the Scientific Production Center KazakhOsseter, LLP (the Mangistau region) in conditions of a recirculating aquatic system (RAS). The conditions for carrying out the main reproduction measures are described: wintering, qualifying, hormonal stimulation, obtaining reproductive products and rearing larvae. As a result, the sterlet spawning campaign was carried out in conditions of RAS in the Mangistau region, the native grown viable sterlet larvae being obtained. In the course of the work carried out in conditions of RAS in the Mangistau region there have been developed the scientific foundations and technologies for the formation and using production stocks of sturgeon, which are involved in the process of artificial reproduction. The results of the work performed could help to effectively organize the production at the commercial fish farming enterprises in the Mangistau region. The entrepreneurs of the region will have the opportunity to get acquainted with the technology of fish growing in conditions of RAS and to apply the technology for obtaining and reproducing sturgeon species in the ir local hatcheries in the future.
