Aim. Tthe article presents the results of breeding broodstock of sturgeon in the Shirokolski fish farm. The volume of commodity output reached 50 tonnes of sturgeon, and two tones black caviar. After drilling termal well volume growth may reach 100 t, obtaining food caviar 5 t.Location. Russian Federation, Dagestan Republic.Methods. We used the standard ichthyological research methodology. Results. At the present time the plant formed one of the largest sturgeon broodstock total biomass of more than 50 t, which include clean lines: Beluga, Russian and Siberian sturgeon, sterlet, paddlefish, and hybrid forms. The plant research for the early detection of sex by ultrasound scan. The main role of bester, which is used to obtain the food caviar. The biomass of the herd is about 30 tonnes per year is about 10 tons of breeders. Mature females Bester in our conditions in 7-8 years. Sterlet is used as producers for the purpose of reproduction and food caviar. Maintenance of broodstock is 6000 fishes and approximately 2000 breeders of medium weight from 1.5 to 6.0 kg. Mature female starlet at age 4- 5 years.Main conclusions. The results convince us that the development of sturgeon aquaculture is one of the feasible ways not only to increase employment and reduce social poaching, but also stabilizing the feedstock, substantial improvements in the efficiency of hatcheries and processors.
