Challenges in artificial reproduction of the sterlet sturgeon in the Azov–Don Region at the present time
The abundance of the sterlet population in the Don River is maintained by means of annual releases of its juveniles. For the reproduction, the breeders from the broodstock created in the Don Sturgeon Hatchery are used. Over 2019–2022, sturgeon hatcheries of the Azov-Don Branch of the FSBI “Glavrybvod” (Main Basin Department for Fisheries and Conservation of Aquatic Biological Resources) at the Don River downstream from Tsimlyansk Reservoir released 6.893 million sterlet juveniles exceeding 1.5 g in weight. Analysis of the data has shown that the efficiency of reproduction in this sturgeon species depends on the quality of the reared juveniles and the breeders involved in reproduction.
