Results of artificial reproduction of the starry sturgeon in the Azov–Don Region in 2021–2022
Over the course of the monitoring surveys conducted in 2021–2022, the specific features of the starry sturgeon reproduction have been investigated, which covered the span from the adaptation of breeders to the release of juveniles into a natural water body. The results of this study indicate that the starry sturgeon females from the broodstock have low reproduction capacity, as well as decreased embryo survival rates and larvae yield. The starry sturgeon juveniles reared in tanks were characterized by low growth rates, decreased feed conversion efficiency, and acceptable physiological status. It has been shown that rearing the starry sturgeon juveniles in tanks is less expedient than using a combined method.
