Results of growing stellate sturgeon (Acipenser stellatus) obtained using cryopreserved sperm

Artificial reproduction of stellate in the Volga-Caspian fishery subregion is currently carried out by only one fish hatchery. At present, the volume of artificial reproduction has significantly decreased from 0 to 0.25 million individuals. The aim of the work was to assess the growing conditions, fish-breeding, biological and physiological characteristics of the offspring of stellate sturgeon obtained using cryopreserved sperm. It has been determined that the use of cryopreserved sexual products makes it possible to obtain viable physiologically complete offspring. The results confirm the expediency of carrying out these works in order to preserve aquatic biological resources and breeding in commercial aquaculture. The experience of growing stellate in a pond and pool has shown the effectiveness of the pool method in the first years of life.
