The paper considers the functional changes in the reproductive function of sturgeon species of different ages and their hybrids. The dynamics of the development of gonads of females and males during the reproductive cycle is studied. According to the results of studies, it is shown that when the hydrological and hydrochemical regimes of cultivation are stabilized, spawning intervals are reduced, as well as the time of maturity. In this case, the physiological and biochemical status of females at the final stages of maturity is normal, which is confirmed by research results. The development of oocytes in females raised under regulated conditions takes place without any deviations.
