Abstract
The work presents the biological characteristics of the females of the Amur sturgeon caught in the Amur River: indicators of the length and body weight of females, the mass and stages of maturity of their gonads, the dimensional mass characteristic of oocytes, indicators of individual absolute and relative fertility. The results of histological examination of gonads are presented. Degenerative changes in the structure of the reproductive system were noted, reducing the effectiveness of natural reproduction.
