title: [Anomalies in the development and functioning of the reproductive system in Siberian sturgeon, Acipenser baerii Brandt (Acipenseridae), from the Yenisei River].
abstract: Based upon long-term studies, the alterations in the development and functioning of the reproductive system in the Yenisei River Siberian sturgeon are analyzed. Primary attention is paid to the malfunctions of gametogenesis during trophoplasmatic growth of the oocytes. Some anomalies were revealed for the first time in the studied population. However, these anomalies are typical for other populations of this species. These anomalies are not species-specific and may be found in other representatives of the family Acipenseridae.
