|Reviewer(s):||Bogutskaya, N., & Smith, K. (IUCN Freshwater Biodiversity Unit)|
A widespread species with no known major widespread threats.
|Range Description:||Lower reaches and deltas of Volga, Ural, Samur, Terek (Berg, 1949; Ragimov, 1966, 1981, 1985а; Vasilieva, 1983, 2000). In Central Caspian along the western coast, and in South Caspian further eastward to Gorgan Bay (ZISP and IZA collections). We suppose that the species does not occur along the eastern coast of Central Caspian Sea; reports on its distribution there most probably refer to the later described B. mahmudbejovi.|
