Alien Vimba Bream Vimba vimba (Cyprinidae) in the Ural River Basin

This paper provides data on the occurrence of vimba bream (Vimba vimba) in the middle reaches of the Ural River. One of the distinguishing features of this species from the native Caspian vimba (V. persa) is a greater number of scales in the lateral line. In the late 1980s, vimba bream was introduced from the Don River basin into the Volga River basin. Having successfully adapted in the Volgograd Reservoir, the species subsequently colonized the unregulated area of the Lower Volga and the northern and, apparently, middle parts of the Caspian Sea and formed a stable residential population in the Ural River basin.
