Geographic Range [top]

Range Description: This species occurs in central and southern Europe with indigenous populations occurring throughout the River Danube, Dneiper and Dvina River systems (Kantor et al. 2009). It has also proved to be a successful invasive species as a consequence of commercial use (Soes et al. 2009), establishing populations in the Bodensee lake in south Germany (Soes et al. 2009), Romania (Gloër and Sîrbu 2005) and the Netherlands (Soes et al. 2009). Fauna Europaea (Bank et al. 2006) list the species for Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Germany, Hungary, Czech Republic, Romania, Slovakia (River Danube, Morava, Tisa), Ukraine, Serbia and Greece. In Russia, it is distributed through entire Dnieper River Basin and basin of the Western Dvina River in Belarus and Russia (Kantor et al. 2009).
