Range Description

The species is widely spread in east Asia, with the Amur River being the northern border and the Lam River (Viet Nam) being the southern border of distribution range (Berg 1964, Bogutskaya and Naseka 1996, Chen et al. 1998, Kottelat 2001). It is a relatively warm water species, so it avoids mountain streams and is completely absent in the upper Amur River basin (Berg 2001). It was introduced in Uzbekistan (Kamilov and Urchinov 1995).
