Overview
The common nase is a European potamodromous cyprinid fish. It is often simply called the nase, but that can refer to any species of its genus Chondrostoma. Another name is sneep.
The Common nase faces severe population declines primarily due to habitat degradation and fragmentation of European river systems. Dam construction, river channelization, and water pollution have significantly reduced suitable spawning and feeding habitats, while overfishing has further pressured remaining populations.
Habitat
The nase is found naturally in drainages of the Black Sea (Danube, Dniestr, Southern Bug, Dniepr), the southern Baltic Sea (Nieman, Odra, Vistula) and the southern North Sea (to Meuse in the west). Moreover, it has been introduced to the Rhône, Loire, Hérault, and Soca/Isonzo (Italy, Slovenia) drainages. It is a migratory fish. The fish is most important food source for a Danube salmon (Huchen).
