Description

The common nase is a slender cyprinid of the family Cyprinidae reaching about 50 cm. The elongate, silvery body has a blunt, projecting snout with a transverse, sharp-edged lower mouth beneath it; with this the fish scrapes algae and diatoms from stones as if with a plane. In the breeding season the fins turn reddish and males develop white spawning tubercles. The species lives in schools in fast-flowing, oxygen-rich rivers of central Europe, such as the Danube, Rhine and Elbe, and is regarded as an indicator of clean, flowing water. In spring it migrates upstream in large schools to spawn on gravel. Through river regulation and pollution the nase has declined locally, but as a whole it is assessed as not threatened.
