Description
The south-west european nase is a slender cyprinid of the family Cyprinidae (Leuciscidae) reaching about 30 cm. The silvery-grey body has an inferior mouth with a straight, horny cutting edge on the lower lip, with which the fish scrapes algae and growth off stones. Endemic to the fresh water of south-western Europe (southern France and north-east Spain), in the upper and middle reaches of rivers such as the Rhône and Garonne. In schools it grazes the algal growth (aufwuchs) off the stones. In spring it migrates upstream to spawn on gravel. Nases are sensitive to water pollution and the damming of rivers, and are regarded as indicators of clean, flowing water.
