Ecology of Chondrostoma nasus
 
Main Ref. Kottelat, M., 1997
Remarks Gregarious. Occurs in fairly shallow water with fast current, often beside the swirls created by piles of bridges or rocks (Ref. 30578). Found in the upper reaches of rivers. Feeds on algal growth on stones, which are scraped away with the use of its sharp, low, slit-like mouth. Migrates upstream and enters small tributaries for spawning in shallow water on gravel (Ref. 556).
