Description

The Danube bream or white-eye bream is a deep, laterally compressed bream of the family Cyprinidae reaching about 35 cm. The silvery-grey body stands out for a very long anal fin, large eyes and an inferior, protrusible mouth with which the fish sucks food from the bottom. The species lives in schools in the lower reaches of large rivers and connected lakes of the Black, Azov and Caspian Sea drainages, such as the Danube, Volga and Don. On the bottom it searches for invertebrates such as insect larvae, worms and small molluscs. In spring it migrates upstream to spawn on gravel and plants in shallow, flowing water. Locally it is landed as bycatch.
