The Danube bleak (Alburnus chalcoides) is a freshwater fish of the family Cyprinidae that grows up to 40 cm.
Description
The Danube bleak is a slender, bright-silver cyprinid of the family Cyprinidae reaching about 40 cm. The strongly compressed body has a blue-green back and an upturned mouth, a build suited to feeding just below the surface. The species occurs in the drainages of the Black Sea and the Caspian Sea and their tributaries; some populations are anadromous and run up rivers from brackish coastal water to spawn, while others stay year-round in fresh water of lakes and rivers. In schools it hunts zooplankton, insects and algae. Through dams and habitat loss the migratory populations have declined locally, though the species as a whole is assessed as not threatened.
