§1

Range & habitat

The white eyed bream is native to central and eastern Europe and western Asia in rivers that drain into the Black, Azov, Caspian and Aral Seas. It has been introduced to Lake Ladoga, the northern part of the Dvina system, the Rhine and some of the rivers draining into the Baltic Sea. It has invaded the Vistula river system by Lessepsian migration through the Dnieper–Bug Canal. This species occurs in large fast flowing lowland rivers and estuaries. The eastern, brackish populations enter the lower reach of rivers for spawning.
