Beyşehir bleak Beyşehir bleak The Beyşehir bleak ("Alburnus akili"), known in Turkish as gökçe balığı, was a species of freshwater fish in the family Cyprinidae, now presumed extinct. The Beyşehir bleak was endemic to Lake Beyşehir in Central Anatolia, Turkey. It declined after the introduction of "Sander lucioperca" (zander or pikeperch) into the lake in 1955, and the introduction of "A. escherichii".
