"IUCN3.1" . . . "The Bey\u015Fehir bleak (Alburnus akili), known in Turkish as g\u00F6k\u00E7e bal\u0131\u011F\u0131, was a species of freshwater fish in the Cyprinidae family, now presumed extinct.The Bey\u015Fehir bleak was endemic to Lake Bey\u015Fehir 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. Overfishing also seems to have contributed to the extinction."@en . . . "Bey\u015Fehir bleak"@en . . . . . . "EX" .
