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". Overfishing also seems to have contributed to the extinction. The fish was last seen in 1998 and is now listed as extinct by the IUCN. This was a short-lived species, growing to 13–16 cm long. The Turkish name "gökçe balığı"
David B. Bleak being wounded himself, Bleak rushed the Chinese troops multiple times and killed five of them—four using only his hands—before assisting the wounded, and shielding another soldier from a grenade blast. Bleak is credited with saving the patrol's wounded and ensuring that all of its members returned to allied lines. For these actions, he was awarded the Medal of Honor. In the years preceding and following his military service, Bleak worked numerous jobs around Idaho and Wyoming, working as a rancher, dairy farmer, truck driver, and meat cutter before retiring as a radioactive waste technician at the Idaho National Engineering Laboratory.
