Description

The Beysehir nase is a cyprinid endemic to Lake Beysehir and surrounding waters in central Anatolia, Turkey. The species grows to about 15 cm and has an elongate, silvery body with an inferior, horny mouth with which it scrapes algae and aufwuchs from stones. As a bottom-feeder it lives in clear fresh water and also eats small invertebrates. Owing to its very restricted range and habitat threats the species is heavily pressured. Because of uncertainty the conservation status is left blank.
