Description

The Prespa bleak is a slender, bright silvery schooling fish of the family Cyprinidae (Leuciscidae) reaching about 14 cm. The streamlined body has an upturned mouth with which the fish picks prey just below the surface. The species is endemic to the Prespa Lakes on the border of North Macedonia, Albania and Greece and the inflowing streams. It lives in schools in the open water and in spring moves to shallow shores and stream mouths to spawn on gravel. As an omnivore it feeds on zooplankton, surface insects and small invertebrates. The Prespa bleak has long been an important food fish for local people. Through overfishing, falling water levels and pollution it has declined and is assessed as Vulnerable (VU).
