Squalius prespensis is a species of freshwater fish in the Cyprinidae family, growing to 25 cm (9.8 in) SL. It was originally described as a subspecies of European chub. Squalius prespensis is endemic to the Lake Prespa basin, shared between Albania, Greece, and Macedonia. It is abundant within its restricted habitat, and seems to have increased in abundance in recent years. However, it is potentially threatened by overfishing, water extraction, and pollution.
