Description

The asprete is a spindle-shaped, perch-like bottom fish of the family Percidae reaching about 11 cm. The almost cylindrical, brown-mottled body with two separate dorsal fins is strongly adapted to life among stones on the bottom of fast-flowing mountain rivers. The species is a living fossil: it is the only member of its genus and is regarded as one of the oldest and rarest fish in Europe. It is endemic to a few rivers in Romania but, through dams, deforestation and pollution, has become almost confined to a short stretch of the river Vâlsan. At night it hunts insect larvae and small invertebrates among the stones. With an extremely small population it is assessed as Critically Endangered (CR) and is the subject of intensive conservation.
