Luciobarbus esocinus Heckel, 1843

Distribution in the area. Endemic. Widespread in the Euphrates and Tigris drainages. It was also known from the Qweik River, where it is now extirpated.

Remarks. Luciobarbus esocinus is one of the largest Cyprinids in the world and a small-scale angling tourism has developed around this species in the last years, especially in Turkey and Iran. It is also a major commercial species and seems to be overfished in large if not all parts of its range. However, data on population trends are very rare and based on fisheries statistics.
