Leuciscus is a genus of fish belonging to the family Cyprinidae. They are commonly called Eurasian daces; familiar species include the Common Dace and Ide. The genus is widespread form Europe to Siberia.
The European chubs were formerly included in this genus; they are now usually separated in Squalius. But delimitation of Leuciscus and Squalius is not completely resolved; some species have been moved from one genus to the other only in recent years. Petroleuciscus and Telestes have also been split off from Leuciscus in recent times; for ther latter the same holds true as for Squalius regarding the unclear delimitations.
