Scardinius is a genus of ray-finned fish in the family Cyprinidae commonly called rudds. Locally, the name "rudd" without any further qualifiers is also used for individual species, particularly the common rudd (S. erythrophthalmus). The rudd can be distinguished from the very similar roach by way of the rudd's upturned mouth, allowing it to pick food items such as aquatic insects from the surface of the water with minimal disturbance.

The Greek rudd (S. graecus) is a similar fish, about 40 cm long. It occurs only in the southern tip of the Greek mainland. It lives in lakes and slow-flowing rivers, forming large schools. It spawns around April–June among underwater plants in shallow water. It feeds on small crustaceans, the larvae and pupae of insects, and on plant material. The majority of its food is taken at or near the surface of the water. The fish is not usually found in deep water. Very little is known about the biology of this species. It is important locally, both to anglers and commercial companies.^[1]

What is a stub?

A stub is an article containing only a few sentences of text which is too short to provide encyclopedic coverage of a subject.

How is a stub identified?

If possible, try to find the most appropriate stub template for the article. A full list can be found at Wikipedia:WikiProject Stub sorting/List of stubs.
More than one stub template may be used, if necessary, though no more than four should be used on any article.
