Rudd Scardinius is a genus of ray-finned fish in the Cyprinidae family. Locally named the "Rudd" without any further qualifiers. It is also used for particular species, particularly the common rudd (S. erythrophthalmus). Its upturned mouth, allowing him to pick food items such as aquatic parasites from surface water with minimal disturbance.
The Greek Rudd 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.
