Description

The bermejuela is a small, slender cyprinid of the family Cyprinidae (Leuciscidae) reaching about 25 cm. The silvery-grey body is inconspicuous, but in the breeding season the fin bases and belly of the male turn reddish, to which the Spanish name (bermejo = reddish-brown) refers. The species is endemic to the fresh water of the north of the Iberian Peninsula and lives in schools in slow to moderately flowing rivers, streams and lakes. As an omnivore it eats insect larvae, small crustaceans, algae and plant material. In spring it spawns in shallow, flowing water. Through water pollution, water abstraction and especially competition and predation by introduced exotics it has declined and is assessed as Near Threatened (NT).
