Description

The blacknose dace is a small, stocky stream fish of the family Cyprinidae (Leuciscidae) reaching about 12 cm. The brownish body bears a dark lengthwise stripe running from the snout through the eye to the tail; in the breeding season the stripe and belly of the male turn reddish. The species is native to the fresh water of eastern North America and lives in cool, fast-flowing streams and rivers with gravel and stone bottoms. In schools it feeds on insect larvae, small crustaceans, algae and detritus. In spring and early summer it spawns on gravel. As a common stream fish it is an important prey for trout and other predators and is locally used as a bait fish.
