Dace
Dace, a name used for many different species of freshwater fish belonging to the minnow and carp family. Dace swim in schools in clear, calm waters. About 20 species are found in North America. The creek chub, or horned dace, lives in small streams in the eastern half of the United States. Other common species include the blacknose, or striped, dace and the southern redbelly dace. The full-grown dace is usually about eight inches (20 cm) long, and rarely weighs more than one pound (450 g). It is an important food for larger fish. A young dace is called a minnow.
Dace belong to the family Cyprinidae. The creek chub is Semotilus atromaculatus; blacknose dace, Rhinichthys atronasus; the southern redbelly dace, Phoxinus, or Chrosomus, erythrogaster.
