A dace is a small fish that can be one of many different species. The unmodified name is usually a reference to the common dace. This, like most fishes called "daces", belongs to the family Cyprinidae, mostly in subfamily Leuciscinae.
Phoxinus is a genus of freshwater fish in the family Leuciscidae of order Cypriniformes, and the only members of the subfamily Phoxininae, or Eurasian minnows. The type species is Phoxinus phoxinus. The other species in this genus are also commonly known as minnows. The name "minnow" was what early English fisherman used to describe "small and insignificant". The genus Phoxinus is found throughout Eurasia, and includes 21 known species. Previously, members of the North American genus Chrosomus were also believed to form part of this genus.
Rhinichthys, known as the riffle daces, is a genus of freshwater fish in the carp family (Cyprinidae) of the order Cypriniformes. The type species is Rhinichthys atratulus, the blacknose dace. Rhinichthys species range throughout North America.
The northern redbelly dace is a freshwater cyprinid fish, generally found in lakes and small streams in the northeastern United States and eastern Canada. Ranging from 1-30 inches, it is one of forty-four species from the minnow and Carp family of Cyprinidae in these areas.
Notropis is a genus of freshwater fish in the family Cyprinidae. They are known commonly as eastern shiners. They are native to North America, and are the continent's second largest genus.
The southern redbelly dace, is a North American species of temperate freshwater fish of the family Cyprinidae. The natural geographic range extends from Western New York to Minnesota, and south to Oklahoma, Arkansas, and Alabama. This fish prefers flowing pools of creeks and streams.
Cyprinella is a genus of fish in the family Cyprinidae, the carps and minnows. They are known as the satinfin shiners. They are native to North America, and some are among the most common freshwater fish species on the eastern side of the continent. Conversely, several Cyprinella species with small distributions are threatened and the Maravillas Creek subspecies of the red shiner is extinct.
The blackside dace ) is a species of ray-finned fish in the family Cyprinidae. It is endemic to the Cumberland River drainage in Kentucky and Tennessee as well as the Powell River drainage in Virginia in the United States. It is a federally listed threatened species.
The Tennessee dace is a species of ray-finned fish in the family Cyprinidae. It is found only in the United States; particularly in northeast Tennessee and southwest Virginia, and parts of extreme northwest Georgia. Until recently, they were considered a subspecies of mountain redbelly dace. They are commonly found in East Tennessee in spring fed first-order streams, often in silt and fine gravel pools, or undercut banks. These streams usually do not exceed two meters in width.
The rainbow shiner is a North American species of ray-finned fish in the genus Notropis.
Eastern blacknose dace is a species of ray-finned fish in the genus Rhinichthys. Its name originates from the Old French word "dars" which is the nominative form of the word "dart" in reference to their swimming pattern. The western blacknose dace formerly was considered conspecific. While morphologically the two species are not significantly different, they are allopatric. The eastern blacknose dace is found across the southeast portion of Canada and down along the United States' east coast. It is dark brown to olive on its dorsal surface and silvery white below, the two shades separated by the darkly pigmented lateral line. In the breeding season, males develop darker pigmentation and an orange lateral line. Blacknose dace live in rocky streams and rivers where they feed upon small invertebrates and microscopic biological matter and provide forage for larger fish.
Margariscus, known as the pearl daces, is a genus of cyprinid fishes found in North America. There are currently two recognized species in this genus.
Thecachampsa is an extinct genus of tomistomine crocodylian. Fossils have been found from the eastern United States in deposits of late Oliogcene to Miocene age. Those named in the 19th century were distinguished primarily by the shape of their teeth, and have since been combined with T. antiquus. More recently erected species were reassigned from other tomistomine genera, although their assignment to Thecachampsa has since been questioned.
The finescale dace is a species of freshwater fish in the family Cyprinidae of order Cypriniformes. It is native to the northern portions of Minnesota.
The laurel dace is a species of freshwater minnow native to the U.S. state of Tennessee. It was first discovered in 1976. A very rare species, it has only been found in localized populations in six small streams on the Walden Ridge portion of the Cumberland Plateau in Tennessee. It is found in six streams: the Soddy, Horn, Cupp, Young's, Moccasin, and Bumbee Creeks, all of which drain into larger rivers that eventually feed the Tennessee River. It is believed to be extirpated from Laurel Creek, the only other stream where it was known to occur.
The redbelly tilapia, also known as the Zille's redbreast tilapia or St. Peter's fish, is a species of fish in the cichlid family. This fish is found widely in fresh and brackish waters in the northern half of Africa and the Middle East. Elsewhere in Africa, Asia, Australia and North America, it has been introduced as a food fish or as a control of aquatic vegetation. Where introduced, it sometimes becomes invasive, threatening the local ecology and species. The redbelly tilapia is an important food fish and sometimes aquacultured.
The mountain redbelly dace is a species of ray-finned fish in the genus Chrosomus. It is found in mountain and Piedmont regions of the Atlantic slope of North America from the Shenandoah River in Virginia, to the Neuse River drainage in North Carolina and the upper New River drainage in West Virginia, Virginia, and North Carolina.
The Leuciscidae, commonly known as true minnows, are a large family of the freshwater fish order Cypriniformes.
Laviniinae is a subfamily of the freshwater fish family Leuciscidae, which contains the true minnows. Members of this family are known as western chubs or the western clade (WC) of minnows. As the name suggests, most members of this family are found in western North America aside from Chrosomus, which is found in eastern North America.
