Margariscus, known as the pearl daces, is a genus of leusiscid fishes found in North America. There are currently two recognized species in this genus. Margariscus comes from the Greek word margariskos, meaning pearl.
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 fish called "daces", belongs to the family Cyprinidae, mostly in subfamily Leuciscinae.
The common dace is a species of freshwater and brackish water ray-finned fish from the family Cyprinidae which is native to Europe but which has been introduced to other parts of the world. It is a quarry species for coarse anglers.
Leuciscus is a genus of fish belonging to the family Cyprinidae. They are inland water fishes commonly called Eurasian daces. The genus is widespread from Europe to Siberia. Species broadly distributed in Europe include the common dace Leuciscus leuciscus and the ide L. idus.
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 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.
Musreau Lake is a Mesotrophic lake northwestern Alberta. The closest city is Grande Prairie, Alberta. It has Six inlet creeks and outflows out to Musreau Creek that links to the Kakwa River, then the Smoky River. A small lake directly to the west is named Little Musreau Lake connected by a short unnamed creek, both are within the Musreau Lake Provincial Recreation Area established in 1978.
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.
Cirrhinus molitorella is a species of ray-finned fish in the genus Cirrhinus found mainly in southern China and Vietnam.
The longfin dace is a leuciscid fish that is found in western North America in the United States and Mexico. It is the only member of its genus. The Gila longfin dace is considered the nominate subspecies. The Yaqui longfin dace is considered a form.
The Allegheny pearl dace is a species of cyprinid fish. It is demersal, freshwater fish, with a dark green back and silvery body. This species is omnivorous, consuming algae, as well as arthropods. M. margarita's range spans southern Canada and the northern United States. While not considered endangered at the federal level in the United States, several states either consider this species endangered or threatened; it faces threats of habitat destruction and invasive species.
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.
Chrosomus is a genus of small cyprinid fish found in freshwater habitats in the eastern half of the United States and Canada. There are currently seven recognized species in this genus. They have sometimes been included in Phoxinus. They are the only members of the predominantly western subfamily Laviniinae that are found in eastern North America.
Clinostomus is a genus of cyprinid fish that occur in eastern North America. There are two species in this genus.
The northern pearl dace is a freshwater ray-finned fish in the family Cyprinidae, the carps and minnows. It occurs in Atlantic, Hudson Bay, Great Lakes, and Mississippi River basins in the northern United States and Canada. Its preferred habitat is cool, clear headwater streams, bog drainage streams, ponds and small lakes, and in stained, peaty waters of beaver ponds, usually over sand or gravel.
Plagopterinae is a subfamily of the freshwater fish family Leuciscidae, which contains the true minnows. Members of this family are known as creek chubs or the creek chub-plagopterin (CC-P) clade of minnows. All members of this family are found in North America, and it includes among the northernmost-distributed of all North American minnows, the lake chub.
