The common chub, also known as the European chub or simply chub, is a species of European freshwater ray-finned fish in the carp family Cyprinidae, that frequents both slow and moderate rivers, as well as canals, lakes and still waterbodies of various kinds.
The lake chub is a freshwater cyprinid fish found in Canada and in parts of the United States. Of all North American minnows, it is the one with the northernmost distribution. Its genus, Couesius is considered monotypic today. The genus was named after Elliott Coues, who collected the holotype specimen.
The chiselmouth is an unusual cyprinid fish of western North America. It is named for the sharp hard plate on its lower jaw, which is used to scrape rocks for algae. It is the sole member of the monotypic genus Acrocheilus and is a close relative of the Gila western chubs, and is known to hybridise with Ptychocheilus oregonensis.
The Alvord chub is a rare cyprinid fish endemic to the Alvord basin in southeastern Oregon and northwestern Nevada, U.S., known only from a few springs, streams and marshes in the Sheldon National Wildlife Refuge, and one location elsewhere.
The Utah chub is a cyprinid fish native to western North America, where it is abundant in the upper Snake River and throughout the Lake Bonneville basin.
The tui chub is a cyprinid fish native to western North America. Widespread in many areas, it is an important food source for other fish, including the cutthroat trout.
Lepidomeda is a genus of cyprinid fish, commonly known as the spinedaces, found in western North America. Of the four known species, one is extinct and two are threatened. They appear to be fairly close to the leatherside chub and the spikedaces, but the phylogeny and indeed the validity of the proposed "plagopterin" clade is insufficiently resolved.
The White River spinedace is a critically endangered cyprinid fish of Nevada, occurring only in the White River in the southeastern part of the state.
The blue chub is a cyprinid fish found in the Klamath River and Lost River drainages of far northern California and southern Oregon.
The arroyo chub is a species of cyprinid fish found only in the coastal streams of southern California, United States.
The relict dace is a cyprinid fish of the Great Basin of western North America. It is the sole member of its genus.
The White River springfish is a species of fish in the family Goodeidae, the splitfins. It is a rare species of the Great Basin of western United States, where it is endemic to isolated warm springs in the White River drainage of eastern Nevada.
The humpback chub is a federally protected fish that lived originally in fast waters of the Colorado River system in the United States. This species takes its name from the prominent hump between the head and dorsal fin, which is thought to direct the flow of water over the body and help maintain body position in the swift currents of the Colorado river. The body is almost entirely scaleless, retaining only about 80 mid-lateral scales along the lateral line. The fish is very streamlined, with a thin caudal peduncle and a deeply forked tail. The back is a light olive gray, the sides silver, and the belly white. The dorsal fin usually has nine rays, and the anal fin 10 or more. Maximum recorded length is 38 cm.
The Virgin spinedace is a cyprinid fish of the Virgin River, a tributary of the Colorado River in the United States.
The bonytail chub or bonytail is a cyprinid freshwater fish native to the Colorado River basin of Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming in the southwestern United States; it has been extirpated from the part of the basin in Mexico. It was once abundant and widespread in the basin, its numbers and range have declined to the point where it has been listed as endangered since 1980 (ESA) and 1986 (IUCN), a fate shared by the other large Colorado basin endemic fish species like the Colorado pikeminnow, humpback chub, and razorback sucker. It is now the rarest of the endemic big-river fishes of the Colorado River. There are 20 species in the genus Gila, seven of which are found in Arizona.
Macrhybopsis, the blacktail chubs, is a genus of cyprinid fish that are found in North America. There are currently 12 species in this genus.
Mylocheilus caurinus, the peamouth, peamouth chub, redmouth sucker or northwestern dace, is a species of freshwater ray-finned fish from the family Cyprinidae, the carps and minnows, that is found in western North America. It is the only species in its genus.
Securicula gora is a species of cyprinid fish found in Bangladesh, India, Pakistan and possibly in Nepal. It is the only species in its genus.
The southern leatherside chub is a species of freshwater ray-finned fish from the family Cyprinidae, the carps and minnows. It is endemic to Utah in the United States. It is found in slow-flowing pools and backwaters, usually over substrates consisting of mud or sand, of creeks and small to medium-sized rivers. Within Utah, this species is found on the southeastern margins of the Bonneville Basin; it has been recorded from the American Fork, Provo River, and Spanish Fork drainages of the Utah Lake Basin and the San Pitch River, East Fork Sevier River, Beaver River, and the lower, middle, and upper Sevier River drainages of the Sevier River Basin; it has now apparently been extirpated from the Provo River at Utah Lake and from the Beaver River. It is threatened by the fragmentation of its habitat caused by water abstraction for irrigation, damming, urbanization, and poor farming practices. It is also threatened by introduced predatory fish such as the brown trout.
The humpback mahseer is a species of freshwater ray-finned fish from the Indian endemic genus Hypselobarbus in the carp and minnow family Cyprinidae.
