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 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.

The Oregon chub is a species of ray-finned fish in the family Cyprinidae. It is endemic to Oregon in the United States. From 1993 to 2015 it was a federally listed threatened species.Their scales are relatively large, with less than 40 on their lateral line.

The gravel chub, also known as the spotted chub, is a freshwater minnow from the family Cyprinidae.

The gravel chub requires a highly specific clean habitat making it vulnerable to various types of pollutants and in need of conservation efforts.
The Rio Grande chub is a cyprinid fish endemic to the United States. It inhabits the upper Rio Grande and Pecos River systems in Colorado, New Mexico and Texas. The Rio Grande chub is native to most of its current range including all three of the states it can be found in. There are non-native populations that currently inhabit Coyote Creek, the Mora River, the Sapello River and other areas in New Mexico. There are currently no studies showing how the Rio Grande chub is impacting waterways in its non-native range. It has also been proposed that this fish is native to the Canadian River in New Mexico but this has not been proven. It is possible it was introduced there. Natural hybridization can occur between the Rio Grande chub and the longnose dace.
The prairie chub is a freshwater ray-finned fish in the family Cyprinidae, the carps and minnows. It occurs in the upper Red River drainage in Oklahoma and Texas. Its preferred habitat is sand and gravel runs of creeks and small to large rivers.
