Catostomus is a genus of fish belonging to the family Catostomidae, commonly known as suckers. This genus of fish usually lives in freshwater basins. Most members of the genus are native to North America, but C. catostomus is also found in Russia.
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 beautiful shiner is a species of ray-finned fish in the family Cyprinidae. It is found in Mexico and Arizona and New Mexico in the United States. It is one of 22 species of Cyprinella found in North America.
The Gila chub is a species of ray-finned fish in the family Cyprinidae. It is found in Mexico and the United States. The Gila chub is closely related to the roundtail chub. This species is commonly found in association with the Gila topminnow, the desert and Sonora sucker, and the longfin and speckled dace.
The Yaqui chub is a species of freshwater fish in the family Cyprinidae. It is found in northern Mexico and the United States. The Yaqui chub is a medium-sized minnow fish that historically occurred in streams of Rios Matape, Sonora, and the Yaqui systems of Sonora, Mexico. It is one of the five species of the genus Gila in Arizona. The Yaqui chub is closely related to G. ditaenia, and G. orcutti ; and shares several physical characteristics with the G. orcutti, but proves different by having a black wedge near the base of the caudal fin.
The Little Colorado spinedace is a species of ray-finned fish in the family Cyprinidae. It is found only in Arizona in the United States.
The spikedace is an endangered species of ray-finned fish in the family Cyprinidae. It is found in Arizona and New Mexico in the United States. It lives in fast-moving streams.
Ictalurus pricei, the Yaqui catfish, is a species of North American freshwater catfish native to Mexico and Arizona.
The Gila longfin dace is a subspecies of the longfin dace found in Arizona. It is considered the nominate subspecies of the longfin dace.
The Yaqui longfin dace is a small fish of the American Southwest and northern Mexico, and considered a form of the longfin dace. It is often referred to as Agosia chrysogaster sp 1.
The Mexican stoneroller is a species of fish native to Arizona and Texas in the United States and parts of adjacent Mexico. It belongs to the carp family, Cyprinidae. The other species in this genus, Campostoma are morphologically similar.
The Sonora Sucker, Catostomus insignis, is a medium-sized catostomid fish with 16 other species in the genus scattered throughout North America. This species is remarkably similar in appearance to the Yaqui Sucker.
Catostomus latipinnis is a North American fish identified by its enlarged lower lips. It belongs to the genus Catostomus, commonly known as suckers. Historically, the flannelmouth sucker ranged in the Colorado River Basin, including parts of Wyoming, Utah, Colorado, New Mexico, Nevada, California, and Arizona; however, this species has been entirely extirpated from the Gila River Basin in Arizona.
The Little Colorado River sucker or Little Colorado sucker is a scientifically undescribed species of North American freshwater fish very similar to the flannelmouth sucker but without the flannelmouth's distinct fleshy lips. The Little Colorado sucker is native to the upper region of the Little Colorado River in Arizona, but was also introduced into the Salt River.
Catostomus discobolus jarrovii is a species of fish only found in Arizona and New Mexico in the United States.
The Modoc sucker is a rare species of freshwater fish native to northern California and southern Oregon. It grows to a length of about 7 in (18 cm) and becomes sexually mature at 4 in (10 cm). It feeds on algae, small invertebrates and detritus, and hides under stones, detritus and overhanging vegetation. It is found in only a few streams and is listed as an endangered species in California and the United States. Conservation measures have been put in place such as fencing the streams in which it lives from livestock. It was previously rated as "endangered" in 1973 by the International Union for Conservation of Nature, but this rating has now been changed to "near threatened", and the U.S. Fish and Wildlife Service removed the Modoc sucker from the federal list of endangered and threatened wildlife in 2016.
The desert sucker or Gila Mountain sucker, is a freshwater species of ray-finned fish in the sucker family, endemic to the Great Basin and the Colorado River Basin in the United States. It inhabits rapids and fast-flowing streams with gravelly bottoms. It is a bi-colored fish with the upper parts olive brown to dark green, and the underparts silvery-tan or yellowish. The head is cylindrical, tapering to a thick-lipped mouth on the underside. This fish can grow to 31 in (79 cm) in Arizona but is generally only about half this size elsewhere. There are three subspecies, found in different river basins, and some authorities allot this species its own genus Pantosteus.
The white sucker is a species of freshwater cypriniform fish inhabiting the upper Midwest and Northeast in North America, but it is also found as far south as Georgia and as far west as New Mexico. The fish is commonly known as a "sucker" due to its fleshy, papillose lips that suck up organic matter and aufwuchs from the bottom of rivers and streams.
The Rio Grande sucker is a North American freshwater fish in the family Catostomidae. It has a typical bottom-feeding phenotype and fills lower trophic levels alongside Rio Grande cutthroat trout and Rio Grande chub species. It is smaller sized in comparison to its other family members, with females being the larger between sexes. Coloration tends to benefit the species due to counter-shading patterns. It is endemic to the Rio Grande basin and was once common throughout. The species has maintained a population in New Mexico, Colorado, Arizona, and Northern Mexico, but has faced challenges from the pressure of non-native species, habitat loss, degradation, and a variety of other aquatic ecosystem changes. There is current pressure from environmental organizations to federally list the species as threatened or endangered.
