The desert sucker or Gila Mountain sucker (Catostomus clarkii), 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.

Description

Desert suckers are bicolored; the back and upper sides are darker, olive-brown to dark green, and the belly and lower sides are deep-yellow to silvery tan. The scales on the upper half of the body have dark spots which form faint dashed lines. Their head is cylindrical, tapering to a blunt face with the lower lip about three times as thick as upper lip. The mouth is on the underside (ventral) of the face and is proportionately large. The dorsal fin of the desert sucker has 10 to 11 rays. The adult lengths range from 4 to 16 inches (100 to 410 mm) in smaller streams, but up to 31 inches (790 mm) in Arizona. [3] Their weight ranges from 4 to 65 ounces (110–1,840 g).

Distribution

The desert sucker is found in Nevada, Utah, Arizona and New Mexico. [2] [4] The desert sucker occurs in the lower Colorado River basin, below the Grand Canyon, particularly in the Gila River, and above the Grand Canyon in streams in the Virgin River basin, the White River basin and others. The total range area of the desert sucker is estimated at 128,000 km2 (49,000 sq mi). [5]

Habitat

Desert suckers prefer ripply waters, rapids and flowing streams with gravelly bottoms.

Reproduction

Desert suckers reach maturity in their second year. [6] Spawning occurs in winter and spring from January through May. [7]

Subspecies

Three subspecies have been identified: the White River desert sucker, Catostomus clarkii intermedius [8] (sometimes known as White River mountain sucker, Pantosteus intermedius), [9] Virgin River desert sucker, Catostomus clarkii utahensis, [8] [10] and the Meadow Valley Wash desert sucker, Catostomus clarkii (unnamed). [8] [11]

Some ichthyologists regarded these as members of the genus Pantosteus, [9] but later authors regard Pantosteus as a subgenus of Catostomus. [12] There are suggestions of hybridization between Catostomus clarkii and Catostomus insignis. [9]

<span class="mw-page-title-main">Mountain sucker</span> Species of fish

The mountain sucker is a sucker found throughout western North America, on both sides of the Rocky Mountains, including the upper Missouri River, Columbia River, Sacramento River, and Colorado River. It is not limited to higher altitudes but is known from locations as high as 2,800 m (9,200 ft). It is a slender, streamlined fish typically under 20 cm (8 in) in length. It is generally olive green or brown above, with pale underparts, and breeding males have a lateral red-orange band and fins suffused with the same color. It is mainly herbivorous, feeding on algae and diatoms. Breeding takes place in late spring and early summer in gravelly riffles in small streams.

<span class="mw-page-title-main">Utah sucker</span> Species of fish

The Utah sucker is a species of freshwater fish in the family Catostomidae found in the upper Snake River and the Lake Bonneville areas of western North America where it lives in a wide range of habitats. It is a large sucker growing up to 25 in (64 cm) long. It is generally blackish above, vaguely streaked and blotched, with a white belly. A narrow rosy lateral band extends backwards from the head. The mouth has thick lips and is on the underside of the head. Some populations are in decline because of anthropogenic factors but overall this fish is not threatened.

<span class="mw-page-title-main">Razorback sucker</span> Species of fish

The razorback sucker is a suckerfish found in rivers and lakes in the southwestern United States and formerly northwestern Mexico. It can grow to 91 cm (3 ft) in length and is recognisable by the keel between its head and dorsal fin. It used to inhabit much of the Colorado River Basin but commercial fishing, river damming, and habitat loss have caused great declines in populations. It is now restricted to the Colorado River upstream of the Grand Canyon and to four reservoirs, Lake Mead, Lake Mohave, Lake Havasu, and Lake Powell.

The Colorado pikeminnow is the largest cyprinid fish of North America and one of the largest in the world, with reports of individuals up to 6 ft (1.8 m) long and weighing over 100 pounds (45 kg). Native to the Colorado River Basin of the southwestern United States and adjacent Mexico, it was formerly an important food fish for both Native Americans and European settlers. Once abundant and widespread in the basin, its numbers have declined to the point where it has been extirpated from the Mexican part of its range and was listed as endangered in the US part in 1967, a fate shared by the three other large Colorado Basin endemic fish species: bonytail chub, humpback chub, and razorback sucker. The Colorado pikeminnow is currently listed as vulnerable by the IUCN, while its NatureServe conservation status is "critically imperiled".

<i>Catostomus latipinnis</i> Species of fish

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.

<span class="mw-page-title-main">River carpsucker</span> Species of fish

The river carpsucker is a freshwater fish found in the inland United States and northern Mexico. This species has a slightly arched back and is somewhat stout and compressed. While the fins are usually opaque, in older fish they may be dark yellow. It is distributed along the Mississippi River basin from Pennsylvania to Montana. The river carpsucker, like most suckers, is a bottom feeder and obtains its nutrients from algae, microcrustaceans, and other various tiny planktonic plants and animals found in silty substrates. Like its congener, the quillback, the river carpsucker is long-lived, with a lifespan of more than 45 years. It begins to reproduce typically in late spring, and the female usually releases more than 100,000 eggs. After releasing and fertilizing their eggs, all parental care is ended.

<span class="mw-page-title-main">White sucker</span> Species of fish

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.

<span class="mw-page-title-main">Rio Grande sucker</span> Species of fish

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.
