The peppered chub (Macrhybopsis tetranema), also known as the Arkansas River speckled chub, is a freshwater ray-finned fish in the family Cyprinidae, the carps and minnows. It historically occurred throughout the Arkansas River drainage, but today is found in the Ninnescah River, a small portion of the Arkansas River in Kansas and the South Canadian River between Ute and Meredith reservoirs in New Mexico and Texas. Its preferred habitat is shallow channels of large, permanently flowing, sandy streams, and prefers currents over a substrate of clean, fine sand. [2]
On February 25, 2022, the peppered chub was added to the endangered species list. [3]
The thicktail chub was a type of minnow that inhabited the lowlands and weedy backwaters of the Sacramento and San Joaquin Rivers in the Central Valley of California. It was once abundant in lowland lakes, marshes, ponds, slow-moving stretches of river, and, during years of heavy run-off, the surface waters of San Francisco Bay. The thicktail chub was one of the most common fish in California. Within Native American middens it represented 40% of the fish.
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.
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. 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 sturgeon chub is a species of ray-finned minnow fish in the family Cyprinidae. It is found only in the United States. It is a species of concern in the Charles M. Russell National Wildlife Refuge in Montana.
Macrhybopsis, the blacktail chubs, is a genus of cyprinid fish that are found in North America. There are currently 12 species in this genus.
The sicklefin chub is a species of ray-finned minnow fish in the family Cyprinidae. It is found only in the United States. It is one of the 324 fish species found in Tennessee, and is a species of concern in the Charles M. Russell National Wildlife Refuge in Montana.
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.
Theliderma intermedia, the Cumberland monkeyface pearly mussel or Cumberland monkeyface, is a species of freshwater mussel in the family Unionidae, the river mussels. This aquatic bivalve mollusk is native to Tennessee and Virginia in the United States. Historically widespread in the upper Tennessee River system, it populations have been reduced by habitat destruction and pollution. It now only occurs in two tributaries: the Duck and Powell Rivers. It is a federally listed endangered species.
The speckled chub is a species of freshwater fish in the family Cyprinidae of the order Cypriniformes, which also includes carps, suckers, and loaches.
Bigeye chub is a species of freshwater fish in the carp family (Cyprinidae).
The silver chub is a species of freshwater fish of the family Cyprinidae found in North America.
The gravel chub, also known as the spotted chub, is a freshwater minnow from the family Cyprinidae. This species of fish has a spotted distribution inhabiting various small rivers and streams in North America. The gravel chub requires a highly specific clean habitat making it vulnerable to various types of pollutants and in need of conservation efforts.
The Ozark chub is a species of ray-finned fish in the family Cyprinidae. It is found in mountain streams in the Ozarks in Missouri and Arkansas. It is currently petitioned for federal protection under the Endangered Species Act.
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.
The shoal chub is a freshwater ray-finned fish in the family Cyprinidae, the carps and minnows. It occurs in Mississippi River drainages from eastern Ohio to southern Minnesota and Nebraska south to Louisiana. Its preferred habitat is sand and gravel runs of small to large rivers.
The burrhead chub is a freshwater ray-finned fish in the family Cyprinidae, the carps and minnows. It occurs in the Colorado, Guadalupe, and San Antonio river drainages in Texas. Its preferred habitat is sand and gravel runs of small to large rivers.
