The bigmouth chub (Nocomis platyrhynchus) is a species of fish native to West Virginia.
The bigmouth chub has a body length that averages 15.2 centimeters and can reach up to 21.4 centimeters. [2] The chub has an elongated body that is nearly circular in cross section. It has a triangular head and a pointy snout. The mouth of the chub is medium-sized and has a barbell on each side. [3]
The chub has eight dorsal fin rays, eight pelvic fin rays, seven anal fin rays, and fourteen to seventeen pectoral fin rays. [3]
The fish is covered with cycloid scales. The scales on the chub's dorsal section, or top of the fish, have brown pigment. [3] The scales on the ventral section, or bottom of the fish, lack pigment and are white in appearance. [3]
It is generally found in pools and fast moving waterways in North Carolina, Virginia, West Virginia. Many populations are located in the New River of West Virginia and its tributaries. The fish prefers clear rivers with warm temperatures. The substrate of rivers inhabited by the bigmouth chub ranges from pebbles to boulders. It avoids the shallowest parts of rivers and waterways, and tends to be found near substrate. [1]
The chub reproduces through spawning. Spawning occurs in gravel spawning mounds created by the male. The mounds tend to be located in areas with small to large-sized gravel and with medium water speeds. [1]
It is ranked as being of least concern by the International Union for Conservation of Nature. The fish is not seen as at risk for extinction due to its large and stable population size, large habitat range and a lack of wide-scale threats to its survival. [1]
The emerald shiner is one of hundreds of small, silvery, slender fish species known as shiners. The identifying characteristic of the emerald shiner is the silvery emerald color on its sides. It can grow to 3.5 inches in length and is found across North America from Canada to the Gulf of Mexico, commonly in large, deep lakes and rivers, though sometimes in smaller bodies of water as well. It feeds on small organisms such as zooplankton and insects, congregating in large groups near the surface of the water. It is a quite common fish and is often used as a bait fish.
The Roanoke logperch is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is found in the Roanoke and Chowan drainages in Virginia and North Carolina in the United States. They inhabit low and moderate-gradient streams and rivers in warm, clear water in mostly unsilted gravel and rubble in runs, pools, and riffles. They are primarily insectivorous. This fish is a federally listed endangered species.
The Tennessee shiner is a species of fish in the family Cyprinidae, the carps and minnows. It is native to the southeastern United States.
The Tennessee dace is a species of ray-finned fish in the family Cyprinidae. It is found only in the United States; particularly in northeast Tennessee and southwest Virginia, and parts of extreme northwest Georgia. Until recently, they were considered a subspecies of mountain redbelly dace. They are commonly found in East Tennessee in spring fed first-order streams, often in silt and fine gravel pools, or undercut banks. These streams usually do not exceed two meters in width.
The Sandhills chub is a species of freshwater fish in the family Cyprinidae of order Cypriniformes. There are 4 species of Semotilus, 2 of which occur in South Carolina. This fish is found only in North Carolina and South Carolina. The Sandhills chub is predominately found in the Carolina Sandhills and some areas of Cape Fear, Pee Dee and Santee river drainages. It is characterized by its robust body, large head and lack of a dark blotch or smudge on their dorsal fin which is present on the closely related Creek Chub. The Sandhills chub has fine scales, a pinkish body and can be up to 9.4 inches.
The hornyhead chub is a small species of minnow in the family Cyprinidae of order Cypriniformes. It mainly inhabits small rivers and streams of the northern central USA, up into Canada. The adults inhabit faster, rocky pools of rivers.
Semotilus atromaculatus, known as the creek chub or the common creek chub, is a small minnow, a freshwater fish found in the eastern US and Canada. Differing in size and color depending on origin of development, the creek chub can usually be defined by a dark brown body with a black lateral line spanning horizontally across the body. It lives primarily within streams and rivers. Creek chubs attain lengths of 2-6 inches with larger specimens of up to 12 inches possible. The genus name Semotilus derives from the Greek word sema, and atromaculatus comes from the Latin word "black spots".
The headwater chub is a species of fish in the family Cyprinidae. It is found in Arizona and New Mexico.
The spotfin shiner is a species of ray-finned fish in the family Cyprinidae. It is a small sized freshwater fish found abundantly in many watercourses of North America.
The longnose shiner is a species of ray-finned fish in the genus Notropis.
The speckled chub is a species of freshwater fish in the family Cyprinidae of the order Cypriniformes, which also includes carps, suckers, and loaches.
The redtail chub is a freshwater fish found in the U.S. states of Tennessee and Kentucky.
The river chub is a minnow in the family Cyprinidae. It is one of the most common fishes in North American streams.
Percina phoxocephala, the slenderhead darter, is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is found in North America in the central Ohio and Mississippi River basins, to northeastern South Dakota and the Lake Winnebago system in Wisconsin, and as far south as the Red River in eastern Oklahoma and northeast Texas, typically in small to medium size rivers. It is a colorful species, with an average length of 6 to 9 centimeters. Males take on a deeper hue during the breeding season. It feeds on insect larvae and other small invertebrates, and spawns between April and June. It is a common fish with a very wide range and the International Union for Conservation of Nature has classified its conservation status as being of "least concern".
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.
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 flame chub is a species of freshwater fish in the family Cyprinidae found only in the United States. Its range broadly follows the Tennessee River from above Knoxville, Tennessee, to the mouth of the Duck River. Historically the species was found in Kentucky, Tennessee, Alabama and Georgia. The preferred habitat of flame chub is in small flowing streams often associated with springs.
The bluehead chub is a cyprinid native to North America. Its name is due to its appearance, as breeding males have a blue head. Adult bluehead chubs are, on average, between 70 and 160 mm in length. They have a robust body with uniformly large scales. The scales are present on the belly and breast. They have a pored body, a weakly falcate pectoral fin, and pharyngeal teeth. They have a large mouth, small eyes, and a terminal barbel. Other characteristics include a darkened lateral band, spot on the caudal fin, and red coloration of the fins and iris of the eyes.
