The loach minnow is a species of freshwater fish. It is a member of the carp family of order Cypriniformes. It occurs in streams and small rivers throughout the Gila River and San Pedro River systems in Arizona, New Mexico, and Sonora; it is now considered extinct in Mexico.
The Banff longnose dace was a diminutive version of the eastern longnose dace, its range restricted to a small marsh fed by two hot springs on Sulphur Mountain in Banff National Park in Banff, Alberta, Canada.
The aurora trout, Salvelinus fontinalis timagamiensis, is a variant or subspecies of the brook trout native to two lakes in the Temagami District of Ontario, Canada. The existence of the fish was brought to the attention of the angling world by four American anglers who were taken by Archie King of Latchford, Ontario, into Ontario's Lady Evelyn River system in 1923. Recognizing the fish as different or unique, the anglers took a specimen back to the Carnegie Museum in Pittsburgh, in the United States, where Dr. Arthur W. Henn was asked to identify the fish. He wrote about the fish in 1925 wherein he and Rinckenbach identified it as a distinct species, Salvelinus timagamiensis, but since a seminal re-examination of the material by Sale in 1967, taxonomists now agree the fish is, in a fact, at most a subspecies of the brook trout, named Salvelinus fontinalis timagamiensis. Genetic data has not yet supported its taxonomic distinction.
The longnose dace is a freshwater minnow native to North America. Rhinicthys means snout fish and cataractae means of the cataract. Longnose dace are small, typically less than 100 mm and characterized by their fleshy snout that protrudes past the mouth. They are well adapted for living on the bottom of fast-flowing streams among stones. Longnose dace eat algae and aquatic insects and are important forage minnows for larger predatory fish.
The southern brook lamprey is a lamprey found in the Southern United States including Arkansas, Louisiana, Mississippi, Alabama, and Georgia. It is a jawless fish with a sucking mouth on one end of it. It can appear to be a small eel, since it is rarely longer than one foot in length.
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 speckled dace, also known as the spotted dace and the carpita pinta, is a member of the minnow family. It is found in temperate freshwater in North America, from Sonora, Mexico, to British Columbia, Canada.
The blackstripe topminnow, Fundulus notatus, is a small freshwater fish in the family Fundulidae, found in central North America.
The redside dace is a species of ray-finned fish in the family Cyprinidae, found in the United States and Canada. It is unique among minnows, being the only species to routinely feed on flying insects by leaping from water. Thus, it acts as a conduit for nutrient transfers between terrestrial and aquatic environments. The species can be used as an ecosystem health indicator, as it is sensitive to environmental disturbances.
The carmine shiner is a freshwater fish species. In Manitoba, it was once known as the rosyface shiner. Based mostly on zoogeographic data, it is currently classified as a distinct species within the rosyface shiner species complex. The carmine shiner is a member of the Minnow family, Cyprinidae. It has the following characteristics and distinguishing features:
Eastern blacknose dace is a species of ray-finned fish in the genus Rhinichthys. Its name originates from the Old French word "dars" which is the nominative form of the word "dart" in reference to their swimming pattern. The western blacknose dace formerly was considered conspecific. While morphologically the two species are not significantly different, they are allopatric. The eastern blacknose dace is found across the southeast portion of Canada and down along the United States' east coast. It is dark brown to olive on its dorsal surface and silvery white below, the two shades separated by the darkly pigmented lateral line. In the breeding season, males develop darker pigmentation and an orange lateral line. Blacknose dace live in rocky streams and rivers where they feed upon small invertebrates and microscopic biological matter and provide forage for larger fish.
Western blacknose dace is a common species of ray-finned fish belonging to the family Cyprinidae and the genus Rhinichthys. Western blacknose dace have tan to dark brown backs, lighter sides, and cream colored undersides. Dark blotches are sporadically scattered across their sides and backs. A distinctive dark colored mid-lateral stripe from the tip of the snout to the caudal peduncle is present. The snout is relatively long and they have a slightly sub-terminal mouth. The stripe is dark brown in females and is a rusty pink color in males during spawning season. The lateral stripe is more pronounced and the caudal spot is present in juveniles. Similar to other species of dace the western blacknose dace give the illusion of having no scales but in actuality the scales are so small they are hard to see. Western blacknose dace are typically 2-3 inches long but can grow to as long as 4 inches. They have a forked tail, single dorsal fin with 8 rays and no spines, a pelvic fin on the abdominal, no adipose fin, and an anal fin with 7 rays and no spines.
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.
The gilt 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 can be found in a number of states in the Mississippi River drainage of the United States although it has been extirpated from some river systems in which it was at one time present, mostly due to siltation and pollution problems. Males are more colorful than females and can grow to a length of about 9 cm (3.5 in). It is a benthic fish that feeds primarily on small aquatic insect larvae. Males form territories during the breeding season in late spring and early summer. Spawning typically takes place at the upper ends of riffles with sandy and gravelly bottoms interspersed with larger cobbles. Some organisations are endeavouring to conserve populations of the gilt darter and re-introduce it to states where the fish has been extirpated but suitable habitat still exists.
The laurel dace is a species of freshwater minnow native to the U.S. state of Tennessee. It was first discovered in 1976. A very rare species, it has only been found in localized populations in six small streams on the Walden Ridge portion of the Cumberland Plateau in Tennessee. It is found in six streams: the Soddy, Horn, Cupp, Young's, Moccasin, and Bumbee Creeks, all of which drain into larger rivers that eventually feed the Tennessee River. It is believed to be extirpated from Laurel Creek, the only other stream where it was known to occur.
The inland riffle sculpin is a species of fish in the family Cottidae. It is found in the United States, inhabiting the lower Columbia River drainage in Washington, to Morro Bay in California. It is also found in the Puget Sound drainage in Washington. It reaches a maximum length of 11.0 cm. It prefers rocky riffles of headwaters and creeks.
