The Bayou darter is a rare 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 endemic to western Mississippi in the United States, where it is found only in Bayou Pierre and its tributaries. Its typical habitat is fast-flowing creeks and streams, in riffles and in areas between riffles with firm gravel bottoms. It feeds on small insects and their larvae. Breeding probably takes place twice a year, in spring and late summer. The population of this fish is declining due to loss of suitable habitat. This is caused by siltation and pollution, particularly erosion caused by changes in land use. The International Union for Conservation of Nature has assessed its conservation status as being "endangered".
The vermilion 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 endemic to the southern United States, where it only is found in Turkey Creek in Jefferson County, Alabama, part of the Mobile Bay drainage basin. It was first described by Herbert Boschung in 1992, who was the curator of ichthyology at the University of Alabama, along with biologist Richard Mayden and scientific illustrator Joseph Tomelleri. On December 7, 2010, the US Fish and Wildlife Service designated 13 mi (21 km) of Turkey Creek watershed as critical habitat for the darter. According to the IUCN, the population of this fish is declining.

The Cumberland snubnose 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. This species is found in the middle Cumberland River drainage in Tennessee, Kentucky, Virginia, North Carolina, Georgia, and Alabama. It is absent in reaches above the Big South Fork, rare in North Carolina, and absent in western tributaries of the Tennessee River. While research on the ecology of E. atripinne is not extensive, what is known is they are usually found in small to medium freshwater streams in gravel riffle areas where their eggs can attach to the substrate and be left unguarded. E. atripinne can be found within a wide range of depths in its environment, leading its being classified as benthopelagic. While its global status is secure, the American Fisheries Society labels it with a status of “Special Concern”.

The corrugated 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 endemic to the eastern United States only known from Caney Fork, Tennessee, where it has been shown to have as many as five subgroups. They are active hunters which prey on insects, fry, and possibly young snails. Multiple species and subspecies of these darters can coexist where substrate is varied, so this must be carefully preserved to accommodate many similar species. With the warming of spring, E. basilare enters its breeding cycle and males develop their dimorphic coloration. Like most darters, it hugs the stream bed, using its body shape and fin posture to maintain its position.

It is endemic to the eastern United States. It is found in small rivers and streams in the states of Tennessee, Ohio, Kentucky, Illinois, Alabama, Georgia, and Mississippi. Males are a golden-orange color with black barring on the fins, and grow to a length of about 2.8 in (7 cm). This fish feeds on midge larvae and other small invertebrates. It breeds in the spring; eggs are attached to the substrate, often under slab rocks, where they are guarded by the male. The population trend of this fish seems to be stable and it is a common species with numerous sub-populations over a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The goldstripe 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 endemic to the southeastern United States where it is found in Gulf Slope streams from the Colorado River drainage in Texas to the Flint River in Georgia, the Atlantic Slope in Ocmulgee River system, Georgia, and the Mississippi embayment north as far as southeastern Missouri and western Kentucky. It is typically found in small springs, streams, and creeks with aquatic and marginal vegetation and detritus. The female spawns on multiple occasions between about mid-March and June, sticking the adhesive eggs to plants, gravel and the sides of rocks.

It forages on the bottom for the aquatic larvae of midges, blackfly, mayfly and caddisfly, as well as isopods and amphipods. Spawning takes place in spring, the selected sites often being the upper stretches of riffles with sandy and gravelly bottoms interspersed with larger cobble. Reproductive success is high in this species. No particular threats have been identified, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The wounded 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 endemic to the eastern United States. Its range includes the upper Tennessee River drainage, western Virginia, western North Carolina, and eastern Tennessee. Its typical habitat is among boulders or coarse rubble and cobble, often with overhanging ledges, in medium to large slow-moving rivers. It feeds on small insect larvae, especially midge larvae. Spawning occurs when the water warms up in late spring. Females deposit clutches of adhesive eggs on the underside of rock ledges or slabs, and the male guards the nest. The population trend of this fish seems to be decreasing slowly but it is a relatively common species with numerous sub-populations, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". The greatest threat comes from impoundment, and a management plan is in place, including captive breeding.
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.
Nothonotus is a genus or subgenus 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 endemic to the southeastern United States. First proposed as a sub-genus of Etheostoma in 1988, there is still debate regarding the appropriate taxonomic rank of Nothonotus in the literature. Darter species comprise more than 180 of the Percidae taxa.
