Percidae
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains nearly 250 species in 12 genera. The perches and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family. Despite the widespread and speciose nature of this family, the vast majority of its species diversity is within the darters, which are restricted to eastern North America, and the majority of which have small ranges. Excluding the darters, this family contains only 20 species. In Europe, percids were likely a more ecologically dominant group in the past than now, with the immigration of cyprinids to Europe during the Miocene causing a decline in their importance.

Darter (fish)
Etheostomatinae is a species-rich subfamily of freshwater ray-finned fish, the members of which are commonly known as the darters. The subfamily is part of the Family (biology), family Percidae which also includes the perches, Gymnocephalus, ruffes and Sander (fish), pikeperches. The family is Endemism, endemic to North America. It consists of three to five different Genus, genera and well over 200 species. A common name for these fish in southern Indiana is pollywog. Characteristics Species within the Etheostomatinae are all small fish, mostly less than in length, and their bodies are slightly compressed or fusiform in shape. They have two pterygiophores between the first and second dorsal fins which do not have spines and a reduced swimbladder which may be completely lacking. The common name "darter" owes to the behavior of the fish, which dart around their benthic habitat. They are Sexual dimorphism, sexually dimorphic; most species have males with bright colors and patterning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Percarina
''Percarina'' is a genus of ray-finned fish in the family Percidae found in eastern Europe. They are characterised by having the first dorsal fin, having 9–11 spines and being widely separated from the second dorsal fin. Previously, they were treated as the only taxon in the Monotypy, monotypic subfamily Percarininae, but they are now placed with the perches and Gymnocephalus, ruffes in the Percinae. Species There are currently two recognised species in the genus: * ''Percarina demidoffii'' Alexander von Nordmann, Nordmann, 1840 (Common percarina) * ''Percarina maeotica'' Kuznetsov, 1888 (Azov percarina) References Percarina, Percidae Taxa named by Alexander von Nordmann Taxonomy articles created by Polbot {{Percidae-stub ...

Gymnocephalus
''Gymnocephalus'' is a genus of ray-finned fishes from the family Percidae, which includes the perches, pike-perches and darters. They are from the Western Palearctic area, although one species, '' Gymnocephalus cernua'' has been accidentally introduced to the Great Lakes region where it is regarded as an invasive species. They have the common name "ruffe" and resemble the true perches in the genus ''Perca'', but are usually smaller and have a different pattern. Characteristics The species within the genus ''Gymnocephalus'' have a number of characters in common including that their dorsal fins are not completely separate, they have enlarged canals extending from the lateral line on their heads, the preorbital bone covers the maxillary bone, presence of setiform or bristle-like teeth, having very few or no vomerine and palatine teeth and the possession of three paired bones in the neck, known as extrascapulars, in their lateral line system, of which, two are simple tubes.

Perciformes
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zander
The zander (''Sander lucioperca''), sander or pikeperch, is a species of ray-finned fish from the Family (biology), family Percidae, which also includes perch, Gymnocephalus, ruffe and Darter (fish), darter. It is found in freshwater and brackish habitats in western Eurasia. It is a popular game fish and has been introduced to a variety of localities outside its native range. It is the type species of the genus ''Sander''. Taxonomy The zander was first formally Species description, described in 1758 as ''Perca lucioperca'' by Carolus Linnaeus in volume 1 of the tenth edition of ''Systema Naturae'' and he gave the Type locality (biology), type locality as "European lakes". When Lorenz Oken (1779–1851) created the genus ''Sander (fish), Sander'' he made ''Perca lucioperca'' its type species. The zander is part of the European clade within the genus ''Sander'' which split from a common ancestor with the North American clade, which the walleye (''S. vitreus'') and the sauger (''S. ...

Sauger
The sauger (''Sander canadensis'') is a freshwater perciform fish of the family Percidae that resembles its close relative, the walleye. The species is a member of the largest vertebrate order, the Perciformes.Jaeger, Matthew. 2004. Montana's Fish Species of Special Concern: Sauger. Montana Cooperative Fisheries Research Unit. http://www.fisheriessociety.org/AFSmontana/SSCpages/Sauger%20Status.htm. (Accessed May 2011). It is the most migratory percid species in North America.Kuhn et al. 2008. Habitat Use and Movement Patterns by Adult Saugers from fall to Summer in an Unimpounded Small-River System. ''North American Journal of Fisheries Management''. 28: 360–367. American Fisheries Society. 2008. Saugers have two dorsal fins; the first is spiny and the posterior dorsal fin is soft-rayed. Their paired fins are in the thoracic position and their caudal fin is truncated, which means squared off at the corners, a characteristic of the family Percidae. Another physical characterist ...

Perch
Perch is a common name for freshwater fish from the genus ''Perca'', which belongs to the family Percidae of the large order Perciformes. The name comes from , meaning the type species of this genus, the European perch (''P. fluviatilis''). Many species of freshwater game fish more or less resemble perch, but belong to different genera. In fact, the exclusively saltwater-dwelling red drum (which belong to a different order Acanthuriformes) is often referred to as a "red perch", though by definition perch are freshwater species. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae. Species Most authorities recognize three species within the perch genus: * The European perch (''P. fluviatilis'') is primarily found in Europe, but a few can also be found in South Africa, and even as far east on the Southern hemisphere as Australia. This species is typically greenish in color with dark vertical ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruffe
The ruffe (''Gymnocephalus cernua''), also known as the Eurasian ruffe or pope, is a freshwater fish found in temperate regions of Europe and northern Asia. It has been introduced into the Great Lakes of North America as an invasive species and is causing unfortunate results as it is reproducing faster than other species. Its common names are ambiguous – "ruffe" may refer to any local member of its genus '' Gymnocephalus'', which as a whole is native to Eurasia. Description The ruffe's colors and markings are similar to those of the walleye, an olive-brown to golden-brown color on its back, paler on the sides with yellowish white undersides. The ruffe can reach up to in length, but is usually around half that size. It is a very aggressive fish for its size. The ruffe also has a large, spiny dorsal fin which is likely distasteful to its predators. It also has two fins on top, the front fin has hard and sharp spines, the back fin has soft spines called rays. The most obviou ...

Candy Darter
''Etheostoma osburni'', the candy darter or finescale saddled darter, is a species of fish in the family Percidae, a member of the group known as darters. This species is endemic to the eastern United States where it is known only from the Kanawha River system in the states of Virginia and West Virginia. Description and natural history ''E. osburni'' can reach a length of , though most only reach about . This species has a lifespan of up to three years. It spawns in April and May.NatureServe. (2017)''Etheostoma osburni''.NatureServe Explorer V.7.1 Accessed 8 August 2017. It is an invertivore, feeding on aquatic insect larvae and water mites. Habitat and geographic distribution ''E. osburni'' lives in a system of rivers, streams, and creeks in the central Appalachian Mountains. It can be found in rapid riffles in rocky riverbed habitat. It occurs in cold, cool, and warm waters, as long as the substrate is rocky and the water is clear. It tolerates fast currents. Conservation '' ...

Walleye
The walleye (''Sander vitreus'', Synonym (taxonomy), synonym ''Stizostedion vitreum''), also called the walleyed pike, yellow pike, yellow pikeperch or yellow pickerel, is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European zander, also known as the pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a color morph that was once found in the southern Ontario and Quebec regions, but is now presumed extinct. However, recent genetic analysis of a preserved (frozen) 'blue walleye' sample suggests that the blue and yellow walleye were simply phenotypes within the same species and do not merit separate taxonomic classification. In parts of its range in English-speaking Canada, the walleye is known as a pickerel, though the fish is not related to the true Esox, pickerels, which are members of the family ''Esocidae''. It is also sometimes c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
