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 more than 200 species in 11 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.
The family is characterised by having the dorsal fin split into two [2] which are normally separated or have a narrow connection, although this is wider in the genus Zingel, [3] the front section contains the spines and the rear section contains the soft rays. [2] The anal fin contains 1 or 2 spines, if there is a second spine it is typically weak. The pelvic fins are placed on the thorax and have a single spine and 5 soft rays. They also have skeletal synapomorphies. [3] The maximum size attained is 100 centimetres (39 in) in the zander (Sander lucioperca) [4] but most of the species in the family are much smaller. [3] Their scales are ctenoid and their bodies are normally somewhat elongate. [5]
The 5th Edition of Fishes of the World classifies the Percidae into five subfamilies [3] and Fishbase recognises 239 species in 11 genera. [4] [1] [6]
Percina is a genus of small freshwater ray-finned fish, classified within the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches from North America. Along with similar fishes in certain other genera, members of Percina are commonly called "darters". More specifically, the genus as a whole is known as roughbelly darters, while certain species of Percina with a pattern of vertical bars on the flanks are called logperches.
The Moronidae is a family of percomorph fishes, commonly called the temperate basses, in the order Moroniformes. These fishes are found in the freshwaters of North America and the coastal waters of the North Atlantic.
The Carangidae are a family of ray-finned fish that includes the jacks, pompanos, jack mackerels, runners, trevallies, and scads. It is the largest of the six families included within the order Carangiformes. Some authorities classify it as the only family within that order but molecular and anatomical studies indicate that there is a close relationship between this family and the five former Perciform families which make up the Carangiformes.
Sebastes is a genus of marine ray-finned fish belonging to the subfamily Sebastinae part of the family Scorpaenidae, most of which have the common name of rockfish. A few are called ocean perch, sea perch or redfish instead. They are found in the Atlantic and Pacific Oceans.
Hexagrammidae, the greenlings, is a family of marine ray-finned fishes belonging to the suborder Cottoidei in the order Scorpaeniformes. These fishes are found in the North Pacific Ocean.
Sander is a genus of predatory ray-finned fish in the family Percidae, which also includes the perches, ruffes, and darters. They are also known as "pike-perch" because of their resemblance to fish in the unrelated Esocidae (pike) family. They are the only genus in the monotypic tribe Luciopercini, which is one of two tribes in the subfamily Luciopercinae,
Romanichthys is a genus of ray-finned fish, one of two genera in the tribe Romanichthyini, which along with the tribe Luciopercini, forms the subfamily Luciopercinae of the family Percidae, alongside the perches, ruffes, and darters. The genus contains the single species Romanichthys valsanicola, known as the sculpin-perch, asprete, or Romanian darter.
Stichaeidae, the pricklebacks or shannies, are a family of marine ray-finned fishes in the suborder Zoarcoidei of the order Scorpaeniformes. Most species are found in the North Pacific Ocean with a few in the North Atlantic Ocean.
Ammocrypta is a genus of freshwater ray-finned fish, commonly known as the sand darters, which is classified in the subfamily Etheostomatinae, part of the family Percidae which also includes the perches, ruffes and pikeperches. The species in the genus occur in eastern North America in Canada and the continental United States.
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.
Percarina is a genus of ray-finned fish in the family Percidae found in eastern Europe. The genus is the only taxon in the monotypic subfamily Percarininae, which is characterised by having the first dorsal fin, having 9-11 spines and being widely separated from the second dorsal fin. They are thought to be closely related both to the perches of the genus Perca and to the ruffes of the genus Gymnocephalus.
Bellator militaris, the horned sea robin, is a species of marine ray-finned fish belonging to the family Triglidae, the sea robins. This fish is found in the western Atlantic Ocean.
Bellator is a genus of marine ray-finned fishes belonging to the family Triglidae, one of two genera belonging to the subfamily Prionotinae, the sea robins. These fishes are found in the Western Atlantic Ocean and eastern Pacific Ocean, in the waters off both North and South America.
Zingel zingel, the zingel, is a species of freshwater ray-finned fish in the family Percidae. It is found in fast-flowing streams in southeastern Europe. It is the type species of the genus Zingel.
The Luciopercinae is a subfamily of ray-finned fish, classified within the family Percidae, the subfamily includes the pike-perches and zingels. The pike-perches of the genus Sander have an Holarctic distribution while the zingels of the tribe Romanichthyini are found in Europe. They are largely freshwater species but some can be found in brackish water.
Romanichthyini is a tribe of freshwater ray-finned fish which is one of two tribes in the subfamily Luciopercinae, which in turn is classified under the family Percidae, the family also includes the perches, pikeperches, ruffes and darters.
Etheosomatinae 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 Percidae which also includes the perches, ruffes and pikeperches. The family is endemic to North America. It consists of three to five different genera and well over 200 species.
Scorpaeninae is a subfamily of ray-finned fish belonging to the family Scorpaenidae in the order Scorpaeniformes, it includes the scorpionfishes, the lionfishes and turkeyfishes. They bear venomous spines in the anal, dorsal and pelvic fins which can cause severe pain in envenomated humans. The subfamily is distributed in the tropical and temperate seas around the world.
Stichaeinae is a subfamily of marine ray-finned fishes, classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans.
Opisthocentrinae is a subfamily of marine ray-finned fishes, classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific Ocean.
