The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, Afronemacheilus found in Africa. The family includes about 790 species.
The following are the described genera of the family: [2]
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.
Cobitidae, also known as the true loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families. The family includes about 260 described species. New species are being described regularly.
Balitoridae, the hillstream loaches or river loaches, is a family, of small fish from South, Southeast and East Asia. The family includes about 202 species. They are sometimes sold as "lizardfish" or "flossensaugers". Many of the species are popular for aquaria, species in the genus Sewellia are most commonly sold in the aquaria trade. They have a number of similarities with the Cobitidae, their sibling family of "loaches", such as multiple barbels around the mouth. They should not be confused with the loricariids, which look similar but are a family of catfish.
Barbatula is a genus of fish in the family Nemacheilidae native to Europe and Asia. They are found in streams, rivers and lakes, and the genus also includes Europe's only cavefish, which only was discovered in the Danube–Aachtopf system in Germany in 2015.
Nemacheilus is a genus of stone loaches native to Asia.
Schistura is a genus of fish in the stone loach family Nemacheilidae native to the streams and rivers of the southern and eastern Asia. Some of these species are troglobitic.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
Eudontomyzon vladykovi, or Vladykov's lamprey, is a species of lamprey in the family Petromyzontidae. It is found in Austria, Germany, The Czech Republic, Bulgaria, Romania, Serbia, and Montenegro.
Botiidae, the pointface loaches, is a family of cypriniform ray-finned fishes from South, Southeast, and East Asia. Until recently they were placed in the true loach family Cobitidae, until Maurice Kottelat revised the loaches and re-elevated this taxon to family rank in 2012. The family includes about 56 species.
Eudontomyzon stankokaramani, the Drin brook lamprey, is a non-predatory, freshwater resident species of lamprey found in the Drin river system of Albania and Kosovo and the basins of Lakes Ohrid and Shkodra.
The Kermanshah loach is a species of loach in the family Nemacheilidae endemic to Karkheh and Karun drainages in Iran. This species is the only member of its genus.
Loaches are ray-finned fish of the suborder Cobitoidei. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidei comprise about 107 genera divided among 9 families.
Homatula is a genus of stone loaches endemic to China.
Oxynoemacheilus is a genus of fish in the family Nemacheilidae found in Europe and Western Asia.
Paraschistura is a genus of stone loaches most of which occur in Central, South and Western Asia.
Physoschistura is a genus of fish in the family Nemacheilidae found mostly in Southeast Asia.
The Gastromyzontidae are a family of loaches native to China and Southeast Asia, where typically found in streams and rivers with a fast current. The family includes about 137 species in eighteen genera. This family was resurrected by M. Kottelat in his review and revision of the loaches in 2012. They are commonly called hillstream loaches.
Eonemachilus is a genus of ray-finned fish belonging to the family Nemacheilidae, the stone loaches. The fishes in this genus are found in China.
Traccatichthys is a genus of stone loaches from southern China and Vietnam.
Troglonectes is a genus of troglobitic fish in the family Nemacheilidae, native to caves of Asia. Fishbase and other authorities place these species in the genus Oreonectes.
