Nemacheilus is a genus of stone loaches native to Asia.
These are the currently recognized species in this genus: [1]
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.
Pangio is a genus of small Asian freshwater fish in the true loach family Cobitidae. In earlier taxonomic schemes it was known as Acanthophthalmus. The "kuhli loach" is well-known in the aquarium trade and commonly identified as P. kuhlii, but most individuals actually appear to be P. semicincta.
Rasbora is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.
Barbonymus is a ray-finned fish genus in the family Cyprinidae, containing some barb species. The genus was only established in 1999, with the tinfoil barb as type species; thus, these fish are sometimes collectively called tinfoils. The new genus was established in recognition of the fact that some large Asian "barbs", formerly rather indiscriminately lumped in Barbus, Barbodes and Puntius, form a distinct evolutionary lineage.
Hemibagrus is a genus of catfishes of the family Bagridae.
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.
Oxynoemacheilus seyhanensis, the Samanti loach, is a species of ray-finned fish in the family Nemacheilidae. It is found only in Turkey. Its natural habitat is rivers. It is threatened by habitat loss.
Lepidocephalichthys is a genus of ray-finned fish in the family Cobitidae.
Leptobotia is a genus of fish in the family Botiidae endemic to China.
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.
Oxynoemacheilus hamwii, the Orontes sportive loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in the headwaters of the Orontes River but is now restricted to three streams in the Turkish part of the drainage, two joining the lower Orontes in Turket and the third flowing into the Afrin River in Syria, and has been extirpated from Syria. It was described as being very common in the late 20th century, but it is sensitive to pollution and requires clear, flowing streams over mud or gravel. The drainage of the Orontes is heavily used by humans and lower rainfall in the region caused by climate change may exacerbate the threat to this species by increasing the amount of water taken from the streams by humans and by lowering the water table.
Schistura kodaguensis is a species of ray-finned fish, a stone loach, in the genus Schistura. This species has been recorded from a single stream with a swift current and gravel bottom in the Cauvery River system in Karnataka, India. The specific name is derived from Kodagu District where the type specimen was collected.
Acanthocobitis pavonacea, also known as the spearfin loach, is a species of ray-finned fish belonging to the family Nemacheilidae, the stone loaches. This species is found in the Brahmaputra River of Assam. This is one of two species in the genus Acanthocobitis, alongside the type species, A. longipinnis. A. longipennis was treated as synonym of this species but in 2021 Maurice Kottelat and Waikhom Vishwanath published a paper that argued that A. longipennis was a valid species and that it was one of two species ofloach in the genus Acanthocobitis, alongside A. pavonacea, with the other species being classified in the genus Paracanthocobitis. This species is the type species of the genus Acanthocobitis.
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.
Oxynoemacheilus is a genus of fish in the family Nemacheilidae found in Europe and Western Asia.
Physoschistura is a genus of fish in the family Nemacheilidae found mostly in Southeast Asia.
Sewellia is a genus of fish in the family Gastromyzontidae. They are commonly called hillstream loaches and are found in Laos and Vietnam. According to Roberts (1998) a possible defining characteristic of the genus Sewellia is their posterior pelvic valve is highly complex and different from other rheophilic loaches, their posterior pelvic valve involves the overlapping of the second to last ventrally exposed rays. Adapted to high velocity streams, Sewellia have depressed body shapes that are laterally expanded, thus increasing their hydrodynamical properties and allowing them to better stay attached to rocks in swift current. Sewellia also have paired fins with a single simple ray and numerous branched rays allowing them to grip rocks in swift current.
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.
Schistura callidora is a species of ray-finned fish in the stone loach genus Schistura. It was first found in the Myitnge River drainage, Irrawaddy basin in Myanmar. It is distinguished by possessing dark bars on its body, being much thinner in its anterior half; a high dorsal crest on the caudal peduncle; the number of dorsal-fin rays; and its lateral line which reaches behind the base of the anal fin.
