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.
Cobitis is a genus of small freshwater fish in the family Cobitidae from temperate and subtropical Eurasia. It contains the "typical spiny loaches", including the well-known spined loach of Europe. Similar spiny loaches, occurring generally south of the range of Cobitis, are nowadays separated in Sabanejewia.
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 samanticus, the Kizilirmak sportive loach, is a species of ray-finned fish in the genus Oxynoemacheilus. It is found in streams and rivers with a fast current over gravel substrate and is endemic to eastern Anatolia, Turkey where it is found in the Kizilirmak system which drains into the Black Sea, as well as the headwaters of the Euphrates.
Oxynoemacheilus seyhanicola is a species of ray-finned fish in the genus Oxynoemacheilus. It is endemic to an estimated 60 km of the lower Seyhan river near Adana in Turkey where it can be found in moderately fast currents with a gravel substrate. It is threatened by dams, water extraction and climate change.
Oxynoemacheilus mediterraneus, the Pamphylian loach, is a species of Cypriniformes fish in the genus Oxynoemacheilus. This species is found in the Lake Eğirdir drainage of central Anatolia and in the Aksu and Küpü rivers draining to the Gulf of Antalya. It is widespread and normally abundant in streams with fast flowing currents to almost standing waters. It is, however, locally decreasing due to dam constructions and is also threatened by pollution and water abstraction, as well as by reduced regional rainfall due to climate change.
Oxynoemacheilus paucilepis, the Mancilik dwarf loach is a species of ray-finned fish in the genus Oxynoemacheilus. This species is endemic to the Mancilik, Cetinkaya and Kalkam streams I the headwaters of the Euphrates in eastern Anatolia, Turkey. It may have been extirpated from the Mancilik after none were found at the type locality in 2008 but it was found to be abundant at another locality on the same stream in 2009. Its preferred habitat is small streams with gravel beds and a moderately fast current.
Oxynoemacheilus phoxinoides, the Iznik loach, is a species of ray-finned fish in the genus Oxynoemacheilus. The species is endemic to a single small stream, less than 5 km in length in the drainage of Lake Iznik in north-western Anatolia, Turkey. The species is abundant in its restricted habitat but the population seems to be declining with abstraction of water from the stream for irrigation thought to be the main threat but as climate changed reduces the rainfall in the region the likelihood of droughts is increased.
Oxynoemacheilus tigris, the Tigris loach or Halap loach, is a species of stone loach from the genus Oxynoemacheilus. This critically endangered species is endemic to the Queiq River in Turkey where it occurs ins a short stretch of stream between two reservoirs. It formerly occurred in Syria but it has been local extinction from the Syrian portion of the Queiq. This species is threatened by water abstraction and the increased frequency of droughts caused by climate change, most of the Queiq has already been desiccated. It is, however, abundant in the area it is known from where it can be found in reaches of gravel or mud substrate with moderately fast flowing to near standing water.
Oxynoemacheilus longipinnis is a species of loach in the family Nemacheilidae endemic to the Meymeh River, formerly a part of the Tigris-Euphrates system in Iran. Fishbase lists it as the only species in the monotypic genus Ilamnemacheilus.
Oxynoemacheilus is a genus of fish in the family Nemacheilidae found in Europe and Western Asia.
Paracobitis is a genus of Asian stone loaches.
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.
Oxynoemacheilus anatolicus, the Burdur loach, is a species of stone loach in the genus Oxynoemacheilus. It has been only recorded from three spring fed streams which used to drain into Lake Burdur in south-western Anatolia, Turkey. Its habitat is streams with a slow current flowing through dense aquatic vegetation over a bed of sand, mud or gravel. It is still found in the three streams and in one it is said to be abundant but it is still threatened by water extraction, pollution and dam construction. In addition, waterbodies in the area it is found in are drying out because of climate change and unsustainable extraction of water for human use.
Oxynoemacheilus chomanicus is a species of stone loach for the genus Oxynoemacheilus. It is found in Iranian Kurdistan.
Oxynoemacheilus eregliensis is a species of stone loach from the streams and springs with gravel, sand or mud substrate and slowly flowing water in the area of the Lake Tuz basin in central Anatolia in Turkey.
Oxynoemacheilus karunensis is a species of stone loach which is endemic to Iran. It was first described in 2016.
Oxynoemacheilus kiabii is a species of stone loach from the genus Oxynoemacheilus which is endemic to the Karkheh River drainage in Iran. The authors Kiavash Golzarianpour, Asghar Abdoli and Jörg Freyhof gave the specific name kiabii in honour of the Iranian conservationist Bahram H. Kiabi to show their appreciation for his work in conserving Iran's vertebrate fauna, especially the fish.
Oxynoemacheilus kurdistanicus is a species of stone loach which is endemic to the Choman River in Iranian Kurdistan. They grow up to 6.9 cm or 2.71 inches in length. They are vertebrates with soft rays. This type of species are harmless to humans.
Oxynoemacheilus tongiorgii is a species of stone loach from the genus Oxynoemacheilus. It is found in the Kul River basin in Iran. It has only been recorded once.
