Oxynoemacheilus bureschi, the Struma stone loach, is a species of ray-finned fish in the stone loach family (Nemacheilidae). It is found in the Struma, Vardar and Nestos river basins Bulgaria, Greece, North Macedonia, and Serbia Its natural habitat is rivers, preferring larger streams with fast currents, especially in the middle. It cannot survive where the rivers have been canalised and it is threatened by habitat loss. The specific name honours the Bulgarian ichthyologist Ivan Buresh, who was able to influence the Bulgarian monarch Boris III to allow Drensky to collect specimens in Bulgaria.

Oxynoemacheilus ceyhanensis, the Elbistan loach, is a species of Cypriniformes fish in the stone loach genus Oxynoemacheilus. It is found in moderately fast flowing streams with gravel or rocky beds and is known only from the Elbistan in upper drainage of the Ceyhan River in south eastern Turkey.
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 argyrogramma, the two-spot loach is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in the drainage of the Queiq River in Syria and Turkey, and the upper Euphrates drainage in Turkey and possibly in this drainage in Syria and Iraq. It has almost been extirpated from the Queiq as this river has virtually dried out but it remains abundant in the Euphrates. This species can be found in a wide range of habitats as long as there is a moderately fast current from small upland streams to banks of large rivers. It can also occur in stagnant water bodies such as reservoirs. It is threatened by water abstraction, lowering rainfall due to climate change and the construction of dams. The economic development of the area where this species occurs exacerbates these threats. Freyhof and Özuluǧ published a paper in 2017 that argued that Oxynoemacheilus euphraticus was a valid species and not a synonym of O. argyrogramma.
Oxynoemacheilus frenatus, the banded Tigris loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is widespread in the upper drainage basin of the Tigris in Turkey, Syria and Iraq where it can be locally very common. It can be found in habitats varying from streams with a moderately fast current to near standing waters in springs, streams and rivers which have beds of gravel or mud.
Oxynoemacheilus germencicus, the Carian loach, is a species of Cypriniformes fish in the genus Oxynoemacheilus. It is known only from the Büyük Menderes River and lower Gediz River in western Anatolia, it probably also occurred in the Kücük Menderes, a river which sits between the Büyük Menderes and Gediz, and has been extirpated from that river by pollution and abstraction. It remains widespread and locally abundant in the other two rivers but the populations have declined and the species is threatened by climate change reducing rainfall in the area and human activities such as damming and water abstraction as well as pollution>
Oxynoemacheilus kosswigi, the Paphlagonian loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in the Kizilirmak and Yeşilırmak drainages in northern Anatolia, Turkey. It lives in waters which vary from those with a moderately fast flow to almost still waters and prefers muddy or gravel substrates, It remains abundant and widespread within the two drainage systems in which it occurs but it is suspected that a number f populations may have declined or been made locally extinct by the increasing construction of small hydro-electric dams.
Oxynoemacheilus panthera, the tiger loach or the Damascus loach, is a species of ray-finned fish in the genus Oxynoemacheilus. It occurs in only two streams, the Nahr Baradá and Nahr al-A‘waj in the Damascus basin in Syria. It is thought that over 90% of the populations of this species of stone loach have been lost due to water abstraction and the drying up of its native watercourses, exacerbated by lower 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 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.
Angora loach is a species of ray-finned fish in the family Nemacheilidae. It is found in Israel, Jordan, Lebanon, Syria, and Turkey. It is found in Sea of Marmara and Black Sea from Simav east to Kızılırmak River drainages and drainages of Ilgin, Lake Akşehir and Lake Eber.
Oxynoemacheilus is a genus of fish in the family Nemacheilidae found in Europe and Western Asia.
Oxynoemacheilus atili, the Lake Beyşehir loach, is a species of stone loach from the genus Oxynoemacheilus. It is endemic to Turkey being found only in the drainage basin of Lake Beyşehir in Central Anatolia, where it occurs in all the streams and in the Manavgat drainage in Mediterranean basin.
Oxynoemacheilus cyri, the Göle loach or banded Kura loach, is a species of stone loach from the genus Oxynoemacheilus. It is endemic to the Kura drainage in northern Turkey where it is currently locally abundant. This species occurs in high mountain streams with fast flowing currents. The specific name derives from the classical name for the Kura, "Cyrus".
Oxynoemacheilus kaynaki, the medil loach, is a species of stome loach which is found in the Göksu, a right hand tributary of the Euphrates in southeast Anatolia, Turkey.

It is found in the western drainage basin of the Caspian Sea in eastern Europe in the upper mountain streams of the drainage systems of the Kuma, Terek, Sulak, Shura-ozen and Samur where it is abundant. The countries in which it occurs are Azerbaijan, Georgia and Russia.
