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 evreni is a species of Cypriniformes fish in the genus Oxynoemacheilus. It is widespread and locally abundant within the Ceyhan drainage where it can be found in streams and rivers which have a gravel substrate in a relatively fast to very fast current. It may have undergone a slight reduction in population due to the construction of dams but it is able to tolerate some habitats which have been altered by humans.
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.
The arrow loach is a species of ray-finned fish in the genus Nemacheilus.
Oxynoemacheilus theophilii is a species of stone loach native to Turkey and the island of Lesbos in Greece. This species occurs in streams and reaches a length of 6.6 centimetres (2.6 in) SL. It is found in the Büyük Menderes River and other streams in western Anatolia, Turkey, and the Evergetoulas Stream on the island of Lesbos, Greece. It can be found in the upper reaches of streams with clear, cold, flowing water where it hides among the stones of the stream bed. The stomach contents of a single female were found to consist of aquatic insect larvae. Water abstraction and the increased droughts caused by climate change are the main threats.
The Kura loach, also known as the Caspian sportive loach, is an Asian species of freshwater fish, occurring in the drainage basin of the Kura in Armenia, Azerbaijan, Turkey and Iran. It prefers fast to very fast flowing streams and rivers which have a gravel or rocky substrate and is most frequently recorded among riffles and rapids in the middle of stream. It is widespread and locally abundant but populations have been lost due to the construction of dams for hydroelectric power and for abstraction. The specific bane honours the German naturalist Johann Friedrich von Brandt (1802-1879), who provided Karl Kessler with most of the specimens he used to describe this species.
Claea dabryi is a species of stone loach endemic to the Jinshajiang river basin in China. Commonly known as 戴氏南鰍, which translates as Dai's southern loach.

Turcinoemacheilus kosswigi is a species of stone loach which is endemic to the Tigris-Euphrates Basin where it can be found in the stretches of rivers, eve small streams, with faster currents and it often occurs on riffles and rapids. The specific name honours the zoologist and geneticist Curt Kosswig (1903-1982), who collected the type specimen of this species among others he collected in Turkey.
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 banarescui, the Paphlagonian sportive loach, is a species of stone loach from the genus Oxynoemacheilus. It is endemic to the Filyos River in northern Turkey where it is currently widespread and abundant. However, the population appears to be declining and the causes of this are thought to be increased development of the drainage basin and the construction of new dams. This species prefers fast flowing streams with rocky or gravel bottoms and cannot survive in reservoirs, although the dams on the Fliyos are for flood control and not to create reservoirs and their impact on this species is unknown. The specific name honours Petre Mihai Bănărescu (1921-2009), a Romanian ichthyologist.
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.
