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.
Lortet’s barbel is a species of ray-finned fish in the family Cyprinidae. It is only found in the lower course of Orontes River in Syria and Turkey. , the main lower cases of the river were poisoned and nearly dried in 1989 and changed the lake from being abundant to completely fishless. Aside from being extinct in Lake Amik, nothing else is known about the fish.
The Kessler's gudgeon is a European species of freshwater fish in the family Cyprinidae. It is found in the Danube and Vistula drainage basins, including parts of Poland, Austria, the Czech Republic, Ukraine, Bulgaria, Romania, Moldova, Hungary, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Slovakia, and Slovenia. It is a small fish of no economic or sporting importance. It was at one time classified as Gobio kessleri.
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 namiri, the Levantine loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is common and widespread in the drainage system of the Orontes in Turkey and Syria, as well as in coastal streams in Syria south of the border with Lebanon, where it can be found in springs, reservoirs, streams and rivers.
Schistura prashadi is a species of ray-finned fish, a stone loach, in the genus Schistura. Some authorities place it in the genus Physoschistura It is known from just three localities in the Chindwin River drainage in Manipur, India. It is a benthic species of hill streams, preferring well oxygenated, clear, flowing water.
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.
Oxynoemacheilus bergianus, the Kura sportive loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in Lake Urumiyeh and Namak Lake basins in Iran, in the southern Caspian basin from Kura east to the Sefid-Rud drainage. It can also be found in the headwaters of Tigris in Turkey, Iraq and in Karoun, Iran as well as those of the Euphrates in Turkey and possibly in Syria and Iraq. It lives in fast flowing streams and rivers with gravel and rocky substrates and does not tolerate impoundments, dam construction having been identified as a major potential threat to this species.
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.
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 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 is a genus of fish in the family Nemacheilidae found in Europe and Western Asia.
Osteochilus lini is a freshwater fish from Southeast Asia. It is found in the lower Mekong River basin, the Chao Phraya River basin, and some coastal drainages; it occurs in Laos, Vietnam, Cambodia, and Thailand. Its common name is dusky face carp.
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".
