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 insignis is a species of stone loach It is restricted to the Damascus basin in Syria and to the Jordan-Dead Sea basin in Syria, Israel and Jordan. Its natural habitat is rivers. It is threatened by the drying up of the rivers and streams in which it is found, caused by overuse, damming and less rainfall, as well as by pollution. In Syria it has been extirpated from the Barada and can now only be found in the upper reaches of the Awaj to the west of Damascus. It is a highly variable species and different populations can differ from their neighbouring populations that in the past they have been described as species or subspecies and this has led to a large number of synonyms for Oxynoemacheilus insignis.
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.
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 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 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 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 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 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 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.
