Capoeta, also known as scrapers, is a genus of fish in the family Cyprinidae found in Western Asia. The distribution extends from Turkey to the Levant, to Transcaucasia, Iraq, Turkmenistan, in Armenia,particularly in lake Sevan and northern Afghanistan. This genus is most closely related to Luciobarbus and in itself is divided into three morphologically, biogeographically and genetically distinct groups or clades: the Mesopotamian clade, the Anatolian-Iranian clade and the Aralo-Caspian clade.
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.
Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 140 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Garra typhlops, also known as the Iran cave barb is a species of ray-finned fish in the family Cyprinidae. It is endemic to caves in Iran. Like other cave-adapted fish, it is blind and lacks pigmentation.
Eidinemacheilus smithi, also known as the Zagroz blind loach, is a species of loach in the family Nemacheilidae. This cavefish is endemic to an aquifer in the Karun River drainage in the Zagros Mountains of Iran.
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.
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 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.
