The sheepshead minnow or sheepshead pupfish is a species of ray-finned fish in the family Cyprinodontidae, the pupfishes. It is found in salt marsh and estuary environments and is native to the eastern coasts of North and Central America.
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.
The Ayumodoki or Kissing Loach is a species of ray-finned fish in the family Botiidae. It is found in lakes and streams on Honshu, the largest island of Japan. Spawning grounds for kissing loach are ditches and small reservoirs for rice cultivation of a river system located in Japan. The kissing loach migrates to flooded areas, including paddy field areas, for spawning in early summer and the spawning of this species is limited after the formation of flooded areas over terrestrial vegetation. These flooded areas are the result of water from mountain streams and irrigation ponds flooding once dry land which create creating man-made wetlands. As, adults, Parabotia curtus migrate from these flooded paddy fields to fast moving, muddy streams and rivers like the Yodo River.
The stone loach is a European species of fresh water ray-finned fish in the family Nemacheilidae. It is one of nineteen species in the genus Barbatula. Stone loaches live amongst the gravel and stones of fast flowing water where they can search for food. The most distinctive feature of this small fish is the presence of barbels around the bottom jaw, which they use to detect their invertebrate prey. The body is a mixture of brown, green and yellow.
Oxynoemacheilus galilaeus also known as the Galilean Stone Loach is a species of stone loach in the family Nemacheilidae native to Israel and Syria.
The loach goby, Rhyacichthys aspro, is a goby belonging to the family Rhyacichthyidae. It is not fished commercially.
Malapterurus beninensis is a species of electric catfish native to the African nations of Angola, Benin, Cameroon, the Democratic Republic of the Congo, the Republic of the Congo, Equatorial Guinea, Gabon, Ghana, Nigeria and Togo. This species grows to a length of 22 cm (9 in) SL. Its habitat is lowland marshes, rivers, and lakes.
Synodontis contractus, the bugeye squeaker, is a species of upside-down catfish native to the Congo Basin of the Democratic Republic of the Congo and the Republic of the Congo. This species can be found in the aquarium trade.
Synodontis pardalis is a species of upside-down catfish that is endemic to Cameroon where it occurs in the Dja River drainage. It was first described by British-Belgian zoologist George Albert Boulenger in 1908, from specimens collected in the Dja River in southern Cameroon. The species name pardalis is derived from the Greek word pardalis, which means "leopard", which refers to the spotted pattern on the fish.
Synodontis robbianus, known as the russet synodontis, is a species of upside-down catfish that is native to Nigeria where it is found in the Cross and lower Niger Rivers. It was first described by John Alexander Smith in 1875, from specimens collected in the Calabar River, Nigeria. The species name robbianus is named after Rev. Alexander Robb, a Scottish missionary, who collected the original species samples.
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.
The Java barb, more commonly known as silver barb in aquaculture, is a species of ray-finned fish in the genus Barbonymus.
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 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 phoxinoides, the Iznik loach, is a species of ray-finned fish in the genus Oxynoemacheilus. The species is endemic to a single small stream, less than 5 km in length in the drainage of Lake Iznik in north-western Anatolia, Turkey. The species is abundant in its restricted habitat but the population seems to be declining with abstraction of water from the stream for irrigation thought to be the main threat but as climate changed reduces the rainfall in the region the likelihood of droughts is increased.
Noturus flavus, the stonecat, is a North American freshwater catfish of the family Ictaluridae. The common name is due to its habit of hiding near or under stones in fast-moving 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.
Schistura scripta, is a species of ray-finned fish in the genus Schistura, newly identified from Sri Lanka. It is the third species of Schistura stone loach described from Sri Lanka, the other being the widely distributed native species Schistura notostigma and endemic Schistura madhavai.
