Beaufortia leveretti is a species of ray-finned fish in the genus Beaufortia .
It is native to fast-flowing streams of Red and Pearl River systems in China and Vietnam and to Hainan Island. It inhabits Japan, North Korea, South Korea and Vietnam and it has been introduced to Singapore. It is found in large rivers and streams, in shallow water over sandy bottom. Its maximum length is 12 cm (4.7 in) but it is usually much smaller. [2] In 2010, the status was changed from Data Deficient to Least Concern as this fish has a widespread range and no known threats.
It is fished but has low economic value. However, there are still unknown details such as population, threats and conservation measures.
The Pedder galaxias is an Australian freshwater fish. It is considered to be extinct in the wild since 2005 by the EPBC Act, and was originally found only in Lake Pedder in Tasmania.
The woundfin is a species of minnow endemic to the Virgin River of the southwestern United States. It is the only species in the monotypic genus Plagopterus.
The giant barb, Siamese giant carp, or simply Siamese carp, is the largest species of cyprinid in the world. These migratory fish are found only in the Mae Klong, Mekong, and Chao Phraya River basins in Indochina. Populations have declined drastically due to habitat loss and overfishing, and the giant barb is now considered critically endangered.
The Roanoke logperch is a small freshwater fish found in the Roanoke and Chowan drainages in Virginia and North Carolina in the United States. They inhabit low and moderate-gradient streams and rivers in warm, clear water in mostly unsilted gravel and rubble in runs, pools, and riffles. They are primarily insectivorous. This fish is a federally listed endangered species.
The Sandhills chub is a species of freshwater fish in the family Cyprinidae of order Cypriniformes. There are 4 species of Semotilus, 2 of which occur in South Carolina. This fish is found only in North Carolina and South Carolina. The Sandhills chub is predominately found in the Carolina Sandhills and some areas of Cape Fear, Pee Dee and Santee river drainages. It is characterized by its robust body, large head and a dark blotch or smudge on their dorsal fin. The Sandhills chub has fine scales, a pinkish body and can be up to 9.4 inches.
Bagarius rutilus is a species of sisorid catfish native to Laos, Vietnam and Yunnan in China where it is found in the Nam Sam, Nam Ma and Red River basins. This species grows to a length of 100 centimetres (39 in) SL.
Poropuntius laoensis is a species of ray-finned fish in the genus Poropuntius from the Mekong in Myanmar, Thailand, Laos and Vietnam. It is found in clear forested streams and is not found in large rivers. Id does not persist in impoundments and is not known to migrate. It feeds mainly on insect larvae.
Poropuntius normani is a species of ray-finned fish in the genus Poropuntius which occurs in hill streams and near waterfalls in the upland reaches of river drainages in eastern Thailand, Western Cambodia, the Kong River in Laos and in north central Vietnam. It is common and although threatened by habitat destruction through deforestation it is assessed as Least Concern by the IUCN. It is sometimes eaten but is not a specific target of fisheries and is sometimes turns up in the aquarium trade.
Schistura antennata is a species of ray-finned fish in the stone loach genus Schistura. It is found in very small, steep streams in forested mountains with rocky substrates and waterfalls, although it avoids riffles and waterfalls and is restricted to reaches with a moderate flow. It has only been recorded from the headwaters of the River Lam drainage in Ha Tinh Province in central Vietnam.
Schistura carbonaria is a species of ray-finned fish in the stone loach genus Schistura. It is found in central Vietnam in some coastal drainage systems, from the Ve River to the Qang Tri River, and the River Xe Kong, in the Xe Kong its range may extend into Laos. It can be found in medium-sized rivers and streams which have a strong current over a substrate of rocks and gravel.
Schistura namboensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It normally occurs in the rapids and riffles of medium-sized rivers and streams but it can also be found in reaches with a slow current and sandy substrate. This species appears to have some resistance to organic pollution and occurs in streams flowing through settlements, and is often the last fish species to remain in such streams. It is found in the coastal drainages in southern and central Vietnam and also in Laos in some rivers which rise there before flowing into Vietnam.
Beaufortia cyclica is a species of ray-finned fish in the genus Beaufortia.
Beaufortia pingi is a species of river loach. It occurs in China and Vietnam. It inhabits fast-flowing hill streams and grows to 5 cm (2.0 in) standard length.
Beaufortia polylepis is a species of river loach. It is endemic to the Nanpan River in Yunnan, China. It inhabits rocky streams and measures 3.9–4.8 cm (1.5–1.9 in) standard length.
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.
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.
Semilabeo notabilis is a species of cyprinid fish found in rivers and streams in China and Vietnam.
Elopichthys bambusa, the yellowcheek or kanyu, is a large cyprinid fish that is found in freshwater habitats in eastern Asia. It ranges from the Amur River in Russia, through China to the Red and Lam Rivers in Vietnam. It prefers relatively warm waters, entirely avoiding colder highlands. It is considered an important food fish where it occurs, reaching up to 2 m in total length and 52.2 kg (115 lb) in weight.
The red-backed paradise fish is a species of gourami endemic to streams in Vietnam. This species grows to a standard length of 6.5 cm (2.6 in), and it is sometimes seen in the aquarium trade.
The black paradisefish is a species of gourami endemic to Vietnam. It is an inhabitant of hill streams, lowland streams, and irrigation ditches in farmland. This species grows to a standard length of 5.8 cm (2.3 in). It is found in the Thu Bon River and Perfume River; its habitat is hill streams, along backwaters of large rivers and small stream and irrigation channels on farmland. Aside from possibly being used as an ornamental fish, nothing else is known about the species.
