Schistura quasimodo | |
Schistura quasimodo is a species of stone loach (a ray-finned fish) in the genus Schistura . It is known from a single stream from the Nam Ngum drainage in Laos, a tributary of the Mekong. [1] It has a cylindrical body, sometimes with a conspicuous hump (the species epithet refers to Quasimodo, character in Victor Hugo's The Hunchback of Notre-Dame). The known material suggests a maximum standard length of about 48 mm (1.9 in). [2]
S. quasimodo has a very restricted distribution and may be threatened by pollution from mining activities, sedimentation from deforestation, and hydro-power development. [1]
Schistura is a genus of fish in the stone loach family Nemacheilidae native to the streams and rivers of the southern and eastern Asia. Some of these species are troglobitic.
Schistura aramis is a species of ray-finned fish in the stone loach genus Schistura from the Nam Nua catchment, a tributary of the Nam Ou in Laos, it may also possibly occur in Vietnam. The specific name comes from one of Alexandre Dumas' The Three Musketeers, Aramis as do that of two other Schistura species endemic to the Nam Ou basin, S. athos and S.porthos.
Schistura athos is a species of ray-finned fish in the stone loach genus Schistura, its specific name athos is from, Athos, one of the Three Musketeers by Alexandre Dumas, as do that of two other Schistura species endemic to the Nam Ou basin, S. aramis and S.porthos. It has only been recorded from the Nam Ou basin in Laos, as well as from a stretch of the Nam Noua, a tributary of the Nam Ou, in Vietnam. S. athos has been collected from rapids and stretches of the main river with stone substrates.
Schistura atra is a species of ray-finned fish in the stone loach genus Schistura. This species has only been recorded from the drainage systems of the Nam Theun and Nam Gnouang, tributaries of the Mekong, in Laos. It can be found in the parts of streams with deep water and fast currents where it lives among the rocks. The lower parts of the basins it occurs in have been impacted by damming and this species has probably been extirpated from these area but it continues to survive upstream of the reservoirs. The habitat of this fish is affected by deforestation, agriculture and gold mining as well as the dams.
Schistura bairdi is a species of ray-finned fish in the genus Schistura.
Schistura cataracta is a species of ray-finned fish in the stone loach genus Schistura. It occurs in the Nam Theun and Nam Gnouang, in the Mekong basin of Laos. It prefers stretches of rivers with fast current and a stony or rocky substrate, but it does occasionally occur over gravel or sandy substrates. It can also be found in reservoirs, albeit at low densities and dams are the biggest threat to this species.
Schistura clatrata is a species of ray-finned fish in the stone loach genus Schistura. It occurs in the Kong River basin in southern Laos. It was found in several sites within rapids with stony bottoms on two separate surveys in 1999 and 2009.
Schistura coruscans is a species of ray-finned fish in the stone loach genus Schistura from the Nam San drainage, a tributary of the Nam Ngum in Laos.
Schistura defectiva is a species of ray-finned fish in the stone loach genus Schistura from Laos.
Schistura ephelis is a species of ray-finned fish in the largest genus of stone loaches, Schistura. It is known only from the drainage basin of the Nam Ngum in Laos where it has been collected from among stones in riffles.
Schistura globiceps is a species of ray-finned fish in the genus Schistura. It has only been collected from a single stream in the upper Nam Tha watershed in Laos where it was found under stones in a fast flowing hill stream.
Schistura irregularis is a species of ray-finned fish in the stone loach genus Schistura, it is found in Laos.
Schistura khamtanhi is a species of ray-finned fish in the genus most speciose genus in the stone loach family, Schistura. It is found in the Kong River basin in Laos and in the main Mekong river in Cambodia and Laos where it is abundant, being an important quarry species for the fish traps at Kohne Falls. It inhabits rapids and Sony bottomed stretches of the main Mekong and its tributaries and it migrates past the Kohne Falls in January and February annually. It is the only member of the genus Schistura which is known to be migratory. The specific name honours Khamtanh Vatthanatham, a Fisheries Programme Officer of the Mekong River Commission who was very helpful to the Maurice Kottelat during his 1999 survey, in which this species was discovered.
Schistura kongphengi is a species of ray-finned fish, a stone loach, in the genus Schistura, the most specious of the genera of stone loaches. It occurs in the middle and upper parts of the Nam Gnouang drainage south to the drainage of the Xe Bang Hiang in Laos and Vietnam. It has been recorded from dstreams with moderate to fast currents over substrates of gravel and sands and among riffles and rapids. The specific name honours Kongpheng Bouakhamvongsa, an official with the Department of Livestock and Veterinary of the Ministry of Agriculture of the Lao People's Democratic Republic, for the help he gave to Maurice Kottelat with his field work in Laos.
Schistura latidens is a species of ray-finned fish, a stone loach, in the genus Schistura. It has been collected on one occasion from a single locality in 1997 from the Xe Banghiang watershed in Laos. It has not been searched for since. It was recorded in strong currents in riffles and rapids over a stony bed.
Schistura leukensis is a species of ray-finned fish, a stone loach in the genus Schistura. It has only been recorded from a single river, a tributary of the Mekong in Laos. This river has been affected by damming upstream of this species' main habitat and it is unknown how this has impacted the population. Other human activities such as deforestation, agriculture, siltation and pollution may have also had effects on this species.
Schistura novemradiata is a species of ray-finned fish, a stone loach, in the genus Schistura which has been recorded from a single locality in the upper Nam Tha watershed in Laos where it was found in a small stream over a substrate consisting of gravel and stone.
Schistura pertica is a species of ray-finned fish, a stone loach, in the genus Schistura. It has only been recorded once, in 1997, from a very small stream entering the Nam Ou River, downstream of the Muang Khoa River in northern Laos, it is expected to occur elsewhere in the Nam Ou drainage. It was observed in streams with a moderate to fast current, in riffles, over beds varying from gravel to stone
Schistura russa is a species of ray-finned fish, a stone loach, in the genus Schistura. It is known from only two locations in the Nam Tha drainage system in Laos where it is found in streams with a moderate to fast flow in riffles with pebble or stone stream beds.
Schistura sigillata is a species of ray-finned fish, a stone loach, in the genus Schistura from Laos.
