The Nam Theun 2 Hydropower Project, or simply NT2, is a hydroelectric dam located on the Nam Theun River in Laos. Commercial operation of the plant began in April 2010. The scheme diverts water from the Nam Theun, a tributary of the Mekong River, to the Xe Bang Fai River, enabling a generation capacity of 1,075 MW, from a 350 m (1,148 ft) difference in elevation between the reservoir and the power station.
Rhodeus laoensis is a tropical freshwater fish belonging to the Acheilognathinae subfamily of the Cyprinidae family. It originates in Nam Theun River in the Mekong Delta in Laos. The fish reaches a length up to 4.7 cm (1.9 in). When spawning, the females deposit their eggs inside bivalves, where they hatch and the young remain until they can swim.
Tylognathus is an invalid genus of ray-finned fishes in the family Cyprinidae. It was established by Heckel in 1843 without a type species. Varicorhinus diplostomus, described by Heckel in 1838 and erroneously redescribed by the same author in 1844 as T. valenciennesii, was later designated the type species. Today this fish is placed in the genus Bangana.
The Nakai–Nam Theun National Biodiversity Conservation Area (NBCA), located in Laos, comprises one of the most pristine wildernesses remaining in Southeast Asia. Nakai–Nam Theun NBCA covers approximately 3,445 km2 of the Annamite mountains and the adjacent Nakai Plateau in the provinces of Khammouane and Bolikhamxay. The reserve headquarters is located in Nakai, the capital of Nakai District.
Systomus jacobusboehlkei is a species of cyprinid fish native to the lower Mekong and Chao Phraya Basins of Cambodia, Vietnam, Laos, and Thailand. It inhabits marshlands and floodplains, swamps, and small, slow-flowing tributaries. It is present in local food fisheries, along with other small species. This species can reach a length of 12 centimetres (4.7 in) SL.
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 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 nudidorsum is a species of ray-finned fish, a stone loach, in the genus Schistura. This species has only been recorded from the drainage basins of the Nam Theun and Nam Gnouang, tributaries of the Mekong in Laos. It occurs in streams with a moderate to fast current and a substrate which varies from gravel to stone, in riffles. It is threatened by the construction of dams, as well as logging, deforestation, agriculture and gold mining.
Schistura tubulinaris is a species of ray-finned fish in the genus Schistura, itis endemic to the Nam Theun of the Mekong basin in Laos.
Nemacheilus arenicolus is a species of ray-finned fish in the genus Nemacheilus which is found only in the Nam Theun and Nam Gnouang rivers in Laos.
Gyrinocheilus aymonieri is a freshwater fish native to large parts of Southeast Asia. It is of interest as a local food source and for the aquarium trade. Its common names include honey sucker, sucking loach, Chinese algae eater, and Siamese algae eater; the FAO-endorsed common name is Siamese algae eater.
Bangana is a genus of fish in the family Cyprinidae, the carps and minnows. It is distributed across much of southern and eastern Asia. Species live mainly in the flowing waters of tropical and subtropical rivers.
Datnioides microlepis, also known as the Indonesian tiger datnoid, Indo datmoid, Indonesian tigerfish, or finescale tigerfish, is a species of freshwater fish endemic to the Malay Peninsula and Indonesia. Previous records from the Chao Phraya and Mekong rivers is due to confusion with the D. pulcher, which was included in D. microlepis until 1998. It reaches up to 45 cm in length. This fish is commonly seen in the aquarium trade, and often is seen when juvenile about 3–4 in (8–10 cm) long.
Scaphiodonichthys acanthopterus is a freshwater fish of the family Cyprinidae. It is found in clear, fast-moving streams and tributaries of the Mekong, Nam Xam, Da and Chao Phraya river basins in Indochina. S. acanthopterus is most commonly found in waterways with a rocky bottom and under complete tree cover.
Vinalabeo tonkinensis is a species of fish in the family Cyprinidae native to the Red River basin in China and Vietnam. This species is the only member of its genus.
Paraspinibarbus macracanthus, the pocket-like lip barbel, is a species of freshwater ray-finned fish from the carp and minnow family, the Cyprinidae. It occurs in the Nam Xam and Nam Ma river basins in Laos, the Red River basin in Vietnam and Yunnan, as well as in most of the coastal drainage basins of northern Vietnam.
Pseudohemiculter dispar is a species of freshwater ray-finned fish from the family Cyprinidae, the carps and minnows from south east Asia. It occurs in the Mekong and Nam Ma basins in Laos, central and northern Vietnam, and southern China.
