Oxygaster pointoni is a freshwater ray-finned fish of the family Cyprinidae from the rivers of Indochina.
Oxygaster pointoni is a pelagic species which can be found near the surface of medium-sized rivers. [1] It probably has a similar diet to Oxygaster anomalura consisting of chironomids and small molluscs. [2]
Oxygaster pointoniis found in the Chao Phraya River and Mekong River in Thailand, Cambodia and Laos. [1]
O. pointoni is not normally encountered in fish markets and this means that it may be exploited at only by at a subsistence fishermen. It is unknown in aquaculture, so any fish harvested will be wild. It is threatened by the pollution and damming of the rivers it inhabits and the population of this fish has thought to have declined by 30% in the ten years up to 2009, which is why the IUCN classified it as "Vulnerable".

Herring are forage fish, mostly belonging to the family of Clupeidae.
The term carp is a generic common name for numerous species of freshwater fish from the family Cyprinidae, a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized quarries and are valued as both food and ornamental fish in many parts of the Old World, they are generally considered useless trash fish and invasive pests in many parts of Africa, Australia and most of the United States.
The Chao Phraya is the major river in Thailand, with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into the Gulf of Thailand.
Lake Tanganyika is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.
The Ganges shark is a critically endangered species of requiem shark found in the Ganges River and the Brahmaputra River of India and Bangladesh. It is often confused with the more common bull shark, which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark. The genus is currently considered to contain three recent species; genetic evidence has shown that both the Borneo river shark and Irrawaddy river shark should be regarded as synonyms of the Ganges shark, expanding the range of the species to Pakistan, Myanmar, Borneo, and Java. While the other members of the genus Glyphis occur in coastal marine waters as well as rivers, the Ganges shark is found only in fresh water, making it the world's only exclusively freshwater shark. The species remains poorly known and very rare.
The Olifants River is a river in the northwestern area of the Western Cape Province of South Africa. The upper and main catchment area of the Olifants river is around Ceres and the Cederberg mountains. The Clanwilliam and Bulshoek dams are located on the river and provide water for the towns and farms along the watercourse. The river is approximately 285 km long with a catchment area of 46,220 km2 and flows into the Atlantic Ocean at Papendorp, 250 km north of Cape Town.
The shovelnose sturgeon is the smallest species of freshwater sturgeon native to North America. It is often called hackleback, sand sturgeon, or switchtail. Switchtail refers to the long filament found on the upper lobe of the caudal fin. Shovelnose sturgeon are the most abundant sturgeon found in the Missouri River and Mississippi River systems, and were formerly a commercially fished sturgeon in the United States of America. In 2010, they were listed as threatened under the U.S. Endangered Species Act due to their resemblance to the endangered pallid sturgeon, with which shovelnose sturgeon are sympatric.
The wildlife of Liberia consists of the flora and fauna of the Republic of Liberia. This West African nation has a long Atlantic coastline and a range of habitat types, with a corresponding diversity of plants and animals. Liberia is considered a biodiversity hotspot and has more intact forests characteristic of the Upper Guinea Massif than do neighbouring countries. There are 2000 species of vascular plants, approximately 140 species of mammals, and over 600 species of birds.
The largemouth yellowfish or Vaal-Orange largemouth yellowfish is a ray-finned fish species in the family Cyprinidae. This large freshwater barb is found in southern Africa.
The Danube bleak or Caspian shemaya is a species of freshwater fish in the family Cyprinidae. It is found in Iran, Ukraine, Georgia, Armenia, Slovakia, Moldova, Greece, Czechia, Azerbaijan, Turkiye, Afghanistan, Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Switzerland, Germany, Hungary, Italy, Romania, Russia, Serbia, Slovenia, Turkmenistan, and Uzbekistan.
Dabry's sturgeon, also known as the Yangtze sturgeon, Chiangjiang sturgeon and river sturgeon, is a species of fish in the sturgeon family, Acipenseridae. It is endemic to China and today restricted to the Yangtze River basin, but was also recorded from the Yellow River basin in the past. It was a food fish of commercial importance. Its populations declined drastically, and since 1988, it was designated an endangered species on the Chinese Red List in Category I and commercial harvest was banned. It has been officially declared extinct in the wild by the IUCN as of July 21, 2022.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.
The Caspian lamprey, Caspiomyzon wagneri, is a species of lamprey native to the Caspian Sea, and a member of the Petromyzontidae family. This species is a non-parasitic lamprey that feeds on animal carcasses.
The chubbyhead barb is a species of freshwater ray-finned fish in the genus Enteromius. The fish is found throughout South Africa in a variety of aquatic environments. The species is notable for its two breeding seasons, which allows it to flourish despite a short lifespan.
The Modoc sucker is a rare species of freshwater fish native to northern California and southern Oregon. It grows to a length of about 7 in (18 cm) and becomes sexually mature at 4 in (10 cm). It feeds on algae, small invertebrates and detritus, and hides under stones, detritus and overhanging vegetation. It is found in only a few streams and is listed as an endangered species in California and the United States. Conservation measures have been put in place such as fencing the streams in which it lives from livestock. It was previously rated as "endangered" by the International Union for Conservation of Nature, but this rating has now been changed to "near threatened".
Oxygaster anomalura are medium-sized freshwater fishes in the family Cyprinidae, that can reach up to 200 mm SL(standard length), and are found near the surface in small- to medium-sized rivers in Southeast Asia, where they live off a diet of invertebrates.
The diamond mullet, is a species of mullet and is also known as the Ord River mullet. This species lives in both brackish or freshwater. Adult fish are found in estuaries, coastal waters and in some cases, ascending rivers into fresh water.
