Oxygaster pointoni is a freshwater ray-finned fish of the family Xenocyprididae 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". [1]
Herring are various species of forage fish, belonging to the order Clupeiformes.
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 considered trash fish and invasive pests in many parts of Africa, Australia and most of the United States.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
The Chao Phraya River 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-largest freshwater lake by volume and the second deepest, in both 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, Burundi, and Zambia—with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. It drains via the Lukuga River into the Congo River system, which ultimately discharges at Banana, Democratic Republic of the Congo 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. 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. It 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.
Labeobarbus johnstonii is a species of cyprinid fish. It has long been placed in Barbus, the "wastebin genus" for barbs, by default, and this is still being done by the IUCN. However, the species is increasingly being restored to related yellowfish genus Labeobarbus which seems a much more appropriate placement. It is presumably hexaploid like the other yellowfish. The supposed subspecies latirostris of its relative L. intermedius is actually misidentified L. johnstonii.
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, Changjiang 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.
Ochetobius is a monospecific genus of freshwater ray-finned fish belonging to the family Xenocyprididae, the East Asian minnows or sharpbellies. The only species in the genus is Ochetobius elongatus, a fish found in eastern Asia.
Oxygaster is a genus of freshwater ray-finned fish belonging to the family Xenocyprididae, the East Asian minnows or sharpbellies. The species in this genus are found in Southeast Asia.
Oxygaster anomalura are medium-sized freshwater fishes in the family Xenocyprididae, 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.
