Sperata is a genus of bagrid catfishes.
There are currently six recognized species in this genus: [1] [2]
Species of Sperata are found in southern Asia from Afghanistan to Thailand where they are found in a wide variety of water bodies.
At least two of the Sperata species (S. aor & S. seenghala) are sport fish as well as being important food fish.
Catfish are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores, and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal, but others are crepuscular or diurnal.
AOR may refer to:
Callichthyidae is a family of catfishes, called armored catfishes due to the two rows of bony plates along the lengths of their bodies. It contains some of the most popular freshwater aquarium fish, such as many species in the genus Corydoras.
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 7,000,000 km2 (2,700,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana.
The Ictaluridae, sometimes called ictalurids, are a family of catfish native to North America, where they are an important food source and sometimes fished for sport. The family includes about 51 species, some commonly known as bullheads, madtoms, channel catfish, and blue catfish.
The Pimelodidae, commonly known as the long-whiskered catfishes, are a family of catfishes.
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species.
Wallago attu, the boal or helicopter catfish is a freshwater catfish of the family Siluridae, native to South and Southeast Asia. W. attu is found in large rivers and lakes in two geographically disconnected regions, with one population living over much of the Indian Subcontinent and the other in parts of Southeast Asia. This species can reach a length up to 1.1 m.
Pterygoplichthys, sometimes collectively known as janitor fish, is a genus of South American armored catfishes. These fish are commonly known as sailfin armoured catfish or sailfin plecs, especially in the aquarium trade.
Rineloricaria is a genus of freshwater tropical catfish belonging to the family Loricariidae. They are commonly called whiptail catfish because of the long filament that grows out of the tip of the caudal fin that is characteristic of the genus. With the exception of R. altipinnis from Panama, they are native to the rivers of northern and central South America. Some species are regularly seen in the aquarium trade.
Chaca is the only genus in the catfish family Chacidae. These fish are commonly known as squarehead catfishes, frogmouth catfishes, or angler catfishes. These unusual fish have a sedentary lifestyle and spend much of their time motionless.
Sorubim is a small genus of long-whiskered catfish native to tropical South America. A number of characteristics allows the differentiation of each species in the genus. Sorubim species are important food fish in South America and are highly significant to fisheries of some areas; however, harvests of these fish are not identified as much as other, more popular food fishes such as Colossoma, Arapaima, and Brachyplatystoma. Some species of this family are popular aquarium fish.
Brachyplatystoma is a genus of catfish from the family Pimelodidae. As the occasionally used common name goliath catfishes indicates, this genus includes some of the largest species of catfish, including the piraíba, B. filamentosum, which reaches up to 3.6 metres (12 ft) in length; though the other species don't reach this length. Brachyplatystoma are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. Many species are migratory. These fish are important as food fish and, to some extent, aquarium fish.
Heteropneustes is a genus of catfishes, the airsac catfishes, native to Asia. This genus is monotypic in the family Heteropneustidae.
Sperata acicularis is a species of bagrid catfish endemic to Myanmar where it is found in the Irrawaddy, Bago, and Great Tenasserim River systems of Myanmar.
Sperata aor, the long-whiskered catfish, is a species of catfish of the family Bagridae found in southern Asia in the nations of India, Pakistan, Nepal, Bangladesh and Myanmar. It grows to a length of 180 centimetres (71 in) and is commercially fished for human consumption. It is also a popular gamefish.
Sperata aorella is a species of bagrid catfish that occurs in the Ganges River in India and Bangladesh.
Sperata seenghala, the Giant river-catfish, is a species of bagrid catfish. It is known locally as Guizza, Guizza ayer, Auri, Ari, Pogal, Singhara and Seenghala, among other names. It is found in southern Asia in the countries of Afghanistan, Pakistan, India, Nepal and Bangladesh with reports of occurrence in Myanmar, Thailand and Yunnan, China. It can reach a length of 150 cm, though lengths up to 40 cm are more usual. It is commercially fished for human consumption as well as being a popular gamefish with a reputation for being a good fighter when hooked. It is carnivorous in diet. It can be distinguished from other Sperata species by its spatulate, blunt snout, relatively short barbels and mouth that is only 1/3 as wide as the head is long.
Vikramshila Gangetic Dolphin Sanctuary is located in Bhagalpur District of Bihar, India. The sanctuary is a 60 kilometers stretch of the Ganges River from Sultanganj to Kahalgaon in Bhagalpur district. notified as Vikramshila Gangetic Dolphin Sanctuary in 1991, it is the protected area for the endangered Gangetic dolphins in Asia. Once found in abundance, only a few hundred remain, of which half are found here.
