Oreichthys duospilus is a small cyprinid fish endemic to the Sharavati River basin in Karnataka. [1]
Actinopterygii, members of which are known as ray-finned fishes, is a clade of the bony fishes.
Aquaculture, also known as aquafarming, is the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.
Osteichthyes, popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue, as opposed to cartilage. The vast majority of fish are members of Osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, and over 435 families and 28,000 species. It is the largest class of vertebrates in existence today. The group Osteichthyes is divided into the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). The oldest known fossils of bony fish are about 420 million years old, which are also transitional fossils, showing a tooth pattern that is in between the tooth rows of sharks and bony fishes.
Perciformes, also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". This group comprises over 10,000 species found in almost all aquatic ecosystems.
The United States Fish and Wildlife Service is an agency of the US federal government within the US Department of the Interior dedicated to the management of fish, wildlife, and natural habitats. The mission of the agency is "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people."
Fish farming or pisciculture involves raising fish commercially in tanks or enclosures such as fish ponds, usually for food. It is the principal form of aquaculture, while other methods may fall under mariculture. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, tilapia, salmon, and catfish.
A fishery is the enterprise of raising or harvesting fish and other aquatic life. Commercial fisheries include wild fisheries and fish farms, both in fresh water and the oceans. About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem. Recreational fishing is popular in many locations, particularly North America, Europe, New Zealand, and Australia.
Teleostei, members of which are known as teleosts, is by far the largest infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all extant species of fish. Teleosts are arranged into about 40 orders and 448 families. Over 26,000 species have been described. Teleosts range from giant oarfish measuring 7.6 m (25 ft) or more, and ocean sunfish weighing over 2 t, to the minute male anglerfish Photocorynus spiniceps, just 6.2 mm (0.24 in) long. Including not only torpedo-shaped fish built for speed, teleosts can be flattened vertically or horizontally, be elongated cylinders or take specialised shapes as in anglerfish and seahorses. Teleosts dominate the seas from pole to pole and inhabit the ocean depths, estuaries, rivers, lakes and even swamps.
Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups.
Fusigobius is a genus of coral reef inhabiting gobies found throughout the Indian and western Pacific Oceans.
The California Department of Fish and Wildlife (CDFW), formerly known as the California Department of Fish and Game (CDFG), is a state agency under the California Natural Resources Agency. The Department of Fish and Wildlife manages and protects the state's fish, wildlife, wildflowers, trees, mushrooms, algae (kelp) and native habitats (ecosystems). The Department is responsible for regulatory enforcement and management of related recreational, commercial, scientific, and educational uses. The Department also prevent illegal poaching.
Rhinogobius is a genus of primarily freshwater gobies native to tropical and temperate parts of eastern Asia. Most are small, streamlined in shape, and often sexually dimorphic. Few are of commercial importance, but R. duospilus is fairly widely traded as an aquarium fish.
Oreichthys cosuatis is a small cyprinid fish found in India and Bangladesh.In India it is found along the ganga and brahmaputra river drainage in the states of West bengal and odisha It is also reported from Thailand and Myanmar.
Oreichthys crenuchoides is a small cyprinid found in Assam, India. It is imported for the aquarium trade under the name neon highfin barb or high-fin variable barb. It is an atypical Oreichthys in that the face is more rounded than in O. cosuatis and other Oreichthys species.
Oreichthys is a genus of tropical barbs found in Thailand, India, Bangladesh, Myanmar (Burma), northern Malay Peninsula, and the Mekong basin in Laos. They are found in ditches, ponds, streams and canals. The genus Oreichthys was originally established to receive little fish collected in a small brook on Kao Sabap, an extensive mountain range near Chantaban, Thailand.
Rhinogobius duospilus is a species of goby native to China and Vietnam where they can be found in fresh or brackish waters. This species can reach a length of 4.5 centimetres (1.8 in) TL. In their natural environment these fish consume larvae or other similar creatures, but they can be fed brine shrimp or blood worms.
Oreichthys parvus is a small cyprinid fish found in southeastern Thailand, northern Malay Peninsula and Mekong basin in Laos and Thailand.
Oreichthys coorgensis is a small cyprinid fish found in Western Ghats, India. It is endemic to the Cauvery River in Karnataka.
Oreichthys andrewi is a small cyprinid fish endemic to the Dibru River in Assam.
