Discocheilus multilepis is a fish species in the genus Discocheilus from China. [1]
Discocheilus is a genus of cyprinid fishes endemic to China. This genus contains two recognized species.
Actinopterygii, or the ray-finned fishes, constitute a class or subclass 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.
Jonah or Jonas is the name given in the Hebrew Bible to a prophet of the northern kingdom of Israel in about the 8th century BCE. He is the eponymous central figure of the Book of Jonah, in which he is called upon by God to travel to Nineveh and warn its residents of impending divine wrath. Instead, Jonah boards a ship to Tarshish. Caught in a storm, he orders the ship's crew to cast him overboard, whereupon he is swallowed by a giant fish. Three days later, after Jonah agrees to go to Nineveh, the fish vomits him out onto the shore. Jonah successfully convinces the entire city of Nineveh to repent, but waits outside the city in expectation of its destruction. God shields Jonah from the sun with a plant, but later sends a worm to cause it to wither. When Jonah complains of the bitter heat, God rebukes him.
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.
Ichthyology, also known as fish science, is the branch of zoology devoted to the study of fish. This includes bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). While a large number of species have been discovered, around 250 new species are officially described each year. According to FishBase, 33,400 species of fish had been described as of October 2016.
Fish sauce is a liquid condiment made from fish or krill that have been coated in salt and fermented for up to two years. It is used as a staple seasoning in the cuisines of Southeast and East Asia, particularly Indonesian, Burmese, Cambodian, Filipino, Thai, Lao, Malaysia, and Vietnamese.
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.
The teleosts or Teleostei are by far the largest infraclass in the class Actinopterygii, the ray-finned fishes, and make up 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.
Actinopteri is the sister group of Cladistia. Dating back to the Permian period, the Actinopteri comprise the Chondrostei and the Neopterygii. In other words, the Actinopteri include all extant Actinopterygians, minus the Polypteridae (bichirs). The Actinopteri includes:
Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish in time, resulting in those species either becoming depleted or very underpopulated in that given area. Overfishing has spread all over the globe and has been present for centuries.
The fishing industry includes any industry or activity concerned with taking, culturing, processing, preserving, storing, transporting, marketing or selling fish or fish products. It is defined by the Food and Agriculture Organization as including recreational, subsistence and commercial fishing, and the harvesting, processing, and marketing sectors. The commercial activity is aimed at the delivery of fish and other seafood products for human consumption or as input factors in other industrial processes. Directly or indirectly, the livelihood of over 500 million people in developing countries depends on fisheries and aquaculture.
A fishfinder or sounder (Australia) is an instrument used to locate fish underwater by detecting reflected pulses of sound energy, as in sonar. A modern fishfinder displays measurements of reflected sound on a graphical display, allowing an operator to interpret information to locate schools of fish, underwater debris, and the bottom of body of water. Fishfinder instruments are used both by sport and commercial fishermen. Modern electronics allows a high degree of integration between the fishfinder system, marine radar, compass and GPS navigation systems.
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. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods. Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology, unless it is used in the cladistic sense, including tetrapods. The traditional term pisces is considered a typological, but not a phylogenetic classification.
Acanthopterygii is a superorder of bony fishes in the class Actinopterygii. Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole.
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, plant and native habitats. It is responsible for related recreational, commercial, scientific, and educational uses. It also works to prevent illegal poaching.
Chaunax is a genus of bony fish in the sea toad family Chaunacidae. They are found in tropical and subtropical oceans around the world and most species are found a depths between 180 and 1,100 m, but C. endeavouri occurs as shallow as 50 m (160 ft) and C. fimbriatus as deep as 1,985 m (6,512 ft). Depending on the exact species involved, they reach a total length of 11–40 cm (4.3–15.7 in).
Pescetarianism is the practice of following a diet that includes fish and other seafood, but not the flesh of other animals. Those on pescetarian or pollotarian diets may define "meat" only as mammalian flesh and may identify as vegetarians. Most pescetarians are lacto-ovo vegetarians with the addition of fish and shellfish, described as "fish but no other meat". The common use association between such diets and vegetarianism has led groups such as the Vegetarian Society to state that diets containing these foods are not vegetarian.
Caesioperca is a genus of ray-finned fish in the sub-family Anthiadinae in the sea bass family Serranidae. It contains just two species, found in the ocean off Southern Australia and New Zealand.
