Alaska Blackfish
The Alaska blackfish (''Dallia pectoralis'') is a species of freshwater fish in the esocid family (Esocidae) of order Esociformes. It inhabits Arctic regions of Alaska as well as Siberia and the Bering Sea islands. Description Alaska blackfish are small, with an average length of , but have been known to reach . They have an easily distinguishable morphology (a branch of biology dealing with the study of the form and structure of organisms and their specific structural features), with relatively large, posterior dorsal fin and anal fins, large, lobed pectoral fins located just posterior to the operculum, a diphycercal caudal fin, and small, pointy pelvic fins. The head is broad and flat, with the trunk being long and slender. The color is dark green to brown on the dorsal side, pale below, with light-colored blotches appearing laterally. Males can be distinguished from females by the presence of a reddish fringe along the dorsal, caudal, and anal fins; also, the tips of the ...

Many-toothed Blackfish
The melon-headed whale (''Peponocephala electra''), also known less commonly as the electra dolphin, little killer whale, or many-toothed blackfish, is a toothed whale of the oceanic dolphin family (Delphinidae). The common name is derived from the head shape. Melon-headed whales are widely distributed throughout deep tropical and subtropical waters worldwide, but they are rarely encountered at sea. They are found near shore mostly around oceanic islands, such as Hawaii, French Polynesia, and the Philippines. Taxonomy The melon-headed whale is the only member of the genus ''Peponocephala''. First recorded from a specimen collected in Hawaiʻi in 1841, the species was originally described as a member of the dolphin family and named ''Lagenorhynchus electra'' by John Edward Gray in 1846. The melon-headed whale was later determined to be sufficiently distinct from other ''Lagenorhynchus'' species to be accorded its own genus. A member of the subfamily Globicephalinae, melon-headed wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilot Whale
Pilot whales are cetaceans belonging to the genus ''Globicephala''. The two extant species are the long-finned pilot whale (''G. melas'') and the short-finned pilot whale (''G. macrorhynchus''). The two are not readily distinguishable at sea, and analysis of the skulls is the best way to distinguish between the species. Between the two species, they range nearly worldwide, with long-finned pilot whales living in colder waters and short-finned pilot whales living in tropical and subtropical waters. Pilot whales are among the largest of the oceanic dolphins, exceeded in size only by the orca. They and other large members of the dolphin family are also known as blackfish. Pilot whales feed primarily on squid, but will also hunt large demersal fish such as cod and turbot. They are highly social and may remain with their birth pod throughout their lifetime. Short-finned pilot whales are one of the few mammal species in which females go through menopause, and postreproductive females ...

Tautoga Onitis
The tautog (''Tautoga onitis''), also known as the blackfish, is a species of wrasse native to the western Atlantic Ocean from Nova Scotia to South Carolina. This species inhabits hard substrate habitats in inshore waters at depths from . It is currently the only known member of its genus. Barlett (1848) wrote, " autaugis a Native American word, and may be found in Roger Williams' ''Key to the Indian Language''." The name is from the Narragansett language, originally ''tautauog'' (pl. of ''taut''). It is also called a "black porgy" (''cf.'' Japanese black porgy), "chub" (''cf.'' the freshwater chub), "oyster-fish" (in North Carolina) or "blackfish" (in New York/New Jersey, New England). Description Tautog are brown and dark olive, with white blotches, and have plump, elongated bodies. They have an average weight of and reach a maximum length and weight of and respectively. Tautog have many adaptations to life in and around rocky areas. They have thick, rubbery lips and powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacramento Blackfish
The Sacramento blackfish (''Orthodon microlepidotus'') is a species of freshwater fish in central California. A cyprinid, the blackfish is the sole member of its genus. Distribution and habitat Blackfish are primarily denizens of the warm and cloudy waters found on the floor of the Central Valley, such as sloughs and oxbow lakes connected to the Sacramento and San Joaquin Rivers. They are also common in Clear Lake, Pajaro River, Salinas River, the small creeks that feed into San Francisco Bay. A population is present in the Russian River, believed to have been introduced. They also thrive in reservoirs, and have been spread to a number of California reservoirs via the California Aqueduct, and into Nevada via the Lahontan Reservoir (1964) where they have further colonized the Humboldt River drainage.

Girella Tricuspidata
The parore (''Girella tricuspidata'') also known as luderick, black bream or blackfish is a species of marine ray-finned fish, a sea chub from the family Kyphosidae which is found in the southwestern Pacific Ocean off Australia and New Zealand. Parore or paraore is the common name in New Zealand but in Australia luderick is preferred. Description The parore has a moderately deep, compressed, oval shaped body with a thin caudal peduncle, It has a small head which has a slightly convex forehead, and small eyes. The mouth is small and does not extend as far as the eye. The jaws have an outer row of overlapping, flattened, tricuspid teeth beside a wide band of teeth of similar shape but which are tiny. Much of the body is covered im moderately small ctenoid scales and there is an arched lateral line, made up of 48-51 pored scales, which is parallel to the dorsal profile. It has a continuous dorsal fin which has no demarcation between its spiny and rayed parts. The spiny part has 14-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus). Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environmental source of food and commercial product which help to improve healthier habitats and used to recon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Bream
The Sparidae are a family of fish in the order Perciformes, commonly called sea breams and porgies. The sheepshead, scup, and red seabream are species in this family. Most sparids are deep-bodied compressed fish with a small mouth separated by a broad space from the eye, a single dorsal fin with strong spines and soft rays, a short anal fin, long pointed pectoral fins and rather large firmly attached scales. They are found in shallow temperate and tropical waters and are bottom-dwelling carnivores. There are hermaphrodites in the Sparidae. Protogyny and protandry appear sporadically through this lineage of fish. Simultaneous hermaphrodites and bi-directional hermaphrodites do not appear as much since Sparidae are found in shallower waters. Species of fish that express a hermaphroditic condition usually "lack a genetic hardwire", therefore ecological factors play a role in sex determination. Most species possess grinding, molar-like teeth. Eating the head is known to cause hallu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthopagrus Schlegelii
''Acanthopagrus schlegelii'', commonly known as the blackhead seabream, Japanese black porgy or sea bream, is a fish often farmed for food in Japan. It is one of the most popular fishes for game fishing in Japan. The body is ovoid and compressed, and its streamlined body makes it a fast swimmer. The mouth is small, terminal and with many incisor-like canines. It is an aggressive predator. The dorsal fin A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through conv ... has 10 to 12 spines and 10 to 15 soft rays, which are used for offence and defence.

Esocidae
Esocidae is a family of fish in the order Esociformes, which contains pike, pickerel, and mudminnows. While the family traditionally only contained the genus ''Esox'', recent genetic and paleontological research have recovered ''Novumbra'' and ''Dallia'' as members of the family Esocidae, being closer related to ''Esox'' than ''Umbra''. Fossil specimens from the Mesozoic in North America have been assigned as two additional genera in this family. Distribution Esocidae has a holarctic distribution. Species in the genus ''Esox'' can be found in Eurasia and North America, while ''Dallia'' has a more restricted range in Alaska and eastern Siberia. Of extant esocids, ''Novumbra'' has the most restricted range of all, being found only on the Olympic Peninsula in Washington state. Fossils of esocids ''Estesesox'' and ''Oldmanesox'' have been recovered in North America. '' Estesesox'' fossils have been described from the Lance, Hell Creek, Oldman, Foremost, and Milk River Formations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
