Nototheniidae
: ''In some scientific literature, the term "cod icefish" is used to identify members of this family. This should not be confused with the term "icefish," which refers to the "white-blooded" fishes of the family Channichthyidae. See Icefish (other).'' Nototheniidae, the notothens or cod icefishes, is a family of ray-finned fishes, part of the suborder Notothenioidei which is traditionally placed within the order Perciformes. They are largely found in the Southern Ocean. Taxonomy Nototheniidae was described as a family in 1861 by the German-born British ichthyologist Albert Günther with the type genus being ''Notothenia'' which had been described in 1844 by Sir John Richardson with the species ''Notothenia coriiceps'' which Richardson had also described in 1844 subsequently being designated as the type in 1862 by Theodore Nicholas Gill. The name ''Notothenia'' means “coming from the south”, a reference to the Antarctic distribution of the genus. They are traditio ...

Pleuragramma
The Antarctic silverfish (''Pleuragramma antarctica''), or Antarctic herring, is a species of marine ray-finned fish belonging to the Family (biology), family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean and the only truly pelagic fish in the waters near Antarctica. It is a keystone species in the ecosystem of the Southern Ocean.Bottaro M., Oliveri D., Ghigliotti L., Pisano E., Ferrando S. & Vacchi M. (2009). "Born among the ice: first morphological observations on two developmental stages of the Antarctic silverfish ''Pleuragramma antarcticum'', a key species of the Southern Ocean". ''Reviews in Fish Biology and Fisheries'' 19(2); 249-259. . While widely distributed around the Antarctic, the species appears to have largely disappeared from the western side of the northern Antarctic Peninsula, based on a 2010 research cruise funded by the National Science Foundation under the US Antarctic Program.

Notothenia
''Notothenia'' is a genus of marine ray-finned fishes belonging to the family Nototheniidae, the notothens or cod icefishes with the species in this genus often having the common name of rockcod. They are native to the Southern Ocean and other waters around Antarctica. Taxonomy ''Notothenia'' was first formally described as a genus in 1844 by the Scottish naval surgeon, naturalist and Arctic explorer John Richardson when he described ''N. coriiceps'' which was later designated as the type species of the genus. Some authorities place this taxon in the subfamily Nototheniinae, but the 5th edition of ''Fishes of the World'' does not include subfamilies in the Nototheniidae. The name of the genus is a compound of ''notos'' meaning “south” and ''thenia'' which means “coming from”, an allusion to the high southern latitudes these fishes are found at. Species Seven recognized species are in this genus: * ''Notothenia angustata'' F. W. Hutton, 1875 (Maori chief) * ''Noto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobionotothen
''Gobionotothen'' is a genus of marine ray-finned fishes belonging to the family Nototheniidae, the notothens or cod icefishes. They are native to the Southern Ocean. Taxonomy ''Gobionotothen'' was first formally described in 1976 by the Russian ichthyologist Arkady Vladimirovich Balushkin with the type species designated as ''Notothenia gibberifrons'' which was described by the Swedish naturalist Einar Lönnberg in 1905 with its type locality given as South Georgia. Some authorities place this taxon in the subfamily Nototheniinae, but the 5th edition of '' Fishes of the World'' does not include subfamilies in the Nototheniidae. The name of the genus is a compound of ''gobio'' meaning “goby”, referring to the goby-like form of these species and ''notothen'', indicating that it is a nothothen. Species Five recognized species are in this genus: * '' Gobionotothen acuta'' ( Günther, 1880) (triangular rockcod) * '' Gobionotothen angustifrons'' ( J. G. Fischer, 1885) (narro ...

Dissostichus
''Dissostichus'', the toothfish, is a genus of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefish. These fish are found in the Southern Hemisphere. Toothfish are marketed in the United States as Chilean sea bass (or Chilean seabass) or less frequently as white cod. "Chilean sea bass" is a marketing name coined in 1977 by Lee Lantz, a fish wholesaler who wanted a more attractive name for selling the Patagonian toothfish to Americans. Retrieved on 16 May 2015.G. Bruce Knecht, ''Hooked: Pirates, Poaching, And the Perfect Fish", 2006. . p. 9'' In 1994, the U.S. Food and Drug Administration (FDA) accepted "Chilean sea bass" as an "alternative market name" for Patagonian toothfish. The toothfish was remarkably successful in the United States, Europe and Asia, and earned the nickname "white gold" within the market. Toothfish are vital to the ecological structure of Southern Ocean ecosystems. For this reason, on 4 September a national day is dedic ...

Gvozdarus
''Gvozdarus'' is a genus of marine ray-finned fishes belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean. Taxonomy ''Gvozdarus'' was first formally described as a genus in 1989 by the Soviet ichthyologist Arkady Vladimirovich Balushkin with the type species by monotypy being ''Gvozdarus svetovidovi'', a second species has subsequently been described. Some authorities place this taxon in the subfamily Pleuragrammatinae, but the 5th edition of ''Fishes of the World'' does not include subfamilies in the Nototheniidae. The name of the genus is a Latinised version of a local name for the zander (''Sander lucioperca'') in Veliky Novgorod, Russia. Balushkin did not explain why he chose this name but it may refer to the similarity in form of ''G. svetovidovi'', especially the long, pointed teeth, to the zander. Species The recognized species in this genus are: * '' Gvozdarus balushkini'' Voskoboinikova & Kellermann, 1993 * '' Gvoz ...

Lepidonotothen
The grey rockcod (''Lepidonotothen squamifrons''), also known as the grey notothen, stripe-eyes notothen or stripe-eyed rockcod, is a species of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean. The grey rockcod feeds mainly on macrozooplankton and is of minor importance to commercial fisheries. It is the only species in the genus ''Lepidonotothen''. Taxonomy The grey rockcod was first formally described in 1880 as ''Notothenia squamifrons'' by the German-born British ichthyologist Albert Günther with the type locality given as Kerguelen Island. The type was collected during the Challenger Expedition. In 1976 the Russian ichthyologist Arkady Vladimirovich Balushkin placed it in the genus ''Lepidonotothen'', this genus is currently regarded as monotypic with this species as its sole member. However, other authorities regard ''Lepidonotothen kempi'' as a valid species. Some authorities place this tax ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctic Toothfish
The Antarctic toothfish (''Dissostichus mawsoni'') is a large, black or brown fish found in very cold (subzero) waters of the Southern Ocean near Antarctica. It is the largest fish in the Southern Ocean, feeding on shrimp and smaller fish, and preyed on by whales, orcas, and seals. It is caught for food and marketed as Chilean sea bass together with its sister species, the more northerly Patagonian toothfish (''D. eliginoides''). Often mistakenly called "Antarctic cod," the Antarctic toothfish belongs to the notothen family (Nototheniidae), a group of fish species abundant near Antarctica. Name and taxonomy The common name "toothfish" refers to the two rows of teeth in the upper jaw, thought to give it a shark-like appearance. The genus name ''Dissostichus'' is from the Greek (twofold) and ''stichus'' (line) and refers to the presence of two long lateral lines that enable the fish to sense prey. The species name, ''mawsoni'', honors the Australian geologist Douglas Mawson who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aethotaxis
The longfin icedevil (''Aethotaxis mitopteryx''), also known as the threadfin pinhead, is a species of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean where it can be found at depths down to . This species grows to a length of TL. This species is the only known member of its genus and is of no interest to commercial fisheries. Taxonomy The longfin icedevil was first formally described in 1962 by the American ichthyologist Hugh H. DeWitt with the type locality given as off Pram Point on Ross Island in McMurdo Sound, Antarctica at 77°53'S, 166°44'E, the type being picked up dead at the surface. Dewitt placed the new species in the monotypic genus ''Aethotaxis'' in which it is still the only species. The species is sometimes split into 2 subspecies, with ''A.m. pawsoni'' proposed as a subspecies in the Weddell Sea and the Scotia Sea but this requires more evidence.

Notothenia Coriiceps
''Notothenia coriiceps'', also known as the black rockcod, Antarctic yellowbelly rockcod, or Antarctic bullhead notothen, is a species of marine ray-finned fish, belonging to the family Nototheniidae, the notothens or cod icefishes. It is widely spread around the Antarctic continent.Eastman, Joseph (1993). ''Antarctic Fish Biology: Evolution in a Unique Environment''. San Diego, California: Academic Press, In Like other Antarctic notothenioid fishes, ''N. coriiceps'' evolved in the stable, ice-cold environment of the Southern Ocean. It is not currently targeted by commercial fisheries. Taxonomy ''Notothenia coriiceps'' was first formally described in 1844 by the Scottish naval surgeon, naturalist and Arctic explorer John Richardson with the type locality given as the coasts of the Kerguelen Islands and the Auckland Islands. Richardson named a new genus, ''Notothenia'', in his description and this species was designated as its type species by Theodore Nicholas Gill in 1862. ...

Notothenioidei
Notothenioidei is one of 19 suborders of the order Perciformes. The group is found mainly in Antarctic and Subantarctic waters, with some species ranging north to southern Australia and southern South America. Notothenioids constitute approximately 90% of the fish biomass in the continental shelf waters surrounding Antarctica. Evolution and geographic distribution The Southern Ocean has supported fish habitats for 400 million years; however, modern notothenioids likely appeared sometime after the Eocene epoch. This period marked the cooling of the Southern Ocean, resulting in the stable, ice-cold conditions that have persisted to the present day. Another key factor in the evolution of notothenioids is the preponderance of the Antarctic Circumpolar Current (ACC), a large, slow-moving current that extends to the seafloor and precludes most migration to and from the Antarctic region. These unique environmental conditions in concert with the key evolutionary innovation of Antif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perciformes
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". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...
