Chionoecetes Bairdi
''Chionoecetes bairdi'' is a species of snow crab, alternatively known as bairdi crab and tanner crab. ''C. bairdi'' is closely related to ''Chionoecetes opilio'', and it can be difficult to distinguish ''C. opilio'' from ''C. bairdi''. Both species are found in the Bering Sea and are sold commercially under the name "Snow crab." Tanner crabs have suffered from overfishing and as a result strict controls have been placed on tanner crab fisheries. It was named by Mary Jane Rathbun, a Smithsonian employee who became one of the leading authorities on crab taxonomy. She named the crab for Spencer Baird, her mentor, who in the 1880s as Secretary of the Smithsonian Institution and head of the United States Fish Commission, had given her her first position. Biology Tanner crabs are considered a short-tailed or "true" crab. They are decapods with pincer claws on their frontmost pair of legs. They can live over a decade with most adults reaching by the time they reach adulthood, usual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Crab
''Chionoecetes'' is a genus of crabs that live in the northern Pacific and Atlantic Oceans. The genus ''Chionoecetes'' currently contains seven distinct species. Other names for crabs in this genus include "queen crab" (in Canada) and "spider crab" – they are known by different names in different areas of the world. The generic name ''Chionoecetes'' means snow (, ') inhabitant (, '); ' means shepherd, and '' C. opilio'' is the primary species referred to as snow crab. Marketing strategies, however, employ snow crab for any species in the genus ''Chionoecetes''. The name "snow crab" refers to their being commonly found in cold northern oceans. General Snow crab are caught as far north as the Arctic Ocean, from Newfoundland to Greenland and north of Norway in the Atlantic Ocean, and across the Pacific Ocean, including the Sea of Japan, the Bering Sea, the Gulf of Alaska, Norton Sound, and even as far south as California for ''Chionoecetes bairdi''.

Hematodinium
''Hematodinium'' is a Genus, genus of dinoflagellates. Species in this genus, such as ''Hematodinium perezi'', the type species, are internal parasitism, parasites of the hemolymph of crustaceans such as the Atlantic blue crab (''Callinectes sapidus'') and Norway lobster (''Nephrops norvegicus''). Species in the genus are economically damaging to commercial crab fisheries, including causing bitter crab disease in the large Chionoecetes bairdi, Tanner or snow crab fisheries of the Bering Sea. Introduction ''Hematodinium'' is a harmful parasitic dinoflagellate in marine decapod crustaceans, often dwelling in the hemolymph of host organisms . Drastic changes in the host’s vital organs, tissues, and hemolymph lead to the degeneration of the organism . Previous studies indicate that species in genus ''Hematodium'' affect many organisms in Order Decapoda, and may also affect Order Amphipoda and subclass Copepoda (Manier ''et al'', 1971). These crustacean taxa include crabs, lobste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustaceans Of The Eastern Pacific Ocean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their ...

Majoidea
The Majoidea are a Superfamily (taxonomy), superfamily of crabs which includes the various spider crabs. Taxonomy In "''A classification of living and fossil genera of decapod crustaceans''" De Grave and colleagues divided Majoidea into six families: * Family Epialtidae ** Subfamily Epialtinae ** Subfamily Pisinae ** Subfamily Pliosomatinae ** Subfamily Tychiinae * Family Hymenosomatidae * Family Inachidae * Family Inachoididae * Family Majidae ** Subfamily Eurynolambrinae ** Subfamily Majinae ** Subfamily Micromaiinae ** Subfamily Mithracinae ** Subfamily Planoterginae * Family Oregoniidae The classification has since been revised, with subfamilies Epialtinae and Mithracinae being elevated to families and Hymenosomatidae being moved to its own superfamily. The family composition according to the World Register of Marine Species is as follows: * family Epialtidae MacLeay, 1838 * family Inachidae MacLeay, 1838 * family Inachoididae Dana, 1851 * family Macrocheiridae Dana, 1851 ...

Individual Fishing Quota
Individual fishing quotas (IFQs), also known as "individual transferable quotas" (ITQs), are one kind of ''catch share'', a means by which many governments regulate fishing. The regulator sets a species-specific total allowable catch (TAC), typically by weight and for a given time period. A dedicated portion of the TAC, called quota shares, is then allocated to individuals. Quotas can typically be bought, sold and leased, a feature called transferability. As of 2008, 148 major fisheries (generally, a single species in a single fishing ground) around the world had adopted some variant of this approach, along with approximately 100 smaller fisheries in individual countries. Approximately 10% of the marine harvest was managed by ITQs as of 2008. The first countries to adopt individual fishing quotas were the Netherlands, Iceland and Canada in the late 1970s, and the most recent is the United States Scallop General Category IFQ Program in 2010. The first country to adopt individual transf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

King Crab
King crabs are a taxon of decapod crustaceans chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food, the most common being the red king crab (''Paralithodes camtschaticus''). King crabs are generally thought to be derived from hermit crab-like ancestors within the Paguridae, which may explain the asymmetry still found in the adult forms. This ancestry is supported by several anatomical peculiarities which are present only in king crabs and hermit crabs. Although some doubt still exists about this hypothesis, king crabs are the most widely quoted example of carcinisation among the Decapoda. The evidence for this explanation comes from the asymmetry of the king crab's abdomen, which is thought to reflect the asymmetry of hermit crabs, which must fit into a spiral shell. Controversial taxon Although formerly classified among the hermit crabs in the superfamily Paguroidea, king crabs are now placed in a ...
