Halibut
Halibut is the common name for three flatfish in the genera '' Hippoglossus'' and ''Reinhardtius'' from the family of right-eye flounders and, in some regions, and less commonly, other species of large flatfish. The word is derived from ''haly'' (holy) and ''butte'' (flat fish), for its popularity on Catholic holy days. Halibut are demersal fish and are highly regarded as a food fish as well as a sport fish. Species A 2018 cladistic analysis based on genetics and morphology showed that the greenland halibut diverged from a lineage that gave rise to the Atlantic and Pacific halibuts. The common ancestor of all three diverged from a lineage that gave rise to the genus '' Verasper'', comprising the spotted halibut and barfin flounder. * Genus '' Hippoglossus'' ** Atlantic halibut, ''Hippoglossus hippoglossus'' – lives in the North Atlantic ** Pacific halibut, ''Hippoglossus stenolepis'' – lives in the North Pacific Ocean * Genus ''Reinhardtius'' **Greenland halib ...

Hippoglossus Hippoglossus
The Atlantic halibut (''Hippoglossus hippoglossus'') is a flatfish of the family Pleuronectidae. They are demersal fish living on or near sand, gravel or clay bottoms at depths of between . The halibut is among the largest teleost (bony) fish in the world, and is a threatened species due to a slow rate of growth and overfishing. Halibut are strong swimmers and are able to migrate long distances. Halibut size is not age-specific, but rather tends to follow a cycle related to halibut (and therefore food) abundance. The native habitat of the Atlantic halibut is the temperate and arctic waters of the northern Atlantic, from Labrador and Greenland to Iceland, the Barents Sea and as far south as the Bay of Biscay and Virginia. It is the largest flatfish in the world, reaching lengths of up to and weights of . Its lifespan can reach 50 years. Age can be estimated by counting the rings laid down inside the otolith – a bony structure found inside the inner ear of the fish. Descriptio ...

Fish As Food
Many species of fish are caught by humans and consumed as food in virtually all regions around the world. Fish has been an important dietary source of protein and other nutrients throughout human history. The English language does not have a special culinary name for food prepared from fish like with other animals (as with ''pig'' vs. ''pork''), or as in other languages (such as Spanish ''pez'' vs. '' pescado''). In culinary and fishery contexts, ''fish'' may include so-called shellfish such as molluscs, crustaceans, and echinoderms; more expansively, seafood covers both fish and other marine life used as food. Since 1961, the average annual increase in global apparent food fish consumption (3.2 percent) has outpaced population growth (1.6 percent) and exceeded consumption of meat from all terrestrial animals, combined (2.8 percent) and individually (bovine, ovine, porcine, etc.), except poultry (4.9 percent). In ''per capita'' terms, food fish consumption has grown from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatfish
A flatfish is a member of the Ray-finned fish, ray-finned demersal fish order (biology), order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. Many important food fish are in this order, including the flounders, sole (fish), soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Over 800 described species are placed into 16 families. Broadly, the flatfishes are divided into two suborders, Psettodoidei and Pleuronectoidei, with > 99% of the species diversity found within the Pleuronectoidei. The largest families are Soleidae, Bothidae and Tonguefish, Cynoglossidae with more than 150 species each. There also exist two monotypic families (P ...

Reinhardtius
The Greenland halibut or Greenland turbot (''Reinhardtius hippoglossoides'') belongs to the family Pleuronectidae (the right-eye flounders), and is the only species of the genus ''Reinhardtius''. It is a predatory fish that mostly ranges at depths between , and is found in the cold northern Atlantic, northern Pacific, and Arctic Oceans. It has a variety of other English vernacular names, including black halibut, blue halibut, lesser halibut, and Newfoundland turbot; while both Newfoundland turbot and Greenland turbot are in common use in North America (sometimes even without the location, just "turbot"), these names are typically not used in Europe, where they can cause easy confusion with the true turbot (''Scophthalmus maximus''). The Greenland halibut is fished commercially across its range with disputes over the fishing rights for this species in the Atlantic Ocean off Canada resulting in the Turbot War of the mid-1990s (a "war" without any injuries or casualties).

Alaska 2007 071
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Central Alaskan Yup'ik language, Yup'ik: ''Alaskaq''; tli, Anáaski) is a U.S. state, state located in the Western United States on the northwest extremity of North America. A enclave and exclave, semi-exclave of the U.S., it borders the Provinces and territories of Canada, Canadian province of British Columbia and the Yukon territory to the east; it also shares a Maritime boundary, maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait.

Hippoglossus
''Hippoglossus'' is a genus of very large righteye flounders with one species native to the north Atlantic Ocean and one to the north Pacific Ocean. Etymology The word ''hippoglossus'' is derived from the Greek language, Greek ἵππος (''hippos''), meaning "horse", and γλῶσσα (''glōssa''), meaning "tongue" - a reference to the shape of the fish. Species There are two species in this genus: * ''Atlantic halibut, Hippoglossus hippoglossus'' (Carl Linnaeus, Linnaeus, 10th edition of Systema Naturae, 1758) (Atlantic halibut) * ''Pacific halibut, Hippoglossus stenolepis'' Peter Yulevich Schmidt, P.

IGFA
The International Game Fish Association (''IGFA'') is the leading authority on angling pursuits and the keeper of the most current World Record fishing catches by fish categories. Fishermen who are sport fishers are careful to follow their stringent rules for fair play and line requirements in order to receive the honor of being listed in their annual "World Record Game Fishes" publication. The publication also gives fishing tips, and has an extensive fish identification guide. The IGFA is also an ardent proponent of aquatic habitat conservation, and cooperates with biologists all over the world. It is considered the world’s governing body for sport fishing. IGFA is headquartered in Dania Beach, Florida. Philosophy IGFA's objectives are founded on the beliefs that game fish species, related food fish, and their habitats are economic, social, recreational, and aesthetic assets which must be maintained, wisely used and perpetuated; and that the sport of angling is an important ...

Pacific Halibut
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Hermit Crab
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless. The strong association between hermit crabs and their shelters has significantly influenced their biology. Almost 800 species carry mobile shelters (most often calcified snail shells); this protective mobility contributes to the diversity and multitude of crustaceans found in almost all marine environments. In most species, development involves metamorphosis from symmetric, free-swimming larvae to morphologically asymmetric, benthic-dwelling, shell-seeking crabs. Such physiological and behavioral extremes facilitate a transition to a sheltered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
