Cod Fishery
Cod fisheries are fisheries for cod. Cod is the common name for fish of the genus ''Gadus'', belonging to the family (biology), family Gadidae, and this article is confined to three species that belong to this genus: the Atlantic cod, the Pacific cod and the Greenland cod. Although there is a fourth species of the cod genus ''Gadus'', Alaska pollock, it is commonly not called cod and therefore currently not covered here. Cod are demersal fish found in huge Shoaling and schooling, schools confined to temperate waters in the northern hemisphere. Atlantic cod are found in the colder waters and deeper sea regions throughout the Atlantic Ocean, Northern Atlantic. The Pacific cod is found in both eastern and western regions of the Pacific Ocean, Pacific. Atlantic cod can grow to in length. Its average weight is , but specimens weighing up to have been recorded. Pacific cod are smaller, and may grow up to and weigh up to . Cod feed on mollusks, crabs, starfish, worms, squid, and small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fisheries
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.

Fish And Chips
Fish and chips is a popular hot dish consisting of fried fish in crispy batter, served with chips. The dish originated in England, where these two components had been introduced from separate immigrant cultures; it is not known who created the culinary fusion that became the emblematic British meal. Often considered Britain's national dish, fish and chips is a common take-away food in the United Kingdom and numerous other countries, particularly in English-speaking and Commonwealth nations. Fish and chip shops first appeared in the UK in the 1860s, and by 1910, there were over 25,000 fish and chip shops across the UK. By the 1930s there were over 35,000 shops, but the trend reversed, and by 2009 there were only approximately 10,000. The British government safeguarded the supply of fish and chips during the First World War, and again in the Second World War; it was one of the few foods in the UK not subject to rationing during the wars.

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mackerel
Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment. Mackerel species typically have deeply forked tails and vertical 'tiger-like' stripes on their backs with an Iridescence, iridescent green-blue quality. Many are restricted in their distribution ranges and live in separate populations or Fish stocks, fish stocks based on geography. Some stocks Fish migration, migrate in large Shoaling and schooling, schools along the coast to suitable spawning grounds, where they spawn in fairly shallow waters. After spawning they return the way they came in smaller schools to suitable feeding grounds, often near an area of upwelling. From there they may move offshore into deeper waters and spend the winter in relative inactivity. Other stocks migrate across oceans. Smaller mackerel are forage fish for lar ...

Worm
Worms are many different distantly related bilateral animals that typically have a long cylindrical tube-like body, no limbs, and no eyes (though not always). Worms vary in size from microscopic to over in length for marine polychaete worms (bristle worms); for the African giant earthworm, ''Microchaetus rappi''; and for the marine nemertean worm (bootlace worm), ''Lineus longissimus''. Various types of worm occupy a small variety of parasitic niches, living inside the bodies of other animals. Free-living worm species do not live on land but instead live in marine or freshwater environments or underground by burrowing. In biology, "worm" refers to an obsolete taxon, ''vermes'', used by Carolus Linnaeus and Jean-Baptiste Lamarck for all non-arthropod invertebrate animals, now seen to be paraphyletic. The name stems from the Old English word ''wyrm''. Most animals called "worms" are invertebrates, but the term is also used for the amphibian caecilians and the slowworm '' A ...

Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and Freshwater bivalve, freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong Byssus, byssal threads ("beard") to a firm substrate. A few species (in the genus ''Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobster
Lobsters are a family (biology), family (Nephropidae, Synonym (taxonomy), synonym Homaridae) of marine crustaceans. They have long bodies with muscular tails and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in coastal areas they populate. Commercially important species include two species of ''Homarus'' from the northern Atlantic Ocean and scampi (which look more like a shrimp, or a "mini lobster")—the Northern Hemisphere genus ''Nephrops'' and the Southern Hemisphere genus ''Metanephrops''. Distinction Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the family Nephropidae. Clawed lobsters are not closely related to spiny lobsters o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

Whiting (fish)
A number of Actinopterygiian fish have been given the common name whiting. Gadiformes (cod-like) * The fish originally known by the name "whiting" in English is ''Merlangius merlangus'', in the family Gadidae. This species inhabits the eastern Atlantic Ocean and the Mediterranean Sea, as well as the North Sea on the East Coast of Britain. In the United States, it is commonly known as the English whiting. * In Canada, it is used for the Alaska pollock, ''Theragra chalcogramma''. * In the Southern Ocean, it is used for the southern blue whiting. * In the US, the name whiting on its own is often used for various species of hake in the genus ''Merluccius''. Sciaenidae * Species ''Menticirrhus americanus'' (also known as the Carolina whiting, king whiting, sea mullet, southern kingcroaker, and southern kingfish) found along the Atlantic and Gulf Coasts of the United States. Smelt-whitings * In Australia, India, and throughout the Indo-Pacific, the name whiting is used for fish in the fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Eel
Sand eel or sandeel is the common name used for a considerable number of species of fish. While they are not true eels, they are eel-like in their appearance and can grow up to in length. Many species are found off the western coasts of Europe from Spain to Scotland, and in the Mediterranean and Baltic seas. Sand eels are an important food source for seabirds, including puffins and kittiwakes. They are a commercially important for the production of fish meal and made up 4% of fish globally caught for fish meal production (behind anchovy, capelin and blue whiting) between 1997 and 2001. Habitat The preferential habitat for sand eels is a seabed floor, with a relatively smooth bottom of gravelly sand; an example of this prime habitat is the floor of the Sea of the Hebrides. Sand eel species Most sand eels are sea fish of the genera ''Hyperoplus'' (greater sand eels), ''Gymnammodytes'' or ''Ammodytes''. The three genera listed above all fall within the family Ammodytidae, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basque Country (greater Region)
The Basque Country ( eu, Euskal Herria; es, País Vasco; french: Pays basque) is the name given to the home of the Basque people. Trask, R.L. ''The History of Basque'' Routledge: 1997 The Basque country is located in the western Pyrenees, straddling the border between France and Spain on the coast of the Bay of Biscay. ''Euskal Herria'' is the oldest documented Basque name for the area they inhabit, dating from the 16th century. It comprises the Autonomous Communities of the Basque Country and Navarre in Spain and the Northern Basque Country in France. The region is home to the Basque people ( eu, Euskaldunak), their language ( eu, Euskara), culture and traditions. The area is neither linguistically nor culturally homogeneous, and certain areas have a majority of people who do not consider themselves Basque, such as the south of Navarre. The concept is still highly controversial, and the Supreme Court of Navarre has ruled against scholarly books that include the Navarre c ...
