Merlucciidae
The Merlucciidae, commonly called merluccid hakes , are a family of cod-like fish, including most hakes. available for download at http://www.fao.org They are native to cold water in the Atlantic and Pacific Oceans, and typically are found at depths greater than in subtropical, temperate, sub-Arctic or sub-Antarctic regions. The best known species are in the genera ''Macruronus'' and ''Merluccius''. These predatory fish are up to in length, though most only reach about half that length, inhabiting the waters of the continental shelf and upper continental slope, where they feed on small fish such as lanternfishes. Several species are important commercial fish, for example the blue grenadier (''Macruronus novaezelandiae'') that is fished in the southwest Pacific and the North Pacific hake (''Merluccius productus'') that is fished off western North America. The taxonomy of the Merluccidae is not settled, with some authorities raising two or three subfamilies, the Merluccinae, Ma ...

Hake
The term hake refers to fish in the: * Family Merlucciidae of northern and southern oceans * Family Phycidae (sometimes considered the subfamily Phycinae in the family Gadidae) of the northern oceans Hake Hake is in the same taxonomic order (Gadiformes) as cod and haddock. It is a medium-to-large fish averaging from 0.5 to 3.6 kg (1 to 8 pounds) in weight, with specimens as large as 27kg (60lb). The fish can grow up to in length with a lifespan of as long as 14 years. Hake may be found in the Atlantic Ocean and Pacific Ocean in waters from deep. The fish stay in deep water during the day and come to shallower depths during the night. An undiscerning predator, hake feed on prey found near or on the bottom of the sea. Male and female hake are very similar in appearance. After spawning, the hake eggs float on the surface of the sea where the larvae develop. After a certain period of time, the baby hake then migrate to the bottom of the sea, preferring depths of less than . A tot ...

Blue Grenadier
The blue grenadier (also known as hoki, blue hake, New Zealand whiptail, or whiptail hake, ''Macruronus novaezelandiae'') is a merluccid hake of the family Merlucciidae found around southern Australia and New Zealand, as well as off both the Atlantic and Pacific coasts of South America from Peru to Brazil at depths of between . It feeds in midwater on small squids, crustaceans, and fish. Its length is between . It is a slender, silvery fish similar in appearance to the gemfish. The meat of the fish is white and almost always sold in fillets; culinarily it is considered a whitefish. Commercial use Australian supermarkets have many hoki products, mainly in pre-packaged processed foods. Often the manufactured meat result is manufactured into a fish cutlet shape and then battered or crumbed to further give a good fresh look. The hoki is one of the species used in McDonald's Filet-O-Fish, Fish Fingers and McFish sandwiches. It was previously served at Long John Silver's and Denny's ...

Macruronus
''Macruronus'' is a genus of merluccid hakes.

Steindachneria
The luminous hake (''Steindachneria argentea'') is a West Atlantic member of the Merluccidae family. It is the only member of its genus. Characteristics Luminous hake grow to a maximum of in total length. They have a silver colored body with slight brown coloring in dorsal areas, a purple tint ventrally, and a dark oral cavity. They have big eyes on a large head and a tapering body that ends in a point since they have no caudal fin. Their luminosity comes from a characteristic striated light organ on the sides of the head and lower (ventral) half of the body. The anus is found between the pelvic fins and is widely separated from the urogenital opening located anterior to the anal fin.Hoese, H. Dickson and Moore, Richard. (1998). “Fishes of the Gulf of Mexico: Texas, Louisiana, and Adjacent Waters” Luminous hake have uninterrupted lateral lines. They have a combined total of 18-20 gill rakers with five on the upper limb and 13-15 on the lower limb. The front of the first of t ...

Gadiformes
Gadiformes are an order of ray-finned fish, also called the Anacanthini, that includes the cod. Many major food fish are in this order. They are found in marine waters throughout the world and the vast majority of the species are found in temperate or colder regions (tropical species are typically deep-water). A few species may enter estuaries but only one, the burbot (''Lota lota''), is a freshwater fish. Common characteristics include the positioning of the pelvic fins (if present), below or in front of the pectoral fins. Gadiformes are physoclists, which means their swim bladders do not have a pneumatic duct. The fins are spineless. Gadiform fish range in size from the codlets, which may be as small as in adult length, to the Atlantic cod, ''Gadus morhua'', which reaches up to .

Continental Slope
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. The continental shelf is the relatively shallow water area found in proximity to continents. Continental margins constitute about 28% of the oceanic area. Zones of the continental margin The continental shelf is the portion of the continental margin that transitions from the shore out towards to ocean. Continental shelves are believed to make up 7% of the sea floor. The width of continental shelves worldwide varies in the range of 0.03–1500 km. The continental shelf is generally flat, and ends at the shelf break, where there is a drastic increase in slope angle: The mean angle of continental shelves worldwide is 0° 07′, and ...

Sensu Stricto
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypy
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...
