Merlucciidae
The merlucciidae, commonly called merluccid hakes , are a family of cod-like fish, including most hakes. 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, Macruroninae, and Steindachneriinae, while oth ...

Hake
Hake is the common name for fish in the Merlucciidae family of the northern and southern oceans and the Phycidae family of the northern oceans. Hake is a commercially important fish in the same taxonomic order, Gadiformes, as cod and haddock. Description Hakes are medium-to-large fish averaging from in weight, with specimens as large as . 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 . ''Merlucciidae'' A total of 13 hake species are know ...

Blue Grenadier
The blue grenadier (also known as hoki, blue hake, New Zealand whiptail, or whiptail hake, ''Macruronus novaezelandiae'') is a Merlucciidae, merluccid hake of the family (biology), family Merlucciidae found around southern Australia (continent), 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 Silver gemfish, gemfish. The meat of the fish is white and almost always sold in fillets; culinarily it is considered a whitefish (fisheries term), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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

Merluccius
''Merluccius'' is a genus of merluccid hakes from the Atlantic and Pacific Oceans, where mainly found relatively deep.

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. 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 two dorsal fins is the location of its one spine. The one anal fin is made up of a total of 123–125 soft rays. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gadiformes
Gadiformes , also called the Anacanthini, are an order of ray-finned fish that include the cod, hakes, pollock, haddock, burbot, rocklings and moras, many of which are food fish of major commercial value. They are mostly marine fish found throughout the world and the vast majority are found in temperate or colder regions (tropical species are typically deep-water) while a few species may enter brackish estuaries. Pacific tomcods, one of the two species that makes up the genus ''Microgadus'', are able to enter freshwater, but there is no evidence that they breed there. Some populations of landlocked Atlantic tomcod on the other hand, complete their entire life cycle in freshwater. Yet only one species, the burbot (''Lota lota''), is a true 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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Hake
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanternfish
Lanternfish (or myctophids, from the Greek language, Greek μυκτήρ ''myktḗr'', "nose" and ''ophis'', "serpent") are small mesopelagic fish of the large family (biology), family Myctophidae. One of two families in the order Myctophiformes, the Myctophidae are represented by 246 species in 33 genus, genera, and are found in oceans worldwide. Lanternfishes are aptly named after their conspicuous use of bioluminescence. Their sister family, the Neoscopelidae, are much fewer in number but superficially very similar; at least one neoscopelid shares the common name "lanternfish": the large-scaled lantern fish, ''Neoscopelus macrolepidotus''. Lanternfish are among the most widely distributed, diverse and populous vertebrates, with some estimates suggesting that they may have a total global Biomass (ecology), biomass of 1.8 to 16 gigatonnes, accounting for up to 65% of all deep-sea fish biomass. Commercial fisheries for them exist off South Africa, in the Antarctica, sub-Antarctic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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: * – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; * – "in the broad sense", abbreviation ''s.l.''; * – "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 of "more" or "most". Thus ''sensu strict ...
