Merlangius Merlangus
''Merlangius merlangus'', commonly known as Whiting or merling, is an important food fish in the eastern North Atlantic Ocean and the northern Mediterranean, western Baltic, and Black Sea. In Anglophonic countries outside the Whiting's natural range, the name "whiting" has been applied to various other species of fish. Description ''Merlangius merlangus'' has three dorsal fins with a total of 30 to 40 soft rays and two anal fins with 30 to 35 soft rays. The body is long and the head small and a chin barbel, if present, is very small. This fish can reach a maximum length of about . The colour may be yellowish-brown, greenish or dark blue, the flanks yellowish grey or white and the belly silvery. There is a distinctive black blotch near the base of each pectoral fin. Distribution and habitat Whiting are native to the northeastern Atlantic Ocean. Their range extends from the southeastern Barents Sea and Iceland to Scandinavia, the Baltic Sea, the North Sea, Portugal, the Black S ...

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sinusoidal
A sine wave, sinusoidal wave, or just sinusoid is a mathematical curve defined in terms of the '' sine'' trigonometric function, of which it is the graph. It is a type of continuous wave and also a smooth periodic function. It occurs often in mathematics, as well as in physics, engineering, signal processing and many other fields. Formulation Its most basic form as a function of time (''t'') is: y(t) = A\sin(2 \pi f t + \varphi) = A\sin(\omega t + \varphi) where: * ''A'', ''amplitude'', the peak deviation of the function from zero. * ''f'', ''ordinary frequency'', the ''number'' of oscillations (cycles) that occur each second of time. * ''ω'' = 2''f'', ''angular frequency'', the rate of change of the function argument in units of radians per second. * \varphi, ''phase'', specifies (in radians) where in its cycle the oscillation is at ''t'' = 0. When \varphi is non-zero, the entire waveform appears to be shifted in time by the amount ''φ''/''ω'' seconds. A negative value rep ...

Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lernaeocera Branchialis
''Lernaeocera branchialis'', sometimes called cod worm, is a parasite of marine fish, found mainly in the North Atlantic. It is a marine copepod which starts life as a small pelagic crustacean larva. It is among the largest of copepods, ranging in size from when it matures as a copepodid larva to more than as a sessile adult. ''Lernaeocera branchialis'' is ectoparasitic, which means it is a parasite that lives primarily on the surface of its hosts. It has many life stages, some of which are motile and some of which are sessile. It goes through two parasitic stages, one where it parasitizes as a secondary host a flounder or lumpsucker, and another stage where it parasitizes as a primary host a cod or other fishes of the cod family (gadoids). It is a pathogen that negatively impacts the commercial fishing and mariculture of cod-like fish. Life stages The life-cycle of a cod worm involves a complex progression of life stages, including two successive hosts. It comprises "two fre ...

Gadidae
The Gadidae are a family of marine fish, included in the order Gadiformes, known as the cods, codfishes, or true cods. It contains several commercially important fishes, including the cod, haddock, whiting, and pollock. Most gadid species are found in temperate waters of the Northern Hemisphere, but several range into subtropical, subarctic, and Arctic oceans, and a single (southern blue whiting) is found in the Southern Hemisphere. They are generally medium-sized fish, and are distinguished by the presence of three dorsal fins on the back and two anal fins on the underside. Most species have barbels on their chins, which they use while browsing on the sea floor. Gadids are carnivorous, feeding on smaller fish and crustaceans. Gadids are highly prolific, producing several million eggs at each spawning. This contributes to their high population numbers, which, in turn, makes commercial fishing relatively easy. Concepts differ about the contents of the family Gadidae. The syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Wire
''The Wire'' is an American Crime film, crime drama Television show, television series created and primarily written by author and former police reporter David Simon. The series was broadcast by the cable network HBO in the United States. ''The Wire'' premiered on June 2, 2002, and ended on March 9, 2008, comprising 60 episodes over five seasons. The idea for the show started out as a police drama loosely based on the experiences of his writing partner Ed Burns, a former homicide detective and public school teacher. Set and produced in Baltimore, Maryland, ''The Wire'' introduces a different institution of the city and its relationship to law enforcement in each season, while retaining characters and advancing storylines from previous seasons. The five subjects are, in chronological order: the illegal drug trade, the port system, the city government and bureaucracy, education and schools, and the print news medium. Simon chose to set the show in Baltimore because of his familiar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Series
A television show – or simply TV show – is any content produced for viewing on a television set which can be broadcast via over-the-air, satellite television, satellite, or cable television, cable, excluding breaking news, television advertisement, advertisements, or Trailer (promotion), trailers that are typically placed between shows. Television shows are most often broadcast programming, scheduled for broadcast well ahead of time and appear on electronic program guide, electronic guides or other TV listings, but streaming services often make them available for viewing anytime. The content in a television show can be produced with different methodologies such as taped variety shows emanating from a television studio stage, animation or a variety of film productions ranging from movies to series. Shows not produced on a television studio stage are usually contracted or licensed to be made by appropriate production companies. Television shows can be viewed live (real time), b ...

Crime Drama
Crime films, in the broadest sense, is a film genre inspired by and analogous to the crime fiction literary genre. Films of this genre generally involve various aspects of crime and its detection. Stylistically, the genre may overlap and combine with many other genres, such as Drama (film and television), drama or gangster film, but also include Comedy film, comedy, and, in turn, is divided into many sub-genres, such as Mystery film, mystery, suspense or Film noir, noir. Screenwriter and scholar Eric R. Williams identified crime film as one of eleven super-genres in his Screenwriters Taxonomy, claiming that all feature-length Narrative film, narrative films can be classified by these super-genres. The other ten super-genres are action, fantasy, horror, romance, science fiction, slice of life, sports, thriller, war and western. Williams identifies drama in a broader category called "film type", mystery and suspense as "macro-genres", and film noir as a "screenwriter's pathway" ...

Mise-en-scène
''Mise-en-scène'' (; en, "placing on stage" or "what is put into the scene") is the stage design and arrangement of actors in scenes for a theatre or film production, both in visual arts through storyboarding, visual theme, and cinematography, and in narrative storytelling through direction. The term is also commonly used to refer to single scenes that are representative of a film. ''Mise-en-scène'' has been called film criticism's "grand undefined term." It has been criticized for its focus on the theatrical or dramatic design aspects rather than the plot itself, as those who utilize ''Mise-en-scène'' tend to look at what is "put before the camera," rather than the story. The use of ''mise-en-scène'' is significant as it allows the director to convey messages to the viewer through what is placed in the scene, not just the content of the scene. Definition in film studies When applied to the cinema, ''mise-en-scène'' refers to everything that appears before the camera and ...
