Gadiculus Argenteus
''Gadiculus argenteus'', or the silvery pout, is a species of cod found in the Northeast Atlantic region. It grows to a length of and is of minor importance to local commercial fisheries, being rather used as a bait fish. ''Gadiculus argenteus'' was until recently considered the only species in the genus ''Gadiculus'', known as the silvery pouts, but composed of two subspecies, ''G. a. argentatus'' and ''G. a. thori''. Currently, they are considered two separate species with different distributions: ''G. argenteus'' is more southerly, occurring in the western Mediterranean and in the Atlantic around the Strait of Gibraltar and to the south along the Moroccan coast, while '' G. thori'' is found from the Bay of Biscay north up to the North Cape.PAM Gaemers, JY Poulsen (2017Recognition and Distribution of Two North Atlantic ''Gadiculus'' Species, ''G. argenteus'' and ''G. thori'' (Gadidae), Based on Otolith Morphology, Larval Pigmentation, Molecular Evidence, Morphometrics and Me ...

Alphone Guichenot
Antoine Alphonse Guichenot (31 July 1809 in Paris – 17 February 1876 in Cluny) was a French zoologist who taught, researched, and participated in specimen collecting trips on behalf of the ''Muséum national d'histoire naturelle'' (Paris), including an extensive biological survey of Algeria. His primary fields of research included fish and reptiles. He is credited with describing the ichthyological genera '' Agonomalus'', '' Neosebastes'' (gurnard scorpionfishes) and ''Glossanodon''.Publications: University series, Volumes 36-40 by Stanford University He also described numerous new species, including the New Caledonian crested gecko, ''Correlophus ciliatis'' (changed to ''Rhaco ...

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] |
Commercial Fisheries
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is also known as industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well. In order to adapt to declining fish populations and increased demand, many commercial fishing operations have reduced the sustainability of their harvest by fishing further down the food chain. This raises concern for fishery managers and researchers, who highlight how further they say that for those reasons, the sustainability of the marine ecosystems could be in danger of collapsing. Commercial fishermen harvest a wide variety of animals. However, a very small number of species support the majority of the world' ...

Bait Fish
300px, Feeder Goldfish are common baitfish. Bait fish (or baitfish) are small-sized fish caught and used by anglers as bait to attract larger predatory fish, particularly game fish. Baitfish species are typically those that are common and breed rapidly, making them easy to catch and in abundant supply. Overview Examples of marine bait fish are anchovies, gudgeon, halfbeaks such as ballyhoo, and scad. Some larger fish such as menhaden, flying fish or ladyfish may be considered bait fish in some circles, depending on the size of the gamefish being pursued. Freshwater bait fish include minnows from the carp family (Cyprinidae), sucker family (Catostomidae), topminnows from the killifish suborder (Cyprinodontoidei), shad family (Clupeidae), sculpin of the order Scorpaeniformes and sunfish family (Centrarchidae), excluding black basses and crappies. Bait fish can be contrasted with forage fish. ''Bait fish'' is a term used particularly by recreational fishermen, although commer ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Strait Of Gibraltar
The Strait of Gibraltar ( ar, مضيق جبل طارق, Maḍīq Jabal Ṭāriq; es, Estrecho de Gibraltar, Archaic: Pillars of Hercules), also known as the Straits of Gibraltar, is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa. The two continents are separated by of ocean at the Strait's narrowest point between Point Marroquí in Spain and Point Cires in Morocco. Ferries cross between the two continents every day in as little as 35 minutes. The Strait's depth ranges between which possibly interacted with the lower mean sea level of the last major glaciation 20,000 years ago when the level of the sea is believed to have been lower by . The strait lies in the territorial waters of Morocco, Spain, and the British overseas territory of Gibraltar.

Gadiculus Thori
''Gadiculus thori'' is a species of cod found in the northeastern Atlantic Ocean. It grows to a length of and is not of major importance to local commercial fisheries. ''Gadiculus thori'' was until recently considered a subspecies of the more widely distributed silvery pout, ''Gadiculus argenteus''. Currently, the distribution of ''G. argenteus'' is thought to be more southerly, in the western Mediterranean and the adjacent Atlantic, while ''G. thori'' is found from the Bay of Biscay north up to the North Cape.PAM Gaemers, JY Poulsen (2017Recognition and Distribution of Two North Atlantic ''Gadiculus'' Species, ''G. argenteus'' and ''G. thori'' (Gadidae), Based on Otolith Morphology, Larval Pigmentation, Molecular Evidence, Morphometrics and MeristicsFishes, 2(3), 15; doi:10.3390/fishes2030015 In |
