Diplodus Vulgaris
''Diplodus vulgaris'', the common two-banded sea bream, is a species of seabream belonging to the family Sparidae. Description ''Diplodus vulgaris'' can reach a length of about with maximum recorded weight of . Body is generally grey-silver, with two well-defined vertical black bands, one close to the gills and one in the rear of the body, just before the base of the caudal fin. Another black stripe, less pronounced, is present near the eyes. There are golden lines along the body, typically on the back. Lips are rather thick. In each jaw, there are 8 narrow, light-brownish incisors. In the western Mediterranean, it reproduces in October and November and in the eastern Mediterranean in December and January. It is a gregarious species, sometimes forming groups composed even by many specimens. In the shallows, it often creates smaller groups even with other similar species. Adults feed on benthic invertebrates, crustaceans, worms and mollusks. It is considered an important food f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Daubenton at the College de France and Fourcroy at the Jardin des Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabream
The Sparidae are a family of fish in the order Perciformes, commonly called sea breams and porgies. The sheepshead, scup, and red seabream are species in this family. Most sparids are deep-bodied compressed fish with a small mouth separated by a broad space from the eye, a single dorsal fin with strong spines and soft rays, a short anal fin, long pointed pectoral fins and rather large firmly attached scales. They are found in shallow temperate and tropical waters and are bottom-dwelling carnivores. There are hermaphrodites in the Sparidae. Protogyny and protandry appear sporadically through this lineage of fish. Simultaneous hermaphrodites and bi-directional hermaphrodites do not appear as much since Sparidae are found in shallower waters. Species of fish that express a hermaphroditic condition usually "lack a genetic hardwire", therefore ecological factors play a role in sex determination. Most species possess grinding, molar-like teeth. Eating the head is known to cause hallu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artisanal Fishing
Artisanal fishing (or traditional/subsistence fishing) consists of various small-scale, low-technology, low-capital, fishing practices undertaken by individual fishing households (as opposed to commercial fishing). Many of these households are of coastal or island ethnic groups. These households make short (rarely overnight) fishing trips close to the shore. Their produce is usually not processed and is mainly for local consumption. Artisan fishing uses traditional fishing techniques such as rod and tackle, fishing arrows and harpoons, cast nets, and small (if any) traditional fishing boats. For that reason, socio-economic status of artisanal fishing community has become an interest of the authorities in recent years. Artisan fishing may be undertaken for both commercial and subsistence reasons. It contrasts with large-scale modern commercial fishing practices in that it is often less wasteful and less stressful on fish populations than modern industrial fishing. Target 14.b ...

European Sea Bass
The European bass (''Dicentrarchus labrax'') is a primarily ocean-going fish native to the waters off Europe's western and southern and Africa's northern coasts, though it can also be found in shallow coastal waters and river mouths during the summer months. It is one of only six species in its family, Moronidae, collectively called the temperate basses. It is fished and raised commercially and is considered the most important fish currently cultured in the Mediterranean. In Ireland and the United Kingdom, the popular restaurant fish sold and consumed as sea bass is exclusively the European bass. In North America, it is widely known by one of its Italian names, branzino. European bass are a slow-growing species that take several years to reach adulthood. An adult European seabass usually weighs around . European bass can reach measurements of up to in length and in weight, though the most common size is only about half of that at . Individuals are silvery grey and sometimes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dentex Dentex
The common dentex (''Dentex dentex'') is a species of fish in the family Sparidae. Etymology Genus and species Latin name ''Dentex'' is related to ''dentēs'' which means "teeth". Description Adult dentex can reach a length of , and weight up to . The body is oval and compressed. Teeth are very developed in each jaw. Dentex have 11 dorsal spines: 11–12 dorsal soft rays; 3 anal spines: 7–9 anal soft rays. Adults are grey-blue, while young dentex have a slightly different livery, brown-blue with blue fins. Biology Dentex is an active predator, feeding on other fish, mollusca and cephalopods. It is solitary for most of the year, but during reproduction it lives in groups for some weeks: fully-grown dentex stay together just two to three weeks during spring in the warmer water near the surface. Distribution and habitat Dentex is common in the Mediterranean Sea (called sinarit in Turkish), but also seen in the Black Sea and the Eastern Atlantic Ocean from the British ...

European Eel
The European eel (''Anguilla anguilla'') is a species of eel, a snake-like, catadromous fish. They are normally around and rarely reach more than , but can reach a length of up to in exceptional cases. Eels have been important sources of food both as adults (including jellied eels of East London) and as glass eels. Glass-eel fishing using basket traps has been of significant economic value in many river estuaries on the western seaboard of Europe. While the species' lifespan in the wild has not been determined, captive specimens have lived over 80 years. A specimen known as "the Brantevik Eel" lived for 155 years in the well of a family home in Brantevik, a fishing village in southern Sweden. Conservation status The European eel is a critically endangered species. Since the 1970s, the numbers of eels reaching Europe is thought to have declined by around 90% (possibly even 98%). Contributing factors include overfishing, parasites such as ''Anguillicola crassus'', bar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Of The East Atlantic
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...
