Gilt-head Bream
The gilt-head bream (''Sparus aurata''), also known as the gilthead, dourade, gilt-head seabream or silver seabream, is a species of marine Actinopterygii, ray-finned fish belonging to the Family (biology), family Sparidae, the seabreams or porgies. This fish is found in the Eastern Atlantic and the Mediterranean. It is a highly esteemed food fish and an important species in aquaculture. Taxonomy The gilt-head bream was first formally Species description, described in 1758 by Carl Linnaeus in the 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'' with its type locality given as the Mediterranean and Venezuela (although this has now been shown to be a specimen of ''Calamus (fish), Calamus''). It is the only species in the monospecific genus ''Sparus''. The genus ''Sparus'' is placed in the family Sparidae within the Order (biology), order Spariformes by the 5th edition of ''Fishes of the World''. Some authorities classify this genus in the subfamily Sparinae, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provence-Alpes-Côte D'Azur
Provence-Alpes-Côte d'Azur (commonly shortened to PACA), also known as Région Sud, is one of the eighteen Regions of France, administrative regions of France, located at the far southeastern point of the Metropolitan France, mainland. The main Prefectures in France, prefecture and largest city is Marseille, France's third largest city after Paris and Lyon and the 2nd largest urban area when combined with Aix-en-Provence with slightly less than one million residents. History The region is roughly coterminous with the former Provinces of France, French province of Provence, with the addition of the following adjacent areas: the former Pope, papal territory of Avignon, known as Comtat Venaissin; the former Kingdom of Sardinia, Sardinian-Piedmontese County of Nice annexed in 1860, whose coastline is known in English as the French Riviera and in French as the ''Côte d'Azur''; and the southeastern part of the former French province of Dauphiné, in the French Alps.

Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. Nelumbo nucifera, lotus). Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems. Mariculture, commonly known as marine farming, is aquaculture in seawater habitats and lagoons, as opposed to freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain Fish as food, fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environme ...

Shellfish
Shellfish, in colloquial and fisheries usage, are exoskeleton-bearing Aquatic animal, aquatic invertebrates used as Human food, food, including various species of Mollusca, molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from Seawater, saltwater environments, some are found in freshwater. In addition, a few species of land crabs are eaten, for example ''Cardisoma guanhumi'' in the Caribbean. Shellfish are among the most common food allergy, food allergens. Despite the name, shell''fish'' are not fish. Most shellfish are Trophic level, low on the food chain and eat a diet composed primarily of phytoplankton and zooplankton. Many varieties of shellfish, and crustaceans in particular, are actually closely related to insects and arachnids; crustaceans make up one of the main Subphylum, subphyla of the phylum Arthropoda. Molluscs include cephalopods (squids, octopuses, cuttlefish) and bivalves (clams, oysters), as well as gastropods (aquatic spe ...

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Operculum (fish)
The operculum is a series of bones found in bony fish and chimaeras that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding. Anatomy The opercular series contains four bone segments known as the preoperculum, suboperculum, interoperculum and operculum. The preoperculum is a crescent-shaped structure that has a series of ridges directed posterodorsally to the organism’s canal pores. The preoperculum can be located through an exposed condyle that is present immediately under its ventral margin; it also borders the operculum, suboperculum, and interoperculum posteriorly. The suboperculum is rectangular in shape in most bony fish and is located ventral to the preoperculum and operculum components. It is the thinnest bone segment out of the opercular series and is located directly above the gills. The interoperculum is triangular shaped and borders the suboperculum posterodorsally and the preoperculum anterodo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
