European seabass
The European seabass (Dicentrarchus labrax), also known as the branzino, European bass, sea bass, common bass, white bass, capemouth, white salmon, white mullet, sea dace or loup de mer, 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 and late autumn. 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 seabass is a slow-growing species that takes several years to reach adulthood. An adult European seabass usually weighs around 2.5 kg (5 lb 8 oz). European seabass can reach measurements of up to 1 m (3 ft 3 in) in length and 12 kg (26 lb) in weight, though the most common size is only about half of that at 0.5 m (1 ft 8 in). [citation needed] Individuals are silvery grey and sometimes a dark-bluish color on the back.
Juveniles form schools and feed on invertebrates, while adults are less social and prefer to consume other fish. They are generally found in the littoral zone near the banks of rivers, lagoons, and estuaries during the summer and migrate offshore during the winter. European sea bass feed on prawns, crabs and small fish. It is a sought-after gamefish and is listed as Near Threatened by the International Union for Conservation of Nature due to a decreasing population.
The European seabass was first described in 1758 by Swedish zoologist Carl Linnaeus in his work Systema Naturae. He named it Perca labrax. In the century and a half following, it was classified under a variety of new synonyms, with Dicentrarchus labrax winning out as the accepted name in 1987. Its generic name, Dicentrarchus, derives from Greek, from the presence of two anal spines, "di" meaning two, "kentron" meaning sting, and "archos" meaning anus. The European bass is sold under dozens of common names in various languages. In the British Isles, it is known as the "European bass," "European seabass," "common bass," "capemouth," "king of the mullets," "sea bass," "sea dace," "sea perch," "white mullet," "white salmon," or simply "bass".
There are two genetically distinct populations of wild European seabass. The first is found in the northeast Atlantic Ocean, and the second is in the western Mediterranean Sea. The two populations are separated by a relatively narrow distance in a region known as the Almeria-Oran oceanographic front, located east of the Spanish city of Almería. The exact reason for this separation is unknown, as the geographic divide should not account for the lack of gene flow between the two populations. The larval stage of the European seabass can last up to three months, during which it cannot swim well, and even a small amount of water flow should transport some individuals between the two regions. In addition, juveniles can survive temperature and salinity changes, and adults can migrate hundreds of kilometres.
European seabass habitats include estuaries, lagoons, coastal waters, and rivers. It is found in a large part of the eastern Atlantic Ocean, from southern Norway to Senegal. It can also be found in the entire Mediterranean Sea and in the southern Black Sea but is absent from the Baltic Sea. It has entered the Red Sea through the Suez Canal as an anti-Lessepsian migrant. It is a seasonally migratory species, moving further winter spawning grounds during at least one month before moving towards their summer feeding areas.
The European seabass hunts as much during the day as it does at night, feeding on small fish (both pelagic, such as sardines, sprats, and sand smelts, and demersal, such as sand eels), polychaetes, cephalopods (such as squid), and crustaceans. The big fish weighing more than 4 kg (9 lb) are mostly night hunters. They spawn from February to June, mostly in inshore waters. As fry they are pelagic, but as they develop, they move into estuaries, where they stay for a year or two.
