Blackspot Seabream
The blackspot seabream (''Pagellus bogaraveo''), also known as the red seabream, is a marine ray-finned fish species in family Sparidae. It is widespread in the Eastern Atlantic from Norway to Mauritania, including Macaronesia and the western Mediterranean. Description The blackspot seabream is a fish with a moderately deep body, a rounded snout and large eyes which have a diameter greater than the length of the snout. It has small sharp teeth and larger, flatter teeth set into the sides of the jaws. It has a long dorsal fin which has 12 spines in the anterior portion and 12–13 branched rays in the posterior portion. The shorter anal fin has 3 spines and 12–13 branched rays. The pectoral fins are relatively long and are pointed at their tips. The back and upper flanks are reddish in colour and the lower part of the body is silvery with a pinkish tinge. There is a black spot situated directly above the base of the pectoral fin. The maximum recorded standard length is but a m ...

Morten Thrane Brünnich
Morten Thrane Brünnich (30 September 1737 – 19 September 1827) was a Denmark, Danish zoologist and mineralogist. Biography Brünnich was born in Copenhagen, the son of a portrait Painting, painter. He studied oriental languages and theology, but soon became interested in natural history. He contributed his observations of insects to Erik Pontoppidan's ''Danske Atlas'' (1763–81). After being put in charge of the natural history collection of Christian Fleischer he became interested in ornithology, and in 1764 he published ''Ornithologia Borealis'', which included the details of many Scandinavian birds, some described for the first time. The publication of ''Ornithologia Borealis'' was aided by his insight in the collection. Brünnich corresponded with many foreign naturalists including Carl Linnaeus, Linnaeus, Peter Simon Pallas and Thomas Pennant. He published his ''Entomologia'' in 1764. He then embarked on a long tour of Europe, spending time studying the fish of the Medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous special territory of the European Union. The seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. 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. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain 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 environmental source of food and commercial product which help to improve healthier habitats and used to recon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarifa
Tarifa (, Arabic: طريفة) is a Spanish municipality in the province of Cádiz, Andalusia. Located at the southernmost end of the Iberian Peninsula, it is primarily known as one of the world's most popular destinations for windsports. Tarifa lies on the Costa de la Luz ("coast of light") and across the Strait of Gibraltar facing Morocco. Besides the city proper, the municipality also comprises several villages, including Tahivilla, Facinas, and Bolonia. History It was thought that Tarifa was once the site of the Roman settlement of Julia Transducta (also known as Julia Joza, or just Transducta). However, that settlement is now thought to have been where Algeciras now stands, while there is strong evidence that Casas de Porro, Valdevaqueros (Tarifa) was the site of the settlement of Mellaria. Tarifa was given its present name after the attack of Tarif ibn Malik in 710, a Berber military commander of Musa bin Nusayr. The village of Bolonia near Tarifa was also populated i ...

Sardine
"Sardine" and "pilchard" are common names for various species of small, oily forage fish in the herring family Clupeidae. The term "sardine" was first used in English during the early 15th century, a folk etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant. The terms "sardine" and "pilchard" are not precise, and what is meant depends on the region. The United Kingdom's Sea Fish Industry Authority, for example, classifies sardines as young pilchards. One criterion suggests fish shorter in length than are sardines, and larger fish are pilchards. The FAO/WHO Codex standard for canned sardines cites 21 species that may be classed as sardines. FishBase, a comprehensive database of information about fish, calls at least six species "pilchard", over a dozen just "sardine", and many more with the two basic names qualified by various adjectives. Etymology 'Sardine' first appeared in English in the 15th century, a loanword ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Bay Of Biscay
The Bay of Biscay (), known in Spain as the Gulf of Biscay ( es, Golfo de Vizcaya, eu, Bizkaiko Golkoa), and in France and some border regions as the Gulf of Gascony (french: Golfe de Gascogne, oc, Golf de Gasconha, br, Pleg-mor Gwaskogn), is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Point Penmarc'h to the Spanish border, and the northern coast of Spain west to Cape Ortegal.

Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and marine reptile, reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing Ovum, ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mos ...

Protoandrous Hermaphrodites
Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants. Sequential hermaphroditism occurs when the individual changes its sex at some point in its life. In particular, a sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Species that can undergo these changes from one sex to another do so as a normal event within their reproductive cycle that is usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex change in either directi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molluscs
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant taxon, extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater mollusc, freshwater and Terrestrial molluscs, terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 Taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologically advanced of all inve ...
