Sand Smelt
The sand smelt (''Atherina presbyter'') is a species of marine fish of the family Atherinidae, common in the northeastern Atlantic from the Danish straits, where it is rare, and Scotland to the Canary Islands and the western Mediterranean Sea. Sand smelt are small, pelagic fishes which are found in coastal areas and in estuaries. They are a schooling species which undertake seasonal migrations in the Atlantic. They are carnivorous and prey on small crustaceans and fish larvae. Reproduction takes place in the spring and summer, in the North Sea and the English Channel spawning takes place over midsummer. Sand smelt generally live in semi-isolated populations around river estuaries. A population living around the entrance to Southampton water was found to spawn in the April–June period within inshore algae beds before moving out into the deeper waters of the Solent. The small size of the sand smelt means it often unable to escape being drawn onto screens used to remove fish and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brest, France
Brest (; ) is a port city in the Finistère department, Brittany. Located in a sheltered bay not far from the western tip of the peninsula, and the western extremity of metropolitan France, Brest is an important harbour and the second French military port after Toulon. The city is located on the western edge of continental France. With 142,722 inhabitants in a 2007 census, Brest forms Western Brittany's largest metropolitan area (with a population of 300,300 in total), ranking third behind only Nantes and Rennes in the whole of historic Brittany, and the 19th most populous city in France; moreover, Brest provides services to the one million inhabitants of Western Brittany. Although Brest is by far the largest city in Finistère, the ''préfecture'' (regional capital) of the department is the much smaller Quimper. During the Middle Ages, the history of Brest was the history of its castle. Then Richelieu made it a military harbour in 1631. Brest grew around its arsenal unti ...

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 ...

Fish Of Europe
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, 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 vertebrate, 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 placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fawley Power Station
Fawley Power Station was an oil-fired power station located on the western side of Southampton Water, between the villages of Fawley and Calshot in Hampshire, England. Its chimney was a prominent (and navigationally useful) landmark, but it was not, as is sometimes claimed, the highest point in Hampshire (which is Pilot Hill). Overview The station, which in its final years was owned and operated by Npower, was oil-fired, powered by heavy fuel oil. Pipelines connected the station to the nearby Fawley oil refinery. There were two 10-inch (25 cm) diameter, 3.2 km long, pipelines which discharged into storage tanks with a capacity of 24,000 tonnes. Because oil is more expensive than other fuels such as coal and natural gas, Fawley did not operate continuously, but came on line at times of high demand. It was also connected to the National Grid with circuits going to Nursling and a tunnel under Southampton Water to Chilling then to Lovedean with a local substation at ...

Solent
The Solent ( ) is a strait between the Isle of Wight and Great Britain. It is about long and varies in width between , although the Hurst Spit which projects into the Solent narrows the sea crossing between Hurst Castle and Colwell Bay to just over . The Solent is a major shipping lane for passenger, freight and military vessels. It is an important recreational area for water sports, particularly yachting, hosting the Cowes Week sailing event annually. It is sheltered by the Isle of Wight and has a complex tidal pattern, which has benefited Southampton's success as a port, providing a "double high tide" that extends the tidal window during which deep-draught ships can be handled. Portsmouth lies on its shores. Spithead, an area off Gilkicker Point near Gosport, is known as the place where the Royal Navy is traditionally reviewed by the monarch of the day. The area is of great ecological and landscape importance, particularly because of the coastal and estuarine habitats a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southampton Water
Southampton Water is a tidal estuary north of the Solent and the Isle of Wight in England. The city of Southampton lies at its most northerly point, where the estuaries of the River Test and River Itchen meet. Along its salt marsh-fringed western shores lie the New Forest villages of Dibden, Hythe and Fawley, and the Fawley Refinery. On the slightly steeper eastern shore are the Southampton suburb of Weston, the villages of Netley and Hamble-le-Rice, and the Royal Victoria Country Park. To the south, Southampton Water enters the Solent between Calshot Spit and Hill Head. Southampton Water is an estuary with major potential for land use conflicts. An area of urban development (the Waterside) runs in the narrow band of land between Southampton Water and the New Forest National Park. Villages such as Marchwood, Hythe, Dibden Purlieu, Holbury and Fawley have all experienced significant growth. Geography Geographically, Southampton Water is classified as a ria, or drowned valle ...
