Lake Sava
Ada Ciganlija ( sr-cyr, Ада Циганлија, ), colloquially shortened to Ada, is a river island that has artificially been turned into a peninsula, located in the Sava River's course through central Belgrade, Serbia. The name can also refer to the adjoining artificial Lake Sava and its beach. To take advantage of its central location, over the past few decades, it was turned into an immensely popular recreational zone, most notable for its beaches and sports facilities, which, during summer seasons, can have over 100,000 visitors daily and up to 300,000 visitors over the weekend. Owing to this popularity, Ada Ciganlija has been commonly nicknamed "More Beograda" ("Belgrade's Sea"), which was officially accepted as an advertising slogan in 2008, stylised as ''More BeogrADA''. Location Ada Ciganlija is located on the southern bank of the Sava River, 4 km away from its mouth, and entirely belongs to Belgrade's municipality of Čukarica. Its eastern tip roughly bor ...

Microclimate
A microclimate (or micro-climate) is a local set of atmospheric conditions that differ from those in the surrounding areas, often with a slight difference but sometimes with a substantial one. The term may refer to areas as small as a few square meters or square feet (for example a garden bed or a cave) or as large as many square kilometers or square miles. Because climate is statistical, which implies spatial and temporal variation of the mean values of the describing parameters, within a region there can occur and persist over time sets of statistically distinct conditions, that is, microclimates. Microclimates can be found in most places but are most pronounced in topographically dynamic zones such as mountainous areas, islands, coastal areas. Microclimates exist, for example, near bodies of water which may cool the local atmosphere, or in heavy urban areas where brick, concrete, and asphalt absorb the sun's energy, heat up, and re-radiate that heat to the ambient air: t ...

Common Bream
The common bream, freshwater bream, bream, bronze bream, carp bream or sweaty bream (''Abramis brama''), is a European species of freshwater fish in the family Cyprinidae. It is now considered to be the only species in the genus ''Abramis''. Range and habitat The common bream's home range is Europe north of the Alps and Pyrenees, as well as the Balkans. They are found as far east as the Caspian Sea, the Black Sea, and the Aral Sea. The common bream lives in ponds, lakes, canals, and slow-flowing rivers. Description The bream is usually long, though some specimens of have been recorded; it usually weighs . Its maximum length is 90 cm (35.5 in),the recorded weight is around 9.1 kg (20 lb). The common bream has a laterally flattened and high-backed body and a slightly undershot mouth. It is a silvery grey colour, though older fish can be bronze-coloured, especially in clear waters. The fins are greyish to black, but never reddish. Similar-looking fish Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zander
The zander (''Sander lucioperca''), sander or pikeperch, is a species of ray-finned fish from the family Percidae, which includes the perches, ruffes and darters. It is found in freshwater and brackish habitats in western Eurasia. It is a popular game fish and has been introduced to a variety of localities outside its native range. It is the type species of the genus ''Sander''. Taxonomy The zander was first formally described in 1758 as ''Perca lucioperca'' by Carolus Linnaeus in volume 1 of the tenth edition of ''Systema Naturae'' and he gave the type locality as "European lakes". When Lorenz Oken (1779-1851) created the genus ''Sander'' he made ''Perca lucioperca'' its type species. The zander is part of the European clade within the genus ''Sander'' which split from a common ancestor with the North American clade, which the walleye (''S. vitreus'') and the sauger (''S. canadensis'') belong to, around 20.8 million years ago. Within the European clade the Volga pikeperch ('' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Pike
The northern pike (''Esox lucius'') is a species of carnivorous fish of the genus '' Esox'' (the pikes). They are typical of brackish and fresh waters of the Northern Hemisphere (''i.e.'' holarctic in distribution). They are known simply as a pike in Britain, Ireland, and most of Eastern Europe, Canada and the United States. Pike can grow to a relatively large size: the average length is about , with maximum recorded lengths of up to and published weights of . The IGFA currently recognizes a pike caught by Lothar Louis on Greffern Lake, Germany, on 16 October 1986, as the all-tackle world-record northern pike. Northern pike grow to larger sizes in Eurasia than in North America, and typically grow to larger sizes in coastal than inland regions of Eurasia. Etymology The northern pike gets its common name from its resemblance to the pole-weapon known as the pike (from the Middle English for 'pointed'). Various other unofficial trivial names are common pike, Lakes pike, great n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carp
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swim bl ...

Wels Catfish
The wels catfish ( or ; ''Silurus glanis''), also called sheatfish or just wels, is a large species of catfish native to wide areas of central, southern, and eastern Europe, in the basins of the Baltic, Black and Caspian Seas. It has been introduced to Western Europe as a prized sport fish and is now found from the United Kingdom east to Kazakhstan and China and south to Greece and Turkey. It is a freshwater fish recognizable by its broad, flat head and wide mouth. Wels catfish can live for at least fifty years. Etymology The English common name comes from Wels, the common name of the species in German language. ''Wels'' is a variation of Old High German ''wal'', from Proto-Germanic ''*hwalaz'' – the same source as for ''whale'' – from Proto-Indo-European ''*(s)kʷálos'' ('sheatfish'). Description The wels catfish's mouth contains lines of numerous small teeth, two long barbels on the upper jaw and four shorter barbels on the lower jaw. It has a long anal fin that extends t ...

Grass Carp
The grass carp (''Ctenopharyngodon idella'') is a species of large herbivorous freshwater fish in the family Cyprinidae, native to the Pacific Far East, with a native range stretching from northern Vietnam to the Amur River on the Sino-Russian border.Mandrak and Cudmore. 2004''Biological Synopsis of Grass Carp (Ctenopharyngodon idella)''. This Asian carp is the only species of the genus ''Ctenopharyngodon''. Grass carp are resident fish of large turbid rivers and associated floodplain lakes/wetlands with a wide range of temperature tolerance, and spawn at temperatures of . It is cultivated as a food fish in China for centuries, but was introduced in Europe and the United States for aquatic weed control, becoming the fish species with the largest reported farmed production globally, over five million tonnes per year.

Silver Carp
The silver carp (''Hypophthalmichthys molitrix'') is a species of freshwater cyprinid fish, a variety of Asian carp native to China and eastern Siberia, from the Amur River drainage in the north to the Xi Jiang River drainage in the south. Although a threatened species in its natural habitat, it has long been cultivated in China. By weight, more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species. The species has also been introduced, or spread by connected waterways, to at least 88 countries around the world. The reason for importation was generally for use in aquaculture, but enhancement of wild fisheries and water quality control have also been intended on occasion. In some of these places, the species is considered invasive. The silver carp reaches a typical length of with a maximum length of and ...

Motorboat
A motorboat, speedboat or powerboat is a boat that is exclusively powered by an engine. Some motorboats are fitted with inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gearbox and the propeller in one portable unit. An inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear. Overview A motorboat has one or more engines that propel the vessel over the top of the water. Boat engines vary in shape, size, and type. Engines are installed ...

Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids ( DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. Many indus ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
