Artificial Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or larg ...

Ohře
The Ohře (), also known in English and German as Eger (), is a river in Germany and the Czech Republic, a left tributary of the Elbe River. It flows through the Bavarian district of Upper Franconia in Germany, and through the Karlovy Vary Region, Karlovy Vary and Ústí nad Labem Region, Ústí nad Labem regions in the Czech Republic. It is long, of which is in the Czech Republic, making it the List of rivers of the Czech Republic, fourth longest river in the country. Etymology The name is of Celtic language, Celtic or pre-Celtic origin. In the 9th century, it appeared as ''Agara''. According to one theory, its meaning was 'salmon river' (composed of the words ''ag'', ''eg'' – 'salmon', and ''are'', ''ara'' – 'flowing water'). Another theory suggests that the name was derived from ''agriā'' and meant a fast-moving, fast-flowing river. In the 12th century, Ohře was written as ''Egre'', ''Oegre'' and ''Ogre''. Course The Ohře originates in the territory of Weißenstadt i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruffe
The ruffe (''Gymnocephalus cernua''), also known as the Eurasian ruffe or pope, is a freshwater fish found in temperate regions of Europe and northern Asia. It has been introduced into the Great Lakes of North America as an invasive species and is causing unfortunate results as it is reproducing faster than other species. Its common names are ambiguous – "ruffe" may refer to any local member of its genus '' Gymnocephalus'', which as a whole is native to Eurasia. Description The ruffe's colors and markings are similar to those of the walleye, an olive-brown to golden-brown color on its back, paler on the sides with yellowish white undersides. The ruffe can reach up to in length, but is usually around half that size. It is a very aggressive fish for its size. The ruffe also has a large, spiny dorsal fin which is likely distasteful to its predators. It also has two fins on top, the front fin has hard and sharp spines, the back fin has soft spines called rays. The most obviou ...

Common Rudd
The common rudd (''Scardinius erythrophthalmus'') is a benthos, bentho-pelagic freshwater Actinopterygii, ray-finned fish belonging to the Family (biology), family Leuciscidae. This species is widely spread in Europe and central Asia, around the basins of the North Sea, North, Baltic Sea, Baltic, Black Sea, Black, Caspian Sea, Caspian and Aral Sea, Aral seas. Identification Morphologically, this species is very similar to the roach (''Rutilus rutilus''), with which it can be easily confused. It can be identified by the yellow eye colour. The eye of the roach has a big red spot above the pupil, that can be more or less conspicuous. The rudd has an upturned mouth allowing it to feed easily at the top of the water. The placement of the dorsal fin is more to the rear which is even visible in very young fish. There are normally only one or two scales between the tip of the pelvic fins and the anal fins, while on the roach there are five. Also the skin of the rudd is yellowish green, w ...

Common Roach
The roach, or rutilus roach (''Rutilus rutilus''), also known as the common roach, is a fresh- and brackish-water fish of the family Cyprinidae, native to most of Europe and western Asia. Fish called roach can be any species of the genera ''Rutilus'', '' Leucos'' and ''Hesperoleucus'', depending on locality. The plural of the term is also roach. Description The roach is a small fish, often reaching no more than about ; maximum length is . Its body has a bluish-silvery colour and becomes white at the belly. The fins are red. The number of scales along the lateral line is 39–48. The dorsal and anal fins have 12–14 rays. Young specimens have a slender build; older specimens acquire a higher and broader body shape. The roach can often be recognized by the big red spot in the iris above and beside the pupil. Colours of the eye and fins can be very pale, however, in some environments. In Central and Northern Europe, the common roach can most easily be confused with the common ... [...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'' (pikes). They are commonly found in brackish water, moderately salty and fresh waters of the Northern Hemisphere (''i.e.'' holarctic in distribution). They are known simply as a pike (Plural, : pike) in Great Britain, Ireland, most of Eastern Europe, Canada and the United States, U.S., although in the Midwestern United States, they may just be called a Northern. Pike can grow to a relatively large size. Their average length is about , with maximum recorded lengths of up to and maximum weights of . The International Game Fish Association, IGFA currently recognises a pike caught by Lothar Louis on Greffern Lake, Germany, on 16 October 1986, as the all-tackle world-record holding northern pike. Northern pike grow to larger sizes in Eurasia than in North America, and in coastal Eurasian regions than inland ones. Etymology The northern pike gets its common name from its resemblance to the ...

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. 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'). Evolution The earliest known fossil remains of the wels catfish are from the late Miocene (about 5.3 million years ago) of Ukraine. Potentially slightly older but less well-preserved remains from 6-7 million years ago are also known from the same region. During this time period, the dominant catfish in eastern ...

Tench
The tench or doctor fish (''Tinca tinca'') is a freshwater, fresh- and brackish water, brackish-water fish of the order Cypriniformes found throughout Eurasia from Western Europe including Great Britain, Britain and Ireland east into Asia as far as the Ob River, Ob and Yenisei Rivers. It is also found in Lake Baikal. It normally inhabits slow-moving freshwater habitats, particularly lakes and lowland rivers.B. Whitton (1982). ''Rivers, Lakes and Marshes'' p 163. Hodder & Staughton, London. Taxonomy The tench was first formally Species description, described in as ''Cyprinus tinca'' by Carl Linnaeus in 1758 in the 10th edition of Systema Naturae with its Type locality (biology), type locality given as "European lakes". In 1764 François Alexandre Pierre de Garsault proposed the new monospecific genus ''Tinca'', with ''Cyprinus tinca'' as the type species by absolute tautonymy. The 5th edition of ''Fishes of the World'' classified ''Tinca'' in the subfamily Tincinae, alongside th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Perch
The European perch (''Perca fluviatilis''), also known as the common perch, redfin perch, big-scaled redfin, English perch, Euro perch, Eurasian perch, Eurasian river perch, Hatch, poor man's rockfish or in Anglophone parts of Europe, simply the perch, is a predatory freshwater fish native to Europe and North Asia. It is the type species of the genus '' Perca''. The perch is a popular game fish for recreational anglers, and has been widely introduced beyond its native Eurasian habitats into Australia, New Zealand and South Africa. Known locally simply as "redfin", they have caused substantial damage to native fish populations in Australia and have been proclaimed a noxious species in New South Wales. Taxonomy The first scientific description of the river perch was made by Peter Artedi in 1730. He defined the basic morphological signs of this species after studying perch from Swedish lakes. Artedi described its features, counting the fin rays scales and vertebrae of the typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coregonus Maraena
''Coregonus maraena'', referred to in English as the maraene, maraena whitefish, vendace, cisco, lake herring, lake whitefish or the whitefish, is a whitefish of the family Salmonidae that occurs in the Baltic Sea basin – in the sea itself and the inflowing rivers, and in several lakes as landlocked populations. It is found in Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Netherlands, Norway, Poland, Slovakia (Štrbské pleso), Russia and Sweden. Up to 2023, it was listed as a vulnerable species by the IUCN, but this is now revised to Least Concern. It is listed as endangered by HELCOM. It is an extremely important fish within the Baltic Sea ecosystem, both for population equilibrium and for the local diets of the surrounding human population. Due to a variety of factors, mostly overfishing, the maraena's population dwindled to near-extinction levels. Thus, rampant repopulation was enacted to preserve this important fish. In the Baltic basin countries, this species h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czech Koruna
The koruna, or crown (sign: Kč; code: CZK, ), has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's eight currencies, and the Czech Republic is legally bound to adopt the euro in the future. The official name in Czech is (plural , though the zero-suffixed genitive plural form is used on banknotes and coins of value 5 Kč or higher). The ISO 4217 code is CZK and the local acronym is Kč, which is placed after the numeric value (e.g., "50 Kč") or sometimes before it (as is seen on the 10-koruna coin). One crown is made up of 100 '' hellers'' (abbreviated as "h", official name in Czech: singular: , nominative plural: , genitive plural: – used with numbers higher or equal to 5 – e.g. ), but hellers have now been withdrawn from circulation, and the smallest unit of physical currency is 1 Kč. History In 1892, the Austro-Hungarian krone replaced the gulden at the rate of two kronen to one gulden (which is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
