Mjörn (lake)
Mjörn is a lake in Västergötland, shared between the municipalities of Alingsås and Lerum and is part of the main catchment area of the Göta River. The lake is 48 meters deep, covers an area of 54.5 square kilometers and has an elevation of 57.1 meters above sea level. About the lake Mjörn is 55 km2 in size and has a maximum depth of 48 meters. It is 16 km long and 7 km wide. This makes it the second largest lake in Västergötland that lies entirely within the landscape (after Unden). The lake is 58 m above sea level. There are around 60 named islands in Mjörn. Alingsås and Västra Bodarna lie on the lake's eastern shore and Sjövik and Björboholm on the western shore. The lake is not fully regulated, so the water level can vary quite considerably. Its ice and winds are also quite unpredictable. Mjörn is drained by Säveån. Its tributaries include Lake Anten and Lake Ålandasjön in the north and Säveån through Alingsås. Its outflow is mainly in ...

Västergötland
Västergötland (), also known as West Gothland or the Latinized version Westrogothia in older literature, is one of the 25 traditional non-administrative provinces of Sweden (''landskap'' in Swedish), situated in the southwest of Sweden. Västergötland is home to Gothenburg, the second largest city in Sweden, which is situated along a short stretch of the Kattegat strait. The province is bordered by Bohuslän, Dalsland, Värmland, Närke, Östergötland, Småland and Halland, as well as the two largest Swedish lakes Vänern and Vättern. Victoria, Crown Princess of Sweden is Duchess of Västergötland. Administration The provinces of Sweden serve no administrative function. Instead, that function is served by counties of Sweden. From the 17th century up until 31 December 1997, Västergötland was divided into Skaraborg County, Älvsborg County and a minor part of Gothenburg and Bohus County. From 1 January 1998 nearly all of the province is in the newly created Väs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Little Ringed Plover
The little ringed plover (''Charadrius dubius'') is a small plover. The genus name ''Charadrius'' is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek ''kharadrios'' a bird found in river valleys (''kharadra'', "ravine"). The specific ''dubius'' is Latin for doubtful, since Sonnerat, writing in 1776, thought this bird might be just a variant of common ringed plover. Description Adult little ringed plovers have a grey-brown back and wings, a white belly and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes with white above and a short dark bill. The legs are flesh-coloured and the toes are all webbed. This species differs from the larger ringed plover in leg colour, the head pattern, and the presence of a clear yellow eye-ring.

Osprey
The osprey (; ''Pandion haliaetus''), historically known as sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than in length and a wingspan of . It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and unique behaviour in hunting its prey. Because of its unique characteristics it is classified in its own taxonomic genus, ''Pandion'', and family, Pandionidae. Taxonomy The osprey was described in 1758 by the Swedish naturalist Carl Linnaeus under the name ''Falco haliaetus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-throated Loon
The black-throated loon (''Gavia arctica''), also known as the Arctic loon and the black-throated diver, is a migratory aquatic bird found in the northern hemisphere, primarily breeding in freshwater lakes in northern Europe and Asia. It winters along sheltered, ice-free coasts of the north-east Atlantic Ocean and the eastern and western Pacific Ocean. This loon was first described by Carl Linnaeus in 1758 and has two subspecies. It was previously considered to be the same species as the Pacific loon, of which it is traditionally considered to be a sister species, although this is debated. In a study that used mitochondrial and nuclear intron DNA, the black-throated loon was found to be sister to a clade consisting of the Pacific loon and two sister species, the common loon and the yellow-billed loon. The black-throated loon measures about in length and can weigh anywhere from . In breeding plumage, the adult of the nominate subspecies has mostly black upperparts, with the ...

Common Eider
The common eider (pronounced ) (''Somateria mollissima''), also called St. Cuthbert's duck or Cuddy's duck, is a large ( in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to . The eider's nest is built close to the sea and is lined with eiderdown, plucked from the female's breast. This soft and warm lining has long been harvested for filling pillows and quilts, but in more recent years has been largely replaced by down from domestic farm-geese and synthetic alternatives. Although eiderdown pillows or quilts are now a rarity—typically being marketed as luxury goods—eiderdown harvesting continues and is sustainable, as it can be done after the ducklings leave the nest with no harm to the birds. Taxonomy The common eider was for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Oystercatcher
The Eurasian oystercatcher (''Haematopus ostralegus'') also known as the common pied oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It has striking black and white plumage, a long straight orange-red bill, red eyes and relatively short dull pink legs. The sexes are similar in appearance but the bill of the female is longer than that of the male. It is the most widespread of the oystercatchers, with four subspecies breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. Taxonomy The Eurasian oystercatcher was listed by Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae'' under the binomial name ''Haemotopus ostralegus''. The genus name ''Haematopus'' combines the Ancient Greek ''haima'' αἷμα meaning "blood" and ''pous'' πούς meaning "foot". The specific epithet ''ostralegus'' combi ...

Great Black-backed Gull
The great black-backed gull (''Larus marinus'') is the largest member of the gull family. It is a very aggressive hunter, pirate, and scavenger which breeds on the coasts and islands of the North Atlantic in northern Europe and northeastern North America. Southern populations are generally sedentary, while those breeding in the far north (northern Norway, northwest Russia) move farther south in winter. A few also move inland to large lakes and reservoirs. The adult has a white head, neck and underparts, dark blackish-grey wings and back, pink legs and the bill yellow with a red spot. Taxonomy The great black-backed gull was one of the many species originally described by Carl Linnaeus in his 1758 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'', and it still bears its original name of ''Larus marinus''. The scientific name is from Latin. ''Larus'' appears to have referred to a gull or other large seabird. The specific name ''marinus'' means "marine", or when t ...

Fishing License
A fishing license (American English, US), fishing licence (British English, UK), or fishing permit is an administrative or legal mechanism employed by state government, state and local governments to regulate fishing activities within their administrative areas. Licensing is one type of fisheries management commonly used in Western countries, and may be required for either commercial fishing, commercial or recreational fishing. Historical licensing In 1765, the Chinese Qing dynasty government required all fishing boat operators to obtain a fishing license under the ''aojia'' system that regulated coastal populations. The Tanka people, Dan boat people of Guangdong had to acquire a fishing license as early as 1729. The wooden license issued by the government was to be displayed on the bow or stern of a boat. The information on the license consisted of the name and age of the boat's owner, the ship's status as either a fishing or commercial vessel, the home port of the boat, cre ...

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 ...

European Smelt
The Smelt or European smelt (''Osmerus eperlanus'') is a species of fish in the family Osmeridae. Appearance The body of the European smelt is typically long, slender and slightly flattened on either side. Larger fish may reach in length. Smelts have a slightly translucent body. The back and sides are grey-green to pink in colour, the flanks bright silver. The tailfin has a dark border. The smelt lives for up to six years. One characteristic is its intense smell, reminiscent of fresh cucumbers. Habitat and life The smelt is a sea fish that lives in the coastal waters of Europe from the Baltic Sea to the Bay of Biscay. A freshwater form, known in Germany as the ''Binnenstint'' ("Inland smelt"), is common in the larger lakes of Northern Europe. The smelt gather and swim about in the underflows of stronger currents in order to spawn above areas of sand. This takes place from the end of February to March, if the water temperature is above . The egg count per female can be as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coregonus Albula
''Coregonus albula'', known as the vendace or as the European cisco, is a species of freshwater whitefish in the family Salmonidae. It is found in lakes in northern Europe, especially Finland, Latvia, Lithuania, Sweden, Russia and Estonia, and in some lakes of Norway, the United Kingdom, northern Germany, and Poland. It is also found in diluted brackish water in the Gulfs of Finland and Bothnia, both of which are in the Baltic Sea. The length of an adult is normally about . The maximum age is about ten years. The vendace is traditionally the most important target of freshwater fisheries in parts of Fennoscandia and Russia. Vendace roe is considered a delicacy, which has been granted a PDO status in the Swedish Bothnian Bay archipelago ( Kalix löjrom). Description The vendace is a slim and streamlined fish with an adipose fin - an additional small fin on the back between the dorsal fin and the tail (caudal fin) which is typical in the salmon family. Its lower jaw is longer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
