The lake forms part of the Tyresån lake system and as such is considered important for recreational activities such as angling and bathing. Common fish species include perch, zander pike, lake trout, carp bream, and roach.Tyresö Municipality, ''Fiske'' Environmental impact When the water stagnates in late summer hydrogen sulfide and oxygen shortage occurs in the lake sediments. However, levels of bacteria are low and the lake is considered safe for bathing. No contamination except nutritive salt has been reported.

Barnsjön
Barnsjön (Swedish for "the Child Lake") is a small lake within the Tyresån Lake System in Tyresö Municipality south of Stockholm, Sweden. The lake, situated between the residential areas Trollbäcken and Bollmora, empties into Lake Tyresö-Flaten through the brook Prästängsdiket.Tyresåsamarbetet, ''Barnsjön'' It is regarded as an important local recreational milieu. It is popular for both fishing and bathing. There are two municipal baths by the lake.Tyresö Municipality, ''Barnsjön'' Environmental impact Barnsjön is a forest lake poor in nutrients. With a low buffering capacity, the lake is sensitive to acid deposits and has an acidity at about pH 7. It is therefore regarded as important to avoid contaminations within its catchment area.

Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...

Rutilus
''Rutilus'' is a genus of fish in the family Cyprinidae found in Eurasia. This genus is a widely distributed lineage of cyprinids and ranges from West Europe to East Siberia. Species In FishBase (2022), nine species are included in the genus: * ''Rutilus caspicus'' (Yakovlev, 1870) (Caspian roach) * ''Rutilus frisii'' ( Nordmann, 1840) (Black sea roach) * ''Rutilus heckelii'' (Nordmann, 1840) * ''Rutilus kutum'' (S. N. Kamensky, 1901) (Caspian kutum) * ''Rutilus meidingeri'' ( Heckel, 1851) * ''Rutilus pigus'' ( Lacépède, 1803) (Pigo) * '' Rutilus rutilus'' (Linnaeus, 1758) (Common roach) * ''Rutilus stoumboudae Bianco & Ketmaier, 2014 * ''Rutilus virgo'' ( Heckel, 1852) (Cactus roach) In a phylogeographic study, Levin et al. (2017) argue that the Ponto-Caspian taxa including ''R. caspicus'', ''R. heckelii'' and ''R. stoumboudae'' could represent a single widespread species whose range extends to Siberia, to be named ''Rutilus lacustris'', whereas ''R. kutum'' is included in ...

Carp 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...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] |
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] |
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 species of the freshwater perch native to Europe and northern Asia. The species is a popular quarry for anglers, and has been widely introduced beyond its native area, into Australia, New Zealand and South Africa. They have caused substantial damage to native fish populations in Australia and have been proclaimed a noxious species in New South Wales. Description European perch are greenish with red pelvic, anal and caudal fins. They have five to eight dark vertical bars on their sides. When the perch grows larger, a hump grows between its head and dorsal fin. European perch can vary greatly in size between bodies of water. They can live for up to 22 years, and older perch are often much larger than average; t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
