Lake Bosten
Bosten Lake (, Uyghur: / / ''Baghrash Köli / Baƣrax Kɵli'', Chagatai: ''Bostang'') is a freshwater lake on the northeastern rim of the Tarim Basin, about east of Yanqi and northeast of Korla, Xinjiang, China in the Bayin'gholin Mongol Autonomous Prefecture. Covering an area of about (together with adjacent small lakes), it is the largest lake in Xinjiang and one of the largest inland freshwater lakes in China. Bosten lake receives water inflow from a catchment area of . The lake's Uyghur and Chinese names are sometimes rendered as ''Bosten Hu'', ''Bagrax-hu'', ''Bagrasch-köl'', ''Baghrasch köl'', ''Bagratsch-kul'', ''Bositeng Lake'' or ''Bositeng Hu.'' The Kaidu River is the most important tributary to Lake Bosten, accounting for about 83% of its water inflow, other significant tributaries are the Huangshui Ditch (), the Qingshui River (), and Wulasite River (). An active fishery exists on the lake. Until the early 1970s, two cyprinid species, '' Schizothorax biddul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yarkand River
The Yarkand River (or Yarkent River, Yeh-erh-ch'iang Ho) is a river in the Xinjiang Uyghur Autonomous Region of western China. It originates in the Siachen Muztagh in a part of the Karakoram range and flows into the Tarim River or Neinejoung River, with which it is sometimes identified. However, in modern times, the Yarkand river drains into the Midstream Reservoir and exhausts its supply without reaching the Tarim river. The Yarkand River is approximately in length, with an average discharge of . A part of the river valley is known to the Kyrgyz people as Raskam Valley, and the upper course of the river itself is called the Raskam River. Another name of the river is Zarafshan. The area was once claimed by the ruler of Hunza. Course The river originates from the Siachen Muztagh in the Karakoram range in India–Sinkiang border region, south of the Kashgar Prefecture.

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] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crucian Carp
The crucian carp (''Carassius carassius'') is a medium-sized member of the common carp family Cyprinidae. It occurs widely in northern European regions. Its name derives from the Low German ''karusse'' or ''karutze'', possibly from Medieval Latin ''coracinus'' (a kind of river fish). Distribution The crucian carp is a widely distributed European species, its range spanning from England to Russia; it is found as far north as the Arctic Circle in the Scandinavian countries, and as far south as central France and the region of the Black Sea. Its habitat includes lakes, ponds, and slow-moving rivers. It has been established that the fish is native to England and not introduced. The crucian carp is a medium-sized cyprinid, typically in body length, and rarely exceeds in weight over , but a maximum total length of has been reported for a male,Koli, L. 1990 Suomen kalat. ishes of Finland Werner Söderström Osakeyhtiö.

Common Carp
The Eurasian carp or European carp (''Cyprinus carpio''), widely known as the common carp, is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia.Fishbase''Cyprinus carpio'' Linnaeus, 1758/ref>Arkive The native wild populations are considered vulnerable to extinction by the International Union for Conservation of Nature (IUCN), but the species has also been domesticated and introduced (see aquaculture) into environments worldwide, and is often considered a destructive invasive species, being included in the list of the world's 100 worst invasive species. It gives its name to the carp family, Cyprinidae. Taxonomy The two subspecies are: * ''Cyprinus carpio carpio'', native to much of Europe (notably the Danube and Volga rivers)Jian Feng Zhou, Qing Jiang Wu, Yu Zhen Ye & Jin Gou Tong (2003).

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 ...

Black Carp
The black carp (''Mylopharyngodon piceus'') or Chinese black roach is a species of cyprinid freshwater fish and the sole extant species of the genus ''Mylopharyngodon''. It is native to lakes and rivers in East Asia, ranging from the Amur Basin across China to Vietnam. One of the largest cyprinids in the world, the black carp has a typical length of , though it can reach up to in length and in weight. It is carnivorous and generally feeds on invertebrates such as snails, clams and mussels. Black carp, together with bighead carp, silver carp, and grass carp, make up the culturally important " four famous domestic fishes" used in polyculture in China for over a thousand years. It has also been introduced in the United States as one of the invasive " Asian carps", though it is not as widely distributed worldwide as the other three. In China, black carp is widely cultivated for food and Chinese medicine, being one of the most highly esteemed and expensive domestic food fish, a ...

Bighead Carp
The bighead carp (''Hypophthalmichthys nobilis'') is a species of cyprinid freshwater fish native to East Asia, and is one of several Asian carps introduced into North America. It is one of the most intensively exploited fishes in fish farming, with an annual worldwide production of over three million tonnes in 2013, principally from China. Unlike the omnivorous common carp, bighead carp are primarily filter-feeders, preferentially consuming zooplankton but also phytoplankton and detritus. Description The bighead carp has a large, scaleless head, a large mouth, and eyes located very low on the head. Adults usually have a mottled silver-gray coloration. It is a large fish; a typical length is , and maximum observed size of and . Distribution Bighead carp are native to large rivers and are associated with floodplain lakes of eastern Asia. Their range extends from southern China north to the Amur River system, which forms the border between China and Russia. They have been i ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
