Sinocyclocheilus Altishoulderus
''Sinocyclocheilus altishoulderus'' (common name: high-shoulder golden-line barbel) is a species of cave fish in the family Cyprinidae. It is endemic to Guangxi province in southern China, and only known from a cave in Donglan County, from a subterranean tributary of the Hongshui River, a tributary of the Pearl River. Description ''Sinocyclocheilus altishoulderus'' grow to total length; mean length is much less, about . The eyes are small. The body is hump-backed and depigmented, semi-transparent and whitish in colour. Ecology and behaviour Ecology and behaviour of this species are unknown. It shares its habitat (and type locality) with another cave fish species, '' Sinocyclocheilus donglanensis''. Habitat and conservation The type locality, near Gongping Village, Taiping Town, Donglan County, is a subterranean river some 10–20 metres inside from the mouth of a small cave. During the rainy season, the water can extend outside the cave to form a small lake. The habitat is p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

Freshwater Fish Of China
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Sinocyclocheilus
''Sinocyclocheilus'' is a genus of freshwater fish in the family Cyprinidae endemic to China, where only found in Guangxi, Guizhou and Yunnan.Ma, L.; and Y.-H. Zhao (2012). Cavefish of China. Pp. 107—125 in: White, W.B.; and D.C. Cuvier, editors. Encyclopedia of Caves. Elsevier. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes (some are completely blind). Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back (above the forehead), the function of which is unclear. In contrast, the ''Sinocyclocheilus'' species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations ...

Cave Fish
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.Romero, Aldemaro, editor (2001). ''The Biology of Hypogean Fishes.'' Developments in Environmental Biology of Fishes. Helfman, G.S. (2007). ''Fish Conservation: A Guide to Understanding and Restoring Global Aquatic Biodiversity and Fishery Resources'', pp. 41–42. Island Press. There are more than 200 scientifically described species of obligate cavefish found on all continents, except Antarctica. Although widespread as a group, many cavefish species have very small ranges and are seriously threatened.Fenolio, D.B.; Zhao, Y.; Niemiller, M.L.; and Stout, J. (2013).

Pesticide Pollution
The environmental effects of pesticides describe the broad series of consequences of using pesticides. The unintended consequences of pesticides is one of the main drivers of the negative impact of modern industrial agriculture on the environment. Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Other agrochemicals, such as fertilizers, can also have negative effects on the environment. The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas. Other problems emerge from poor production, transport, storage and disposal practices.Tashkent (1998)P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Pearl River (China)
The Pearl River, also known by its Chinese name Zhujiang or Zhu Jiang in Mandarin pinyin or Chu Kiang and formerly often known as the , is an extensive river system in southern China. The name "Pearl River" is also often used as a catch-all for the watersheds of the Xi ("West"), Bei ("North"), and Dong ("East") rivers of Guangdong. These rivers are all considered tributaries of the Pearl River because they share a common delta, the Pearl River Delta. Measured from the farthest reaches of the Xi River, the Pearl River system is China's third-longest river, after the Yangtze River and the Yellow River, and second largest by volume, after the Yangtze. The Pearl River Basin () drains the majority of Liangguang (Guangdong and Guangxi provinces), as well as parts of Yunnan, Guizhou, Hunan and Jiangxi in China; it also drains northern parts of Vietnam's Northeast Cao Bằng and Lạng Sơn provinces. As well as referring to the system as a whole, the Pearl River (Zhu Jiang) nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hongshui River
The Hongshui River is a major river in the Guangxi Zhuang Autonomous Region in Southern China. It is one of the main rivers in the basin of the Xi River, which in its turn is one of the main tributaries of the Pearl River. Because it flows through the red rock series area, the river is reddish brown, hence the name ''Hongshui River'' (). Conventionally, the Hongshui River is formed by the merging of the Beipan and Nanpan Rivers (Beipanjiang and Nanpanjiang, i.e., the Northern and Southern Pan Rivers) at the Guizhou-Guangxi border. From there, it flows in the general southeastern direction. In Laibin Prefecture in central Guangxi the Hongshui merges with the Liu River that comes from the north, forming the Qian River, which continues to the east toward, eventually, the Xi River. The Hongshui has 10 large dams on it, that provide electric power and flood control. According to the ''Beijing Review'' the Hongshui River had 300 shoals that interfered with navigating the river wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
