Neosalanx Tangkahkeii
''Neosalanx tangkahkeii'', the Chinese icefish or short-snout icefish, is a species of icefish endemic to fresh and brackish waters in China. Despite its common name it is not the only icefish in China; the majority of the species in this family are found in the country. ''Neosalanx tangkahkeii'' is widely fished. In addition to being eaten in Asia, it is exported to southern Europe as a replacement of the more expensive transparent goby, a Mediterranean species used in the local cuisine. This replacement is often done openly, but sometimes it is done fraudulently. Appearance ''Neosalanx tangkahkeii'' reached up to in standard length. They have a smooth, scale-less body, except the male has a thin line of scales at the tail base. The body is a white opaque color and the head is transparent. Conservation status ''Neosalanx tangkahkeii'' is a widespread species and among others found in the Yangtze and Yellow River basins. In some parts of its range it is a relatively low-dens ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Endemic Fauna Of China
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] |
Neosalanx
''Neosalanx'' is a genus of icefishes native to Eastern Asia, ranging from Korea, through Japan and China, to Vietnam. They inhabit coastal marine waters, estuaries and river basins (including lakes). There are both species that are threatened and species that are widespread. They are up to in standard length. Despite their small size they are important food fish, and for this reason there have been attempts of introducing ''N. pseudotaihuensis'', ''N. taihuensis'' and ''N. tangkahkeii'' to parts of China where not naturally found. Most of these attempted introductions failed, but some were successful and in these places they are now often the most common fish. Feeding on planktonic crustaceans and tiny fish, they have outcompeted certain native fish like ''Anabarilius grahami'', which have become rare and threatened. Species Fishbase currently recognizes 10 species in this genus, though ''N. taihuensis'' was found to be invalid during the DNA sequencing: * ''Neosalanx anders ...

Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...

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] |
Protosalanx
''Protosalanx'' is a small genus of icefishes that are native to China, Korea and Vietnam where they primarily inhabit coastal waters and nearby fresh waters. They are commercially fished and used for aquaculture in China, where also introduced to some inland waters like Lake Dianchi. In addition to being eaten locally in Asia, they are exported to southern Europe as a replacement of the more expensive transparent goby, a Mediterranean species used in the local cuisine. This replacement is often done openly, but sometimes it is done fraudulently. ''Protosalanx'' are up to in standard length, have a transparent body and largely lack scales. They are open-water fish. Small ''Protosalanx'' mostly feed on zooplankton, but larger individuals also take small fish, including cannibalism of young of their own species. They are naturally anadromous, with adults migrating from their coastal sea habitat into estuaries to spawn and the juveniles returning to the coastal sea. However, some ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overfishing
Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area. Overfishing can occur in water bodies of any sizes, such as ponds, wetlands, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass levels. Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the overfishing of sharks, has led to the upset of entire marine ecosystems. Types of overfishing include: growth overfishing, recruitment overfishing, ecosystem overfishing. The ability of a fishery to recover from overfishing depends on whether its overall carrying capacity and the variety of ecological conditions are suitable for t ...
