Cyprinid Fish Of Asia
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used ...

Schizothorax
''Schizothorax'' is a genus of cyprinid fish found in southern and western China, through northern South Asia ( Himalaya) and Central Asia, to Iran, with a single species, ''S. prophylax'', in Turkey.Yang, J.; J.X. Yang; and X.Y. Chen (2012). A re-examination of the molecular phylogeny and biogeography of the genus Schizothorax (Teleostei: Cyprinidae) through enhanced sampling, with emphasis on the species in the Yunnan–Guizhou Plateau, China. Journal of Zoological Systematics and Evolutionary Research 50(3). They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin.Coad, B.; and J. Hales (2008)Helmand - Sistan.Freshwater Ecoregions of the World. Retrieved 18 May 2019. Their scientific name means "cloven-breast", from Ancient Greek () 'to cleave' and () 'breast-plate' (see also thorax).

Schizopygopsis
''Schizopygopsis'' is a genus of cyprinid fish. Most species are endemic to river basins in the Himalayas and Qinghai–Tibet Plateau of China, but ''S. stoliczkai'' extends into the highlands of Afghanistan, Iran, northern India, Kyrgyzstan, Pakistan and Tajikistan.Delin Qi, Songchang Guo, Yan Chao, Qinghui Kong, Changzhong Li, Mingzhe Xia,Baosheng Xie and Kai Zhao (2015).

''S. younghusbandi'' is up to almost in total length, but the remaining species generally only reach about two-thirds of that size. Similar to '' Platypharodon'', ''Schizopygopsis'' have a horny sheath on the lower jaw and spoon-shaped teeth that they use to scrape off periphyton and algae from stones, but they will also eat benthic invertebrates.Tang, Y.; C.

Chuanchia
''Chuanchia labiosa'' is a species of cyprinid fish that is only found in the upper reaches of the Yellow River basin in the Qinghai–Tibet Plateau of China, where it mostly inhabits slow-flowing cold waters at altitudes above . It is the only member of its genus, but is related to other schizothoracines (snowtrout and allies) like '' Aspiorhynchus'', ''Diptychus'', ''Gymnodiptychus'', '' Gymnocypris'', '' Oxygymnocypris'', '' Platypharodon'', ''Ptychobarbus'', ''Schizopyge'', ''Schizopygopsis'' and ''Schizothorax''.Tang, Y.; C.

Oxygymnocypris
''Oxygymnocypris stewartii'' is a species of cyprinid fish endemic to Tibet and occurs in the Yarlung Tsangpo River (=upper Brahmaputra) and its tributaries at altitudes above in the Qinghai-Tibet Plateau. It is the only species in its genus. Life history and ecology ''Oxygymnocypris stewartii'' grows to in standard length, in total length and in weight. It is a long-lived (to 25 years), late-maturing species that reproduces annually. ''Oxygymnocypris stewartii'' inhabits the deeper areas of clear, fast-flowing rivers with a rocky substrate. It is a generalized and opportunistic predator feeding both on fish and aquatic insects. Smaller specimens feed mostly on cobitid nemacheilid loaches and caddisflies of family Hydropsychidae, whereas larger individuals switch more towards cyprinid fishes and chironomid The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution.

Alexander Mikhailovich Nikolsky
Alexander Mikhailovich Nikolsky (Russian: Александр Михайлович Никольский; February 18, 1858 – December 8, 1942) was a Russian and Ukrainian zoologist born in Astrakhan. From 1877 to 1881, he studied at the University of St. Petersburg, earning his doctorate several years later in 1887. From 1881 to 1891, he took part in numerous expeditions to Siberia, the Caucasus, Persia, Japan, et al. In 1887 he became an associate professor in St. Petersburg, later becoming director of the herpetology department at the Zoological Museum of the Academy of Sciences (1895). In 1903 he relocated as a professor to the Kharkiv University. In 1919 he was elected a member at the Academy of Sciences of Ukraine. Among his written works were ''Herpetologia Caucasica'' (1913), and volumes on reptiles and amphibians that were part of the series "Fauna of Russia and Adjacent Countries". He is the taxonomic authority of 26 reptile species. The viper '' Vipera nikolski ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
