Schizothorax Argentatus
The Balkhash marinka (''Schizothorax argentatus''), is a species of ray-finned fish in the genus ''Schizothorax'' of the family Cyprinidae which is found in the Lake Balkhash basins in Kazakhstan and Xinjiang. It uses gravel substrates for spawning and the unshed roe is toxic. Biology There are two distinct forms of the Blakhash marinka, a riverine form, and a faster growing migratory lacustrine form, however, both forms spawn in fast flowing currents over gravel beds. The females are sexually mature at4-11 years of age, the males at 3–8 years old. They are a fecund species and may lay between 12,000 and 122,500 eggs, although normally32,000 to 67,000 are laid in a spawning, the amount being dependent on the demographic make up of the spawning stock. Each egg is 2.3 mm in diameter. At a water temperatures ranging from 15 °C to 16 °C, and under controlled conditions, the eggs take 5 days to hatch. After six days from hatching the larval fish reach lengths of app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyprinid
Cyprinidae is a Family (biology), family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barb (fish), barbs and barbel (fish), barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate, vertebrate animal family overall, with about 1,780 species divided into 166 valid genus, genera. Cyprinids range from about 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, or ''agastric'', 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 Process (anatomy), bony process of the skull. The ...

Lake Balkhash
Lake Balkhash, also spelt Lake Balqash (, , ), is a lake in southeastern Kazakhstan, one of the largest lakes in Asia and the 15th largest in the world. It is located in the eastern part of Central Asia and sits in the Balkhash-Alakol Basin, an endorheic (closed) basin. The basin drains seven rivers, the primary of which is the Ili, bringing most of the riparian inflow; others, such as the Karatal, bring surface and subsurface flow. The Ili is fed by precipitation, largely vernal snowmelt, from the mountains of China's Xinjiang region. The lake currently covers about . However, like the Aral Sea, it is shrinking due to diversion and extraction of water from its feeders. The lake has a narrow, quite central, strait. The lake's western part is fresh water and its eastern half is saline. The eastern part is on average 1.7 times deeper than the west. The largest shore city is named Balkhash and has about 66,000 inhabitants. Main local economic activities include mining, ore p ...

Ostariophysi
Ostariophysi is the second-largest superorder of fish. Members of this superorder are called ostariophysians. This diverse group contains 10,758 species, about 28% of known fish species in the world and 68% of freshwater species, and are present on all continents except Antarctica. They have a number of common characteristics such as an alarm substance and a Weberian apparatus. Members of this group include fish important to people for food, sport, the aquarium industry, and research. Taxonomy The superorder is divided into two series, Anotophysi and Otophysi. However, in older literature, Ostariophysi was restricted only to the fish that are currently classified under Otophysi. Otophysi was coined in 1970 by Rosen and Greenwood to separate the traditional Ostariophysians from the added Gonorynchiformes. The superorder is classified below: *Series Anotophysi ** Gonorynchiformes, about 107 species *Series Otophysi (Euostariophysi) ** Cypriniformes ( minnows and allies), a ...

Karl Kessler
Karl Fedorovich Kessler (; – ) was a Baltic German zoologist who worked as a professor of biology at Saint Petersburg Imperial University. Among his contributions was the idea that evolution at an infraspecific level involved mutual aid and that Charles Darwin had placed too much emphasis on competition which he accepted as occurring at the interspecies level. Life and work Kessler was born in Damrau, Konigsberg, where his father was a royal forester (''oberforestmeister''). His father moved to Novgorod Governorate, where Kessler grew up. In 1828, he joined the with a scholarship and went to Saint Petersburg Imperial University in 1834. He attended the zoology lectures of Stepan Kutorga. After graduation he worked as a school mathematics teacher. In 1837, Kessler and his botanist friend from student days, went on an expedition to Finland. In 1840, he defended a master's dissertation on the legs of birds in relation to systematics. In 1842, his doctoral dissertation ...
