Kotuy
The Kotuy () is a river in Krasnoyarsk Krai, Russia. It is one of the two rivers that form the Khatanga; the other one being the Kheta. The Kotuy is long, and the area of its basin is . It freezes up in late September or early October and breaks up in late May or early June. Course The Kotuy has its source in the Putorana Mountains and flows north, cutting from the south across the western side of the Anabar Plateau. After leaving the plateau area it flows northwestwards until the confluence with the Kheta to form the Khatanga, a little distance upstream from Khatanga town.Google Earth Its main tributaries are the Moyero, the Tukalan, the Eriyechka, the Changada, and the Kotuykan, which has its source in the highest part of the Anabar Plateau. Lake Yessey is part of the river basin. See also *List of rivers of Russia Russia can be divided into a European and an Asian part. The dividing line is generally considered to be the Ural Mountains.

Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of ocean ...

Rivers Of Krasnoyarsk Krai
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podkamennaya Tunguska
The Podkamennaya Tunguska (, literally ''Tunguska under the stones''; , Ket: Ӄо’ль) also known as ''Middle Tunguska'' or ''Stony Tunguska'', is a river in Krasnoyarsk Krai, Russia. History In 1908, an asteroid impacted near the river and later became known as the Tunguska event. Hydrology The river's nutrition is mainly snow (60%); rain and groundwater nutrition account for 16 and 24%, respectively. The flood lasts from the beginning of May to the end of June, in the lower reaches until the beginning of July. From July to October, there is a summer low, interrupted by a rise in the level to 5.5 m during floods, which can be from one to four per year. The average annual water consumption at the mouth is 1587.18 m3/s, during summer floods it reaches 35,000 m3/s. Ice phenomena have been occurring since mid-October, the autumn ice drift of 7-16 days is accompanied by the formation of ice jams. The ice age is from the end of October to the middle of May. The ice drift lasts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Largest Unfragmented Rivers
This is a list of the largest river basins without fragmentation by dams in their catchments, ordered by average annual discharge. To qualify for inclusion, a river must not only have no dams on its “main” stem, but also no dams on any tributary. For this reason, major world rivers such as the Amazon, Lena, Irrawaddy, Amur, and Fraser are disqualified because of dams on tributary streams. Many of the rivers in this list have uncertain discharges. With the exception of those in Russia, streamgauges have seldom (if ever) been placed on the majority of the largest unfragmented river systems, due to the remoteness and/or ruggedness of the terrain in which they are located. Apart from the Fly which is clearly the largest, all ranks listed here are not perfectly certain, and there also exist a number of rivers in Sundaland that might qualify with reliable discharge data, such as the Kapuas.

Loach (fish)
Loaches are ray-finned fishes of the suborder Cobitoidei. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidei comprise about 107 genera divided among 9 families. Etymology The name Cobitoidei comes from the type genus, ''Cobitis'', described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. However, its origin predates modern zoological nomenclature and derives from a term used by Aristotle to refer to "small fishes that bury... like the gudgeon." Description Loaches display a wide variety of morphologies, making the group difficult to characterize as a whole using external traits. They range in adult length from the 23 mm (1 in) miniature eel-loach, '' Pangio longimanus'', to the 50 cm (20 in) imperial flower loach, '' Leptobotia elongata'', with the latter weighing up to 3 ...

Hucho Taimen
Siberian taimen (''Hucho taimen''), also known as the common taimen (), Siberian giant trout or Siberian salmon, is a species of salmon-like ray-finned fish from the genus '' Hucho'' in the family Salmonidae. These fish are found in rivers in Siberia and adjacent regions, and are harvested throughout the year. Habits and range The taimen is distributed from the Volga and Pechora River basins in the west to the Yana and Amur River basins in the east, spanning portions of Russia, Kazakhstan, Mongolia, and China. On a larger scale, this includes parts of the Caspian, Arctic, and Pacific drainages in Eurasia. In Mongolia, the taimen is found in both the Arctic and Pacific drainages, specifically the Yenisei/ Selenga, the Lena, and the Amur River Basins. The taimen lives in flowing water and is only occasionally found in lakes, usually near the mouth of a tributary. The taimen is not anadromous, but does show increased movement rates during the spawning season. The average home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coho Salmon
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon family (biology), family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon (or "silvers") and is often sold as medium red salmon. The scientific species name is based on the Russian language, Russian common name ''kizhuch'' (кижуч). Description During their ocean phase, coho salmon have silver sides and dark-blue backs with spots on their back and upper tail lobe. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and spots, with females having darker shades than males. Coho salmon average 20 to ...

Muksun
The muksun ''(Coregonus muksun)'' is a type of whitefish widespread in the Siberian Arctic waters. It is mostly found in the freshened areas of the Kara and Laptev Seas and up the major rivers, as well as in Lake Taymyr. Like all whitefishes, it is a silvery, fusiform fish. The average length of mature fish is 33 cm and weight of 1–2 kg, and it can reach a length of 75 cm and a weight of 7–8 kg. Depending on population, the muksun can live up to 16–25 years of age. It is valuable commercially as well as locally as a source of food. As food ''Muksun'' flesh is a delicacy. It is white and tender with very few bones and is one of the species used in the Arctic Siberia Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east.

Arctic Cisco
The Arctic cisco (''Coregonus autumnalis''), also known as Arctic omul (), is an anadromy, anadromous species of freshwater whitefish that inhabits the Arctic parts of Siberia especially Yenisey Gulf. It can also be found in Alaska and Canada. It has a close freshwater relative in several lakes of Ireland, known as the Coregonus pollan, pollan, alternatively regarded as conspecific with it, or as a distinct species. Taxonomy The freshwater omul of the Lake Baikal, formerly considered a subspecies ''Coregonus autumnalis migratorius'' of the Arctic cisco, has no close genetic relationship to it and is now classified as a separate species, ''Coregonus migratorius''.

Coregonus Albula
''Coregonus albula'', known as the vendace or as the European cisco, is a species of freshwater whitefish in the family Salmonidae. It is found in lakes in northern Europe, especially Finland, Latvia, Lithuania, Sweden, Russia and Estonia, and in some lakes of Norway, the United Kingdom, northern Germany, and Poland. It is also found in diluted brackish water in the Gulfs of Finland and Bothnia, both of which are in the Baltic Sea. The length of an adult is normally about . The maximum age is about ten years. The vendace is traditionally the most important target of freshwater fisheries in parts of Fennoscandia and Russia. Vendace roe is considered a delicacy, which has been granted a PDO status in the Swedish Bothnian Bay archipelago ( Kalix löjrom). Description The vendace is a slim and streamlined fish with an adipose fin - an additional small fin on the back between the dorsal fin and the tail (caudal fin) which is typical in the salmon family.

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...
