Least Cisco
''Coregonus sardinella'', known as the least cisco or the sardine cisco, is a fresh- and brackishwater salmonid fish that inhabits rivers, estuaries and coastal waters of the marginal seas of the Arctic Basin, as well as some large lakes of those areas. In North America it is found from the Murchison River (Nunavut) west through the Bering Strait to the Bristol Bay (Bering Sea) in Alaska, and in the Russian Arctic from the northern part of the Bering Sea across the Siberian Arctic coast to the Kara Sea and Kara River and further to the Pechora River drainage on the European side. Sendek DS (2021Phylogenetic relationships in vendace and least cisco, and their distribution areas in western Eurasia.''Annales Zoologici Fennici'' 58: 289–306.

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoology, zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "''Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kara River
The Kara () is a river draining to the Arctic Kara Sea in Russia. It flows through the Pai-Khoi Range in the Polar Ural region, and forms parts of the borders between the Yamalo-Nenets Autonomous Okrug, the Nenets Autonomous Okrug and the Komi Republic. The length of the river, from the confluence of the Malaya and Bolshaya Kara to the mouth in the Baydaratskaya Bay is . Its drainage basin area is . The settlement of Ust-Kara is near the river mouth. The name of the river is derived from Nenets The Nenets (; ), in the past also called 'Samoyeds' or 'Yuraks', are a Samoyedic ethnic group native to Arctic Russia, Russian Far North.

Freshwater Fish Of The Arctic
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but 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. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always pota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peled (fish)
The peled (''Coregonus peled''), also called the ''northern whitefish'', is a species of freshwater whitefish in the family Salmonidae. It is found in northern Europe and Asia. The peled is related to ciscoes of the ''Coregonus sardinella'' complex.Politov DV, Bickham JW, Patton JC (2004 Molecular phylogeography of Palearctic and Nearctic ciscoes ''Ann. Zool. Fennici'' 41:13-23. Description Smaller peled much resemble slim vendace or whitefish but as they grow larger they develop a deeper body which becomes less tapered and more blocky. The jaws are of equal length which is in contrast to the whitefish which has a snout longer than its lower jaw, and the vendace which has a projecting lower jaw. Another distinction is that the first gill arch has 50–65 gill rakers, a larger number than either of the other species. This fish grows to a length of about and a maximum weight of . It has a dark back, silvery flanks and white belly. Distribution and habitat The peled is native to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Its lower jaw is longer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pechora River
The Pechora (; Komi: Печӧра; Nenets: Санэроˮ яха) is the sixth-longest river in Europe. Flowing from Northwest Russia and into the Arctic Ocean, it lies mostly in the Komi Republic but the northernmost part crosses the Nenets Autonomous Okrug. Geography The Pechora is long (a little shorter than the Columbia River) and its basin is , or about the same size as Finland. By mean annual discharge it ranks third in Europe, after the Volga and Danube. Its discharge is about three quarters that of the Danube and a little more than its sister, the Northern Dvina, and is the largest of any river with no dams in its basin outside of New Guinea. West of its lower course is the Timan Ridge. East of the basin along the west flank of the Urals is the Yugyd Va National Park. Also in the basin is the Virgin Komi Forests, the largest virgin forest in Europe. In the far northeast of the basin on the Usa River is the large coal center of Vorkuta. The river was once an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kara Sea
The Kara Sea is a marginal sea, separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya, and from the Laptev Sea to the east by the Severnaya Zemlya archipelago. Ultimately the Kara, Barents and Laptev Seas are all extensions of the Arctic Ocean north of Siberia. The Kara Sea's northern limit is marked geographically by a line running from Cape Kohlsaat in Graham Bell Island, Franz Josef Land, to Cape Molotov (Arctic Cape), the northernmost point of Komsomolets Island in Severnaya Zemlya. The Kara Sea is roughly long and wide with an area of around and a mean depth of . Its main ports are Novy Port and Dikson and it is important as a fishing ground although the sea is ice-bound for all but two months of the year. The Kara Sea contains the East-Prinovozemelsky field (an extension of the West Siberian Oil Basin), containing significant undeveloped petroleum and natural gas. In 2014, US government sanctions resulted in Exxon having unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bering Sea
The Bering Sea ( , ; rus, Бе́рингово мо́ре, r=Béringovo móre, p=ˈbʲerʲɪnɡəvə ˈmorʲe) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and the Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelf, continental shelves. The Bering Sea is named after Vitus Bering, a Denmark, Danish-born Russia, Russian navigator, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Berin ...

Bristol Bay
Bristol Bay (, ) is the easternmost arm of the Bering Sea, at 57° to 59° North 157° to 162° West in Southwest Alaska. Bristol Bay is 400 km (250 mi) long and 290 km (180 mi) wide at its mouth. A number of rivers flow into the bay, including the Cinder River, Cinder, Egegik River, Egegik, Igushik River, Igushik, Kvichak River, Kvichak, Meshik River, Meshik, Nushagak River, Nushagak, Naknek River, Naknek, Togiak River, Togiak, and Ugashik River, Ugashik. Upper reaches of Bristol Bay experience some of the highest tides in the world. One such reach, the Nushagak Bay near Dillingham, Alaska, Dillingham and another near Naknek, Alaska, Naknek in Kvichak Bay have tidal extremes in excess of 10 m (30 ft), ranking them — and the area — as eighth highest in the world. Coupled with the extreme number of shoals, sandbars, and shallows, it makes navigation troublesome, especially during the area's frequently strong winds. As the shallowest pa ...
