Salmonidae is a family of ray-finned fish, the only living family currently placed in the order Salmoniformes. It includes salmon, trout, chars, freshwater whitefishes, and graylings, which collectively are known as the salmonids. The Atlantic salmon and trout of the genus Salmo gives the family and order their names.
Lake Baikal is a rift lake located in Russia situated in southern Siberia between the federal subjects of Irkutsk Oblast to the northwest and Buryatia to the southeast.
The Yenisey, also romanised as Yenisei, Enisei, or Jenisej, is the fifth-longest river system in the world, and the largest to drain into the Arctic Ocean. Rising in Mungaragiyn-gol in Mongolia, it follows a northerly course before draining into the Yenisey Gulf in the Kara Sea. The Yenisey divides the Western Siberian Plain in the west from the Central Siberian Plateau to the east; it drains a large part of central Siberia.
The Selenga or Selenge is a major river in Mongolia and Buryatia, Russia. Originating from its headwater tributaries, the Ider and the Delger mörön, it flows for 992–1,024 kilometres (616–636 mi) before draining into Lake Baikal. The Selenga therefore makes up the most distant headwaters of the Yenisey-Angara river system.
Thymallus is a genus of freshwater fish in the salmon family Salmonidae; it is the only genus of subfamily Thymallinae. The type species is Thymallus thymallus, the grayling. The species in the genus are generically called graylings, but without qualification this also refers specifically to T. thymallus.
Thymallus thymallus, the grayling or European grayling, is a species of freshwater fish in the salmon family Salmonidae. It is the only species of the genus Thymallus native to Europe, where it is widespread from the United Kingdom and France to the Ural Mountains in Russia, but does not occur in the southern parts of the continent. It was introduced to Morocco in 1948, but it does not appear to have become established there.
Grayling or Greyling may refer to:
The Arctic grayling is a species of freshwater fish in the salmon family Salmonidae. T. arcticus is widespread throughout the Arctic and Pacific drainages in Canada, Alaska, and Siberia, as well as the upper Missouri River drainage in Montana. In the U.S. state of Arizona, an introduced population is found in the Lee Valley and other lakes in the White Mountains. They were also stocked at Toppings Lake by the Teton Range and in lakes in the high Uinta Mountains in Utah, as well as alpine lakes of the Boulder Mountains (Idaho) in central Idaho.
The East Siberian grayling(Thymallus pallasii) is a grayling in the salmon family Salmonidae. Males can reach a size of 44 cm (17 in).
Thymallus yaluensis is a putative species of freshwater fish, a grayling in the salmon family Salmonidae. It is endemic to the upper Yalu River in Korea, on the Chinese border.
Lake Khövsgöl is the largest fresh water lake in Mongolia by volume and second largest by area. It is located near the northern border of Mongolia, about 200 km west of the southern end of Lake Baikal. It is nicknamed the "Younger sister" of those two "sister lakes".
The Baikal sturgeon, Acipenser baerii baicalensis, is a sturgeon indigenous to Lake Baikal in Siberia, Russia. It is a subspecies of the widely distributed Siberian sturgeon. It resides primarily in the northern end of the lake, making considerable movements along the shore, and migrating up the Selenga River to spawn. Not long ago, sturgeons weighing 125 kilograms were not uncommon. The Baikal Sturgeon is now listed as endangered.
Comephorus, known as the golomyankas or Baikal oilfish, are a genus comprising two species of peculiar, sculpin fishes endemic to Lake Baikal in Russia. Comephorus is the only genus in the family Comephoridae. Golomyankas are pelagic fishes which make the main food source of the Baikal seal.
The Siberian sturgeon is a species of sturgeon in the family Acipenseridae. It is most present in all of the major Siberian river basins that drain northward into the Kara, Laptev and East Siberian Seas, including the Ob, Yenisei Lena, and Kolyma Rivers. It is also found in Kazakhstan and China in the Irtysh River, a major tributary of the Ob. The species epithet honors the German Russian biologist Karl Ernst von Baer.
Lenoks are a genus, Brachymystax, of salmonid fishes native to rivers and lakes in Mongolia, Kazakhstan, wider Siberia (Russia), Northern China, and Korea.
Coregonus baicalensis is a species of freshwater whitefish in the family Salmonidae. It is endemic to the Russian Federation's Lake Baikal where it is found on the bottom demersal. The maximum length recorded for this species is 60 centimetres (24 in). The average length is a few centimetres above 50 centimetres (20 in). It is also known as the Baikal whitefish. It is frequently considered to be a subspecies of Coregonus lavaretus.
Brachymystax lenok, the sharp-snouted lenok, is a salmonid fish distributed in rivers and lakes in northeastern Asia. It formerly included the blunt-snouted lenok, but recent authorities typically treat the latter as a separate species, B. tumensis, based on differences in morphology and genetics.
The Montana Arctic grayling is a North American freshwater fish in the salmon family Salmonidae. The Montana Arctic grayling, native to the upper Missouri River basin in Montana and Wyoming, is a disjunct population or subspecies of the more widespread Arctic grayling. It occurs in fluvial and adfluvial, lacustrine forms. The Montana grayling is a species of special concern in Montana and had candidate status for listing under the national Endangered Species Act. It underwent a comprehensive status review by the U.S. Fish and Wildlife Service, which in 2014 decided not to list it as threatened or endangered. Current surviving native populations in the Big Hole River and Red Rock River drainages represent approximately four percent of the subspecies' historical range.
Thymallus ligericus, the Loire grayling, is a European freshwater fish species in the salmon family Salmonidae. The species is endemic to the upper Loire drainage in France, where it lives in medium to large foothill, canyon and plateau rivers of the mountainous regions.
