Salvelinus czerskii, also known as Cherskii's char, is a freshwater species of fish of the genus salvelinus found in the Indigirka and Chukochya river basins in Arctic Russia. [1] [2]
The Cherskii's char can grow to a recorded maximum length of 75 cm (29.5 inches). [3] The species is benthopelagic, residing at or near the bottom of the river. The species breed between August and September, laying eggs on muddy ground and shallow shores. [4]
The fish has low caudal stalk and strongly notched caudal fin. There are few light or pinkish spots on both sides mainly located along the lateral line. [5] During the breeding season, the spots on the sides turn red, and the throat and lower jaw turn yellow. The paired and anal fins are bright red, and their outer rays are white. [6]
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes, consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids". The family includes salmon, trout, char, graylings, freshwater whitefishes, taimens and lenoks, all coldwater mid-level predatory fish that inhabit the subarctic and cool temperate waters of the Northern Hemisphere. The Atlantic salmon, whose Latin name became that of its genus Salmo, is also the eponym of the family and order names.
The Arctic char or Arctic charr is a cold-water fish in the family Salmonidae, native to alpine lakes, as well as Arctic and subarctic coastal waters in the Holarctic.
The Dolly Varden trout is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. Despite the name "trout", it belongs to the genus Salvelinus (chars), which includes 51 recognized species, the most prominent being the brook, lake and bull trout as well as the Arctic char. Although many populations are semi-anadromous, riverine and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.
Salvelinus is a genus of salmonid fish often called char or charr; some species are called "trout". Salvelinus is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea.
The spoonhead sculpin is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is widespread in northeastern North America.
The Pacific staghorn sculpin is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in the eastern Pacific Ocean. It is the only species in the monospecific genus Lepidocottus.
The fourhorn sculpin is a species of ray-finned fish belonging to the family Cottidae, the typical sculpins. This species has a Holarctic distribution and can be found in marine, brackish and fresh waters.
Salvethymus svetovidovi, also called the long-finned charr, is a species of salmonid fish. It is endemic to Elgygytgyn Lake in Chukotka, Far East of Russia, together with another species, the small-mouth char Salvelinus elgyticus. A third char species in the same lake is Salvelinusboganidae, the Boganid char.
The Amur sculpin, also known as the Ussuri sculpin, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in eastern Asia where it is found in Russia, China and Mongolia - in the Amur River basin and some adjacent territories. The Amur sculpin grows to a maximum published total length of 20 cm (7.9 in). This species is the only known member of its genus, Mesocottus. According to the result of a pilot phylogenetic analysis, the freshwater Mesocottus is a sister lineage to the Cottus clade.
Salvelinus inframundus, also known as Orkney charr is a cold-water fish in the family Salmonidae which is endemic to Scotland.
Myoxocephalus scorpioides, the Arctic sculpin or northern sculpin, is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This fish is found in the Arctic Ocean.
Salvelinus grayi, also called Gray's char[r], Lough Melvin char[r] or freshwater herring, is a species of lacustrine char in the family Salmonidae.
Salvelinus albus, also known as white char, is a species of freshwater fish in the salmon family. It is endemic to the Kamchatka Peninsula, Russia, including the Lake Kronotskoye drainage basin.
Salvelinus neiva, also known as neiva, is a freshwater species of fish in the salmon family. It is endemic to the Okhota river basin of the Russian far east and mountain lakes nearby.
Salvelinus tolmachoffi, also known as Yessey lake charr, is a freshwater species of fish in the salmon family. It is endemic to Lake Yessey of the Khatanga river basin of the arctic Russia. In 2007, the fish was listed as endangered by IUCN due to over-fishing and poor management of the water body.
Salvelinus alpinus erythrinus, also known as Baikal charr or davatchan, is a subspecies of freshwater fish in the salmon family. It is endemic to the mountains north of Lake Baikal in the Russian Far East. The fish is edible and it is reported that the population of the species shrunk rapidly over the recent years due to over-fishing.
Salvelinus drjagini, also known as Dryanin's charr, is a species of freshwater fish in the salmon family. It is found in the lakes and rivers of the Taimyr Peninsula in arctic Russia. The species is used to produce yellow coloured cavier.
