Salvelinus vasiljevae, commonly known as Sakhalinian char, is a species of freshwater fish in the salmon family. It is found in the wider Sakhalin region from Nevelskoy Strait and the Amur river basin.
Sakhalinian char can reach a recorded maximum length of 25.0 cm (9.8 inches). [1] The fish is semi-anadromous, migrating up river to spawn in the middle of summer and autumn. [2] The fish are omnivorous, feeding on fish, aerial and aquatic insects and their larvae, amphipods, on insectivorous mammals and mice. [3] The species usually reside in rapid current and sandy or pebbled bottom in holes (up to 1.5-2 meters). [4]
Trout is a generic common name for numerous species of carnivorous freshwater ray-finned fishes belonging to the genera Oncorhynchus, Salmo and Salvelinus, all of which are members of the subfamily Salmoninae in the family Salmonidae. The word trout is also used for some similar-shaped but non-salmonid fish, such as the spotted seatrout/speckled trout.
The lake trout is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, namaycush,lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish. Those caught with dark coloration may be called mud hens.
Acipenseriformes is an order of basal ray-finned fishes that includes living and fossil sturgeons and paddlefishes (Acipenseroidei), as well as the extinct families Chondrosteidae and Peipiaosteidae. They are the second earliest diverging group of living ray-finned fish after the bichirs. Despite being early diverging, they are highly derived, having only weakly ossified skeletons that are mostly made of cartilage, and in modern representatives highly modified skulls.
The bull trout is a char of the family Salmonidae native to northwestern North America. Historically, S. confluentus has been known as the "Dolly Varden", but was reclassified as a separate species in 1980. Populations of bull trout in the lower 48 states are listed as threatened under the U.S. Endangered Species Act, and bull trout overall are listed as vulnerable to extinction on the IUCN Red List of Threatened Species. The Saskatchewan-Nelson Rivers population in Alberta, Canada is listed as threatened under the Species at Risk Act.
The brook trout is a species of freshwater fish in the char genus Salvelinus of the salmon family Salmonidae. It is native to Eastern North America in the United States and Canada, but has been introduced elsewhere in North America, as well as to Iceland, Europe, and Asia. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook charr, squaretail, brookie or mud trout, among others. A potamodromous population in Lake Superior, is known as coaster trout or, simply, as coasters. Anadromous populations which are found in coastal rivers from Long Island to Hudson Bay are sometimes referred to as salters. The brook trout is the state fish of nine U.S. states: Michigan, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Vermont, Virginia, and West Virginia, and the Provincial Fish of Nova Scotia in Canada.
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 term coldwater fish can have different meanings in different contexts.
The kirikuchi char, Salvelinus leucomaenis japonicus, is a freshwater fish in the family Salmonidae. It is endemic to the Kii Peninsula of central Honshu in Japan. It is the southernmost population of the char genus Salvelinus and is considered a relict in its region. It is usually considered a subspecies of the whitespotted char Salvelinus leucomaenis but was listed as a separate species in the IUCN Red List (1996).
Salvelinus leucomaenis, the whitespotted char, is an East Asian trout in the genus Salvelinus, called iwana in Japanese and kundzha (кунджа) in Russian. Both landlocked and ocean-run forms occur. The landlocked form typically grows up to 35 cm, and prefers low-temperature streams. The seagoing fish typically grows to 70 cm (28 in) long. The largest reported specimen was 120 cm long and the oldest was nine years old.
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.
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 perisii, also known as Torgoch charr, is a freshwater species of fish of the genus Salvelinus found in several lakes such as Llyn Peris, Llyn Padarn and Llyn Cwellyn in Gwynedd County of Wales. The species are listed as vulnerable by IUCN.
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.
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.
