Salvelinus struanensis, commonly known as Scottish char, is a species of freshwater fish in the salmon family. It is found in the Loch Rannoch and Loch Ericht in Scotland, United Kingdom.
The maximum recorded length of the fish can reach 36 cm (14.2 in), and a maximum recorded age of 8 years. [2] The fish has an overall claret color in breeding season with dark fins and orange-pink spots. [2] The fish does not have parr marks and body fusiform as compared to congeners in central Scotland. [3]
The species is found in the pelagic zone of fjord-like lakes, usually less than 20 m (70 ft) below surface. It feeds on zooplankton, especially Cladocera and Daphnia. [4]
The brook trout is a species of freshwater fish in the char genus Salvelinus of the salmon family Salmonidae native to Eastern North America in the United States and Canada. Two ecological forms of brook trout have been recognized by the US Forest Service. One ecological form is long-lived potamodromous populations in Lake Superior known as coaster trout or coasters. The second ecological form is the short-living predaceous anadromous populations which are found in northern lakes and coastal rivers from Long Island to Hudson Bay, which are referred to as salters. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook char, squaretail, brookie, or mud trout, among others. Adult coaster brook trout are capable of reaching sizes over 2 feet in length and weigh up to 6.8 kg (15 lb), whereas adult salters average between 6 and 15 inches in length and weigh between 0.5 and 2.3 kg. The brook trout is characterized by its distinctive olive-green body with yellow and blue-rimmed red spots, white and black edged orange fins, and dorsal vermiculation. The diet of the brook trout is restrictive to the season and location of the fish, but will typically consist of terrestrial and aquatic insects, fry, crustaceans, zooplankton, and worms.
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.
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.
St Mary's Loch is the largest natural loch in the Scottish Borders, and is situated on the south side of the A708 road between Selkirk and Moffat, about 72 kilometres (45 mi) south of Edinburgh.
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.
Loch Mealt is an inland fresh-water loch on the Isle of Skye in Scotland. It lies close to Ellishadder and south of Staffin, on the eastern side of the Trotternish peninsula.
Salvelinus inframundus, also known as Orkney charr is a cold-water fish in the family Salmonidae which is endemic to Scotland.
Salvelinus killinensis, also known as Haddy charr is a variety of charr found in certain lakes in Scotland.
Salvelinus umbla, also known as lake char, is a species of char found in certain lakes of the region of the Alps in Europe.
A kype is a hook-like secondary sex characteristic which develops at the distal tip of the lower jaw in some male salmonids prior to the spawning season. The structure usually develops in the weeks prior to, and during, migration to the spawning grounds. In addition to the development of the kype, a large depression forms in the two halves of the premaxilla in the upper jaw, allowing the kype to fit into the premaxilla when the mouth is closed.
The Coomsaharn char is a species of lacustrine char fish in the family Salmonidae.
Salvelinus willughbii, also known as the Windermere charr or Willoughby's charr, is a cold-water fish in the family Salmonidae. Its binomial species name commemorates Francis Willughby. They are remnants from the end of the last ice-age, landlocked and isolated in various lakes within Cumbria, England. S. willughbii are a subspecies of Arctic charr that inhabit Lake Windermere, Coniston Water, Wast Water, Ennerdale Water, Buttermere, Crummock Water, and Loweswater in The Lake District of Cumbria, England. The species has been listed on the IUCN Red List as Critically Endangered due to increased water temperatures, decreased levels of oxygen, and overfishing within Lake Windermere.
The Sommen charr is a population or subspecies of Arctic charr found in Lake Sommen. It is one of twenty-two species of fish found in the lake.
Salvelinus lonsdalii, also known as Haweswater char or Lonsdale char, is a species of freshwater fish in the salmon family. It is endemic to the Haweswater Reservoir in England and was listed as critically endangered by IUCN in 2008, though this was revised to Vulnerable in 2023.
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 taimyricus, commonly known as the taimy char, is a species of freshwater fish in the salmon family. It is found in the Lake Taymyr at the Taymyr Peninsula in Arctic Russia.
