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 36.0 cm (14.2 inches), 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 (65.6 feet) below surface. It feeds on zooplankton, especially Cladocera and Daphnia. [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 brown trout is a species of salmonid ray-finned fish and the most widely distributed species of the genus Salmo, endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range.
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.
Sea trout is the common name usually applied to anadromous (sea-run) forms of brown trout, and is often referred to as Salmo trutta morpha trutta. Other names for anadromous brown trout are bull trout, sewin (Wales), peel or peal, mort, finnock (Scotland), white trout (Ireland), Dollaghan and salmon trout (culinary).
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 Oldest Dryas is a biostratigraphic subdivision layer corresponding to a relatively abrupt climatic cooling event, or stadial, which occurred during the last glacial retreat. The time period to which the layer corresponds is poorly defined and varies between regions, but it is generally dated as starting at 18.5–17 thousand years (ka) before present (BP) and ending 15–14 ka BP. As with the Younger and Older Dryas events, the stratigraphic layer is marked by abundance of the pollen and other remains of Dryas octopetala, an indicator species that colonizes arctic-alpine regions. The termination of the Oldest Dryas is marked by an abrupt oxygen isotope excursion, which has been observed at many sites in the Alps that correspond to this interval of time.
Ferox trout is a variety of trout found in oligotrophic lakes/lochs of Ireland, England, Scotland and Wales. Ferox trout is a traditional name for large, piscivorous trout, which in Scotland feed largely on Arctic char. It has been argued to be a distinct species, being reproductively isolated from "normal" brown trout of the same lakes, particularly in Ireland. However, it is uncertain whether the ferox of different lakes are all of a single origin. This fish grows to a length of 80 centimetres (31 in) SL.
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 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.
This a list of extant freshwater fish that could be found in Spain. The majority of the fish present are from the order Cypriniformes. This list states if the fish are native or introduced. For clarification, an endemic species is a species that is found only in a specific geographic region. IUCN status represents the extinction risk for each species and the fish found in Spain range from least concern to critically endangered.
Piscicola geometra is a species of leech in the family Piscicolidae. It is an external parasite of marine, brackish and freshwater fishes. It was first described as Hirudo geometra by the Swedish naturalist Carl Linnaeus in his Systema Naturae in 1758.
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 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 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.
