Coregonus macrophthalmus is a freshwater fish of the family Salmonidae. It can be found in Lake Constance (Austria, Germany and Switzerland). [1]
The gwyniad is a freshwater whitefish native to Bala Lake in northern Wales.
The powan is a kind of freshwater whitefish endemic to two lochs in Scotland, Loch Lomond and Loch Eck. It has been successfully introduced in two other sites, Loch Sloy and the Carron Valley Reservoir.
The pollan or Irish pollan is a freshwater whitefish known only from five Irish lakes, Lough Neagh, Lower Lough Erne, Lough Ree, Lough Derg and Lough Allen. The pollan faces competition from introduced species such as pike, roach and zebra mussel, and the populations rely on restocking for survival.
Coregonus albula, known as the vendace or as the European cisco, is a species of freshwater whitefish in the family Salmonidae. It is found in lakes in northern Europe, especially Finland, Latvia, Lithuania, Sweden, Russia and Estonia, and in some lakes of Norway, the United Kingdom, northern Germany, and Poland. It is also found in diluted brackish water in the Gulfs of Finland and Bothnia, both of which are in the Baltic Sea.
The Arctic cisco, also known as Arctic omul, is an anadromous species of freshwater whitefish that inhabits the Arctic parts of Siberia especially Yenisey Gulf. It can also be found in Alaska and Canada. It has a close freshwater relative in several lakes of Ireland, known as the pollan, alternatively regarded as conspecific with it, or as a distinct species.
The broad whitefish is a freshwater whitefish species. Dark silvery in colour, and like a herring in its shape. Its distinctive features includes: a convex head, short gill rakers, and a mild overbite. It is found in the Arctic-draining streams, lakes, and rivers of far eastern Russia and North America. Its prey includes larval insects, snails, and shellfish. It is eaten by humans and brown bears.
Coregonus sardinella, known as the least cisco or the sardine cisco, is a fresh- and brackishwater salmonid fish that inhabits rivers, estuaries and coastal waters of the marginal seas of the Arctic Basin, as well as some large lakes of those areas.
The schelly is a living fresh water fish of the salmon family, endemic to four lakes in the Lake District, England. Its taxonomy is disputed with some recognizing it as a distinct species and others as a variant of the widespread Eurasian whitefish species Coregonus lavaretus. It is present in Brothers Water, Haweswater, Red Tarn and Ullswater, and the population seems stable in all of these except for Haweswater where it seems to be declining. The main threats it faces are seen to be water abstraction and cormorants, and the fish-eating birds are being culled from Haweswater. The International Union for Conservation of Nature has rated the conservation status of this fish as "endangered".
Coregonus confusus is a freshwater whitefish from Switzerland. It is also known by its native Swiss German common name, spelled pfärrit, pfarrig, and pfärrig. It was described as Coregonus annectens confusus by Victor Fatio in 1885 from syntypes which have been lost in 1902. The species is rare and only known with certainty from Lake Biel. There is also a possibility that it might occur in Lake Neuchâtel. It vanished from Lake Murten in the 1960s due to eutrophication and water level management.
The peled, also called the northern whitefish, is a species of freshwater whitefish in the family Salmonidae. It is found in northern Europe and Asia.
The humpback whitefish, also referred to as the bottom whitefish, the Arctic whitefish or the pidschian, is a species of freshwater whitefish with a northern distribution. It is one of the members in the broader common whitefish complex, or the Coregonus clupeaformis complex. This fish lives in estuaries and brackish water near river mouths, in deltas and in slowly running rivers, in large lakes with tributaries, and floodplain lakes. It can migrate long distances upriver for spawning.
Coregonus trybomi is a freshwater whitefish in the family Salmonidae. It is a spring-spawning type of cisco, which probably has evolved from sympatric vendace independently in a number of Swedish lakes. Only one of those populations survives, and it is therefore considered Critically Endangered by the IUCN Red List. The status of Coregonus trybomi as a distinct species is however questionable. By Swedish authorities it is treated as a morphotype or ecotype, not an independent species. It was listed as "Data Deficient" in 2010 but excluded from the national red list in 2015.
The muksun(Coregonus muksun) is a type of whitefish widespread in the Siberian Arctic waters. It is mostly found in the freshened areas of the Kara and Laptev Seas and up the major rivers, as well as in Lake Taymyr.
Coregonus alpinus is a species of freshwater whitefish in the family Salmonidae. It is endemic to Lake Thun, in Switzerland's Interlaken region, where it is found in deep water. The maximum length recorded for this species is 25 centimetres (9.8 in). It feeds on chironomids and other bottom-dwelling invertebrates. It is known as the kropfer, a name also applied to the probably extinct species Coregonus restrictus.
Coregonus bavaricus, the Ammersee kilch, is a species of freshwater whitefish endemic to Lake Ammersee in the German state of Upper Bavaria. A small, silver-colored fish, it typically lives between 60–85 m (197–279 ft) deep, though shallower in the summer months. In the early 20th century the Ammersee kilch was an important commercial species, but its population declined drastically in the 1930s onward due to overfishing and eutrophication of the only lake in which it is found. Today it is listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) and may be on the verge of extinction.
Coregonus bezola is an extinct species of freshwater whitefish in the family Salmonidae. It was endemic to the Lac du Bourget in Savoie, France where it was pelagic in deep water. The maximum length recorded for this species is 32.0 centimetres (12.6 in). It is known from specimens collected in the late 19th century, and was reported by fishermen to have disappeared in the 1960s. It spawned in January and February, on the muddy bottom of the lake, at a depth of 70 to 80 metres (230–260 ft).
Coregonus maraena, referred to in English as the maraene, maraena whitefish, vendace, cisco, lake herring, lake whitefish or the whitefish, is a whitefish of the family Salmonidae that occurs in the Baltic Sea basin - in the sea itself and the inflowing rivers, and in several lakes as landlocked populations. It is found in Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Netherlands, Norway, Poland, Slovakia, Russia and Sweden. As of 2013, it has been listed as a vulnerable species by the IUCN and as endangered by HELCOM. It is an extremely important fish within the Baltic Sea ecosystem, both for population equilibrium and for the local diets of the surrounding human population. Due to a variety of factors, mostly overfishing, the maraena's population dwindled to near-extinction levels. Thus, rampant repopulation was enacted to preserve this important fish.
Coregonus gutturosus, the Lake Constance whitefish, is an extinct species of whitefish in the salmon family Salmonidae. It was formerly found only in deep areas of Lake Constance in the Alps.
Coregonus restrictus is an extinct freshwater fish from the family Salmonidae. It was originally discovered in Lake Morat, Switzerland, in 1885. In 2008 it was included on the IUCN Red List by J. Freyhof and M. Kottelat. It was first described by Fatio.
Coregonus maxillaris is a species of fish belonging to the family Salmonidae.
