Coregonus is a diverse genus of fish in the salmon family (Salmonidae). The Coregonus species are known as whitefishes. The genus contains at least 68 described extant taxa, but the true number of species is a matter of debate. The type species of the genus is Coregonus lavaretus.
Coregonus lavaretus is a species of freshwater whitefish, in the family Salmonidae. It is the type species of its genus Coregonus.
The gwyniad is a freshwater whitefish native to Bala Lake in northern Wales.
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 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.
The gravenche, also known as the Lake Geneva whitefish or the little fera, is a presumably extinct freshwater fish from Lake Geneva in Switzerland and France.
Coregonus fera, commonly called the true fera, is a presumed extinct freshwater fish from Lake Geneva in Switzerland and France.
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 houting is a European species of whitefish in the family Salmonidae that was long thought extinct. It was native to the estuaries and rivers draining to the North Sea. The houting is distinguishable from other Coregonus taxa by having a long, pointed snout, an inferior mouth and a different number of gill rakers. The houting once occurred in Belgium, France, Germany, the Netherlands and England. In 2023, DNA analysis found the houting to be genetically indistinguishable from Coregonus lavaretus, and therefore not extinct.
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.

Coregonus fontanae, also known as the Stechlin cisco, Fontane cisco, or Fontane's cisco, is a putative species of freshwater whitefish in the family Salmonidae endemic to the Großer Stechlinsee in northern Germany. It is believed to have recently evolved from the sympatric vendace, Coregonus albula.
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 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.
The Peipsi whitefish is a freshwater whitefish of the family Salmonidae that naturally occurs in Lake Peipus on the border of Estonia and Russia, from where it also ascends to Lake Võrtsjärv to spawn. It has been introduced in Lake Burtnieks (Latvia), Gulf of Riga, many lakes of northern Russia, Poland, Germany, Netherlands, Japan, Lake Sevan (Armenia) and Balkash (Kazakhstan). It is a benthopelagic fish up to 60 cm long.
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.
Salvelinus profundus is a deepwater char species found only in deep areas of Lake Constance.
Coregonus widegreni, also called the Valaam whitefish, is a putative species of freshwater whitefish, a part of the common whitefish complex from Northern Europe. It is a demersal form of freshwater whitefish that feeds on benthic invertebrates. It spawns in late autumn, and can reach a length of 55 cm maximum. It is characterized by a low gill raker density.
