Coregonus nilssoni

Coregonus nilssoni is a putative species of whitefish, part of the Coregonus lavaretus complex (European whitefish). [1] It is a pelagic fish feeding on zooplankton. Its distribution is in lakes of Sweden, southern Norway, Denmark and Poland. [1]

In Sweden, the name C. nilssoni has referred to a form of whitefish known as the planktonsik. That is however no more considered a distinct species but an ecotype within Coregonus maraena ("Coregonus maraena morphotype nilssoni"), and not different from " Coregonus maraena morphotype megalops ".

<i>Coregonus</i> Genus of fishes

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.

<i>Coregonus albula</i> Species of fish

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.

Atlantic whitefish Species of fish

The Atlantic whitefish is a coregonine fish inhabiting some freshwater lakes within Nova Scotia, Canada. It is known to survive only in the Petite Rivière watershed as landlocked populations. Earlier it was also found in the Tusket and Annis rivers of Nova Scotia. Those populations were anadromous, migrating to the estuary to feed while breeding in freshwater.

Freshwater whitefish Subfamily of fishes

The freshwater whitefish are fishes of the subfamily Coregoninae, which contains whitefishes and ciscoes, and is one of three subfamilies in the salmon family Salmonidae. Apart from the subfamily Coregoninae, the family Salmonidae includes the salmon, trout, and char species of the subfamily Salmoninae, and grayling species of the subfamily Thymallinae. Freshwater whitefish are distributed mainly in relatively cool waters throughout the northern parts of the Northern Hemisphere.

Houting European extinct fish

The houting is a European, allegedly extinct species of whitefish in the family Salmonidae. It is 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.

Humpback whitefish Species of fish

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.

<i>Sarcosoma</i> Genus of fungi

Sarcosoma is a genus of fungi in the family Sarcosomataceae. The genus, widespread in north temperate and tropical areas, contains 16 species. The anamorph (asexual) form is the genus Verticicladium.

European whitefish can refer to several fish in the genus Coregonus:

<i>Coregonus maraena</i> Species of fish

Coregonus maraena, referred to in English as the maraene, maraena 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.

Lake whitefish Species of fish

The lake whitefish is a species of freshwater whitefish from North America. Lake whitefish are found throughout much of Canada and parts of the northern United States, including all of the Great Lakes. The lake whitefish is sometimes referred to as a "humpback" fish due to the small size of the head in relation to the length of the body. It is a valuable commercial fish, and also occasionally taken by sport fishermen. Smoked, refrigerated, vacuum-packed lake whitefish fillets are available in North American grocery stores. Other vernacular names used for this fish include Otsego bass, Sault whitefish, gizzard fish, common whitefish, eastern whitefish, Great Lakes whitefish, humpback whitefish, inland whitefish and whitefish.

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.

Coregonus pallasii is a putative species of whitefish in the family Salmonidae, part of the Coregonus lavaretus complex.

Coregonus megalops is a putative species of whitefish, part of the Coregonus lavaretus complex. Its distribution is in Sweden, Finland and Russia.

Agathidium pulchellum is a species of round fungus beetle in the family Leiodidae. It feeds exclusively on a slime mold species associated with mid-decayed aspen, spruce and birch logs in boreal forests. It was first discovered in 1971 in Blåkölen in Norrbotten, Sweden.
