Coregonus trybomi

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 trybomi is a freshwater whitefish in the family Salmonidae. It is a spring-spawning type of cisco, which probably has evolved from sympatric vendace (Coregonus albula) 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.2 By Swedish authorities it is treated as a morphotype or ecotype, not an independent species. It was listed as "Data Deficient" in 20103 but excluded from the national red list in 2015.4
