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.[http://www.slu.se/sv/institutioner/akvatiska-resurser/radgivning/hotade-arter/varsikloja/ Vårsiklöja] Sveriges Landsbrugsuniversitet By Swedish authorities it is treated as a morphotype or ecotype, not an independent species. It was listed as "Data Deficient" in 2010[https://www.havochvatten.se/hav/fiske--fritid/arter/lista-over-vanliga-arter-i-svenska-vatten/arter/varsikloja.html Vårsiklöja (Coregonus trybomi)] Havs- och vattenmyndigheten. but excluded from the national red list in 2015.[http://www.artdatabanken.se/media/2013/hela-boken.pdf Rödlistade arter i Sverige 2015] {{webarchive|url=https://web.archive.org/web/20160304142146/http://www.artdatabanken.se/media/2013/hela-boken.pdf |date=2016-03-04 }}
