European Whitefish Dezadeash Lake small-bodied population
Scientific Name: Coregonus lavaretus
Taxonomy Group: Fishes
COSEWIC Range: Yukon
COSEWIC Assessment Date and Status Change: April 2018
COSEWIC Status: Threatened
COSEWIC Status Criteria: D2
COSEWIC Reason for Designation: European Whitefish are a species complex that has coevolved in certain lakes as species pairs—a larger species and a smaller species. This smaller species is known from a single lake in southern Yukon. Its persistence is threatened by the risk of establishment of invasive species that could alter the ecological niches of the species pair. If exotic species invade, this fish could become extinct in a short period of time.
COSEWIC History of Status Designation: Squanga Whitefish (Coregonus sp.) was considered a single unit and designated Special Concern in April 1987. In April 2018, the unit was split into three separate species of European Whitefish, Coregonus lavaretus, and the Dezadeash Lake small-bodied population of European Whitefish was designated Threatened.

Species that have been designated at risk by COSEWIC since the Species at Risk Act (SARA) was written must be added to Schedule 1 through a regulatory amendment. Information on this procedure is available in the Assessment section. If European Whitefish, Dezadeash Lake small-bodied population, is added to Schedule 1, it will benefit from the protections afforded by SARA. More information about SARA, including how it protects individual species, is available in the Species at Risk Act: A Guide.

PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.

COSEWIC Annual Reports
COSEWIC Annual Report 2017 to 2018 (2018-10-15)Over the past year COSEWIC assessed a total of 90 wildlife species and 11 of these were assigned a status of Not at Risk. Of these 90, COSEWIC re-examined the status of 38 wildlife species; of these, the majority (87%) were reassessed at the same or lower level of risk. To date and with the submission of this report, COSEWIC’s assessments now include 771 wildlife species in various risk categories including 338 Endangered, 183 Threatened, 228 Special Concern, and 22 Extirpated (i.e. no longer found in the wild in Canada). In addition, 18 wildlife species have been assessed as Extinct, and a total of 59 wildlife species have also been designated as Data Deficient and 197 have been assessed and assigned Not at Risk status.
