Lake Whitefish Squanga Lake large-bodied population
Scientific Name: Coregonus clupeaformis
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: Lake Whitefish and European Whitefish are a species complex that has coevolved in certain lakes as species pairs—a larger species and a smaller species. This species is known from a single lake in southern Yukon, where it coexists with a smaller species derived from the European Whitefish. 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: Designated Threatened in April 2018.
SARA Status: No schedule, No Status
