Total number of extinct species is 4.

Two distinct forms of whitefish in Dragon Lake (Quesnel River system) went extinct when the lake was treated with toxaphene (in 1960) to improve a sports fishery. These fish displayed unusual characteristics, which were not discovered until after the lake was poisoned to remove resident native species. Since 1992 Fisheries Program policies require a higher level of inventory to prevent this type of accident.

Two red-listed stickleback species, native to Hadley Lake on Lasqueti Island, were unable to survive the unlawful introduction of an exotic predator. Please don’t move live fish or other aquatic organisms from one water body to another.
