Lab results have confirmed presence of Whirling Disease in Banff National Park. This parasitic disease affects some fish species but does not present any health risks for people or other mammals. Westslope Cutthroat Trout (WSCT) are listed as a threatened species in Canada, and are one of the fish species susceptible to the disease. This restriction is in effect to protect critical WSCT habitat from the whirling disease parasite. It will remain in effect until alternate management strategies are implemented. The risk factors for spreading the disease include (in descending order) the movement of: fish, mud/sediment, aquatic vegetation and water.


Violators may be charged under the Canada National Parks Act: maximum penalty $25 000.
