Parks Canada says it is responding to a suspected case of whirling disease in Yoho National Park, in British Columbia’s southeast Rocky Mountains.

A statement from Parks Canada says it’s the first time the microscopic parasite that causes the disease has been detected in the province.

It says young fish, such as rainbow and brook trout, are especially susceptible to whirling disease, with a mortality rate of about 90 per cent.
