Come out and listen to the challenge whirling disease presents to our fisheries and rivers. Whirling disease was first found in America in the 1950s. Since then, it has been spreading its way into freshwater systems and to the detriment of local fish populations. Whirling disease (Myxobolus cerebralis) is a microscopic parasite that affects salmonid fish such as trout, salmon, and whitefish. The severity of this disease depends on the age and size of the fish host, but has mortality rates as high as 90%. Recently, this disease found its way into four major watersheds of central and southern Alberta: Bow River, Oldman River, Red Deer River, and the North Saskatchewan River.
Join us as we discover why this disease is so damaging and what we can do to manage its spread and preserve our fresh water species!
