Many across Alberta are putting out another call to help prevent whirling disease

Whirling disease was first detected in Canada in August 2016 at Johnstone's Lake in Baff National Park.

The disease itself is caused by a type of parasite that affects the way juvenile fish grow, potentially killing 90% of juveniles in susceptible fish.

Lesley Peterson, Provincial Biologist for Trout Unlimited says the disease greatly affects the fish's chances of survival by causing it to swim in the whirling motion. 

"When the parasite attaches to the fish it attacks the cartilage of the fish which causes damage making them swim in a whirling pattern, this limits their ability to swim, avoid predators and fight strong currents" 

The disease is still being tracked and identified throughout the province and the government is currently working on a project that determines the conditions the parasite prefers. 

"We know that its present in the bow river, and other areas of the watershed, its also present in the Red Deer watershed, Old Man Watershed and now also the north Saskatchewan watershed." 

There currently isn't any treatment for Whirling disease making the prevention of Whirling disease crucial to protect the environment, waterways and fish populations. The best way to prevent the spread of Whirling Disease and other invasive species is actually quite simple, clean, drain and dry all gear that has been used in infected areas. 

" Its really important for people when they are going from one place to another to clean, drain and dry your gear. If your fishing in the Bow River for example after your done make sure you really scrub your boots clean, and any other fishing gear or even better have specific gear for specific areas."

If you are fishing in an area and find a fish that shows exhibits of whirling disease contact Alberta Environment And Parks and report the incident as well as take photos.
