The first suspected case of whirling disease in
Whirling disease doesn't pose a risk to humans, but can be deadly for trout, salmon and whitefish, causing spinal deformities and making fish swim in erratic circles.
Masse said at a news conference on Friday that the high mortality rate among infected fish necessitated the closures in the parks, where at-risk species include westslope cutthroat trout and Kokanee salmon.
"Aquatic invasive species, such as the parasite responsible for whirling disease, threaten freshwater ecosystems and native trout populations, harm infrastructure and reduce aquatic recreational opportunities," Masse said.
"Once established, aquatic invasive species may never go away."
Goudie said the parasite not only lives in fish but can also can thrive in water and mud.
“So, if you're transporting those things on a paddleboard or canoe, angling equipment or gear, that is a very high risk,” said Goudie.
She said the disease is incredibly difficult to eradicate once spread in a watershed.
Masse said it's still too early to say what specific measures might be needed, but the public should respect all closures.
