Waterways in B.C.’s Mount Robson Park to be shut to prevent whirling disease
VICTORIA — Lakes, rivers and streams in Mount Robson Park in central British Columbia are being closed to all watercraft and wading gear in an effort to prevent the spread of whirling disease in fish.
The B.C. Ministry of Environment and Parks says there’s no indication the parasite that causes fatal deformities and circular swimming patterns in fish is in the park’s waterways, but the ban is cautionary to protect the Fraser River watershed.
There’s no treatment for the infectious disease that attacks the head, spine and nervous tissue, with juvenile trout, salmon and whitefish the most susceptible.
The first case of whirling disease in Canada was detected in Banff in 2016 and since then it has been confirmed in four Alberta watersheds and has spread to Yoho park and Kootenay Lake in eastern B.C.
