SilverDoctor Posted August 18, 2020 Posted August 18, 2020 Map of the zones affected by Whirling Disease. A more detailed map of areas here. Good reading, WD has been with us since 2016. Many of us have reported it over the years. https://calgary.ctvnews.ca/parks-canada-drains-alberta-lake-where-whirling-disease-was-first-discovered-1.4639220 https://storymaps.arcgis.com/stories/040b86889ae54c4ab93ae299b9b9397a https://awc-wpac.ca/2019/05/whirling-disease/ https://www.alberta.ca/whirling-disease.aspx 3 Quote
trailhead Posted August 19, 2020 Posted August 19, 2020 I caught a whitefish that was infected with whirling disease in the Bow, in 1994. 1 Quote
toolman Posted August 19, 2020 Posted August 19, 2020 We saw a Whitefish on the Bow near Carsland, with what was likely Whirling disease, in 2010. It swam down the river on the surface, right next to our anchored boat. We tried to scoop him up with the long handled boat net but missed him. His spine/tail was bent in the classic WD shape. There are hardly any RM Whitefish left in the Bow these days. 1 Quote
trailhead Posted August 20, 2020 Posted August 20, 2020 I read somewhere that whites are more susceptible than trout, primarily because they tend to be more of a bottom feeding fish and are more exposed. Quote
