A record number of invasive northern crayfish has been counted in one of Calgary’s northwest water bodies this past week by a volunteer advocacy group, Save Nose Creek.
Parks Canada recently caught a northern crayfish near a stream flowing into Bow Lake in Banff National Park. It’s the first time they’ve seen the aquatic invasive species so far upstream in the Bow River or in the mountain national parks.
The invasive species can be found in other parts of Canada, but so far in Alberta, it's believed to be contained to the north bay of McGregor Lake. Now scientists are trying to create awareness to stop the snails from spreading across the province.
