Bull Trout Redd Surveys
Bull trout are an apex predator in the Kootenay Region, and can reach sizes up to 90 cm and 10 kg. They are indicators of ecosystem health, as they require specific habitats for their various lifestages, and are sensitive to habitat degradation.Bull trout migrate into tributaries in the fall to spawn, and counting the number of redds (nests) is a reliable way of monitoring bull trout populations. Masse Environmental has completed bull trout redd surveysin tributaries to the Duncan Reservoir, Trout Lake, and Kootenay Lake.
