Estimating premature mortality of adult Harrison sockeye salmon

In this project we propose to tag Harrison sockeye upon entry into the Harrison River across the entire migration period, from late July through to mid-October (the beginning of spawning ground assessments), to accurately estimate premature mortality and quantify mortality in relation to river entry timing for this system. This project will reduce the uncertainty in the relationship between Harrison sockeye migration timing past Mission and survival to spawning.
