We investigated how water temperature and the stressors imposed by encounters with fishing gear (e.g. catch-and-release angling) interact to affect the physiology and survival of sockeye salmon during their upstream reproductive migration. We found that we could use simple observations such as breathing rate and righting response to predict whether individuals would survive after simulated catch-and-release.
