Abstract
William Twardek, a 2017 W. Garfield Weston Fellow and colleagues studied the effect of catch and release fishing on wild Steelhead. Their results indicated behavioural impairment of the fish following release after only 10 seconds of air exposure. In addition, estimates of stress levels in Steelhead were higher under warmer water conditions. Steelhead anglers are cautioned to limit air exposure to less than 10 seconds and be extra cautious when water temperature is warmer.
