Consequences of catch-and-release angling on the physiology, behaviour and survival of wild steelhead Oncorhynchus mykiss in the Bulkley River, British Columbia

•Steelhead had immediate reflex and behavioural impairment following angling and air exposure of just 10 s.•Blood lactate values were greater in angled fish than baseline levels from dipnetted fish.•Indices of metabolic stress were positively correlated with water temperature.•Estimated survival within 3-days of capture was 95.5%.•Estimated pre-spawn survival was 85%.
