My research involves assessing how fish respond to fisheries capture and other stressors. My PhD thesis was focused on the effects of fisheries capture on the physiology and post-release fate of adult Pacific salmon undergoing their spawning migration in British Columbia. More recently, I’ve been assessing the behaviour of coral reef fishes after catch-and-release, and examining the behavioural correlates of vulnerability to angling stressors. I’m also interested in evaluating physiological measurements as methods for predicting the fitness of fish and fish populations under climate change scenarios. I’ve begun doing work on the behavioural effects of the elevated levels of dissolved CO2 that are projected to occur for marine fishes this century as a result of climate change, with a focus on fish of the Great Barrier Reef. As a natural follow-on, I’m interested in understanding the potential interactions between climate change (high temperature and CO2) and fisheries capture stressors.
Broadly, my interests span anything that includes examining the effects of stressors on animals, particularly at the organism level. For my work, I combine a variety of techniques, including biotelemetry and biologging, direct observations of fish behaviour in lab and field experiments, assessments of blood and muscle biochemistry, and respirometry.
