Peter’s research focuses on understanding the physiological mechanisms behind fish responses to angling in addition to identifying the best techniques to ensure optimal fish recovery. His work aims to evaluate the mechanistic, physiological changes occurring in a wide variety of charismatic gamefish species that support recreational fisheries. His particular interests lie in the assessment of cardiac and metabolic contributions to common fish behaviours (eg. feeding, predator evasion, refuge seeking), and the ecological implications of changes in these behaviours (ie. habitat use, post-release mortality, reproduction) resulting from fisheries interactions.
