Our laboratory maintains broad interests in all aspects of aquatic ecology, conservation biology, physiological ecology, animal behaviour and environmental science. Freshwater and marine fishes are used as research models for experiments conducted in laboratory tanks, experimental ponds, and most commonly, field sites. Specific interests are (1) determining the energetic, fitness, and potential evolutionary consequences of a variety of natural (e.g., winter, reproduction) and anthropogenic (e.g., angling, environmental pollution) stressors and, (2) understanding the diversity of energetic, physiological, and behavioural responses of fish to stress at the individual, population, and species level. We then apply the fundamental knowledge derived from these basic research activities to aid in the conservation and management of aquatic resources. Of late, we have been involved with defining the new discipline of “conservation physiology” – a field dedicated to understanding the mechanisms underlying conservation problems. Because our work is heavily based in the field, we rely on technologies including underwater videography and telemetry to monitor free-swimming fish in the wild.
Our current and prospective research activities focus on three specific study systems that enable us to test hypotheses associated with our research programme and to address applied issues in fish ecology. Our work is currently focused on temperate centrarchid fishes (the sunfish) in Midwestern North America, the Pacific salmonids of British Columbia, and flats and mangrove communities of the Caribbean. Although these systems are all rather disparate in geography, there are common problems and challenges experienced by fish in these very different environments. Specific research projects currently underway include assessment of the compatibility of catch and release angling with marine protected areas, evaluation of the physiological correlates of reproduction and fitness, and understanding the factors influencing the spatial ecology of fish.
