Brief synopsis of current research:
As Head of the Habitat and Toxicology Research Section, I currently direct a program of research including generation of new knowledge, technologies, methodologies, and provision of scientific advice concerning the effects of human activities on fish and fish habitat. My own research has focused on developing basic knowledge on relationships between fish and their habitats, habitat productive capacity, effects of resource developments on fish and fish habitat, means to mitigate and compensate for habitat losses due to developments, and applying this knowledge in an applied sense (habitat models, assessment tools) and in the provision of scientific advice. Studies have focused on the effects of long range transport of pollutants, forest harvesting, pulp and paper production, hydroelectric development, road construction, coastal development, mining, and others. In the capacity of Adjunct Professor at the University of Waterloo and Memorial University of Newfoundland, I am involved in research related to the application of telemetry technology to a variety of basic and applied research questions in collaboration with staff and students. This has included: (i) physiological telemetry to assess swimming performance and fishway passage, (ii) movements and habitat use of fish following hydroelectric development, (iii) basic habitat selection studies, (iv) use of coastal habitat by juvenile cod, (v) interaction of escaped aquaculture fish with wild stocks, (vi) validation of flow models, (vii) fish response to varying flows, (viii) effects of transmitter attachment on fish, (ix) application of cardiac output technology for application to fish stress, (x) application of dynamic combined acoustic and radio transmitters, and others.
