Biography

Dr. Mark Poesch is an Associate Professor in the Department of Renewable Resources at the University of Alberta and the lead of the Fisheries and Aquatic Conservation Laboratory. He is also an Executive Committee Member (and former President) of the Canadian Aquatic Resources Section (CARS) of the American Fisheries Society, the largest professional fisheries organization in the world, as well as an Associate Editor of the Canadian Journal of Fisheries and Aquatic Science, the leading journal addressing original research in fisheries and aquatic ecology. He works with two groups (USchool & Tracking Change) that highlight research opportunities to at-risk youth.

His research focuses on three related objectives in aquatic conservation and fisheries management. The main research objectives are to: 1) understand the loss of aquatic biodiversity due to global change, 2) understand dispersal/connectivity of freshwater fish populations, and 3) develop novel approaches for the management of aquatic biodiversity. Dr. Poesch’s research focuses on developing improved methods for understanding the mechanisms related to the loss of aquatic biodiversity and restoring species and their habitats. Dr. Poesch is a leading expert on preservation and restoration of fish species at risk and has published many scientific papers on fish species at risk. He is a member of both the provincial and federal groups that determine candidate listing of freshwater fish species at risk.
