Synthesizing scientific knowledge about population dynamics and diet preferences of harbour seals, Steller sea lions and California sea lions, and their impacts on salmon in the Salish Sea workshop 2 :...: Fs97-6/3403E-PDF

"In 2019, two bilateral Canada-U.S. workshops were held to outline the scientific knowledge about population dynamics and diet preferences of harbour seals, Steller sea lions and California sea lions, and their impacts on salmon in the Salish Sea. The 2nd was convened in Bellingham, Washington between 20-21 November. The 75 participants included representatives of First Nations, Tribes, stakeholders in the fishing industry and non-profit organizations, as well as scientists from local and federal regulatory agencies and universities. The workshop aimed to 1) provide concise summaries of the current state of scientific knowledge and uncertainties, 2) incorporate other relevant technical knowledge, outline management implications, and recommend possible next steps for science activities necessary to inform management considerations, and 3) asked participants to critique and provide feedback on four areas of action thought to possibly mitigate the impacts of pinnipeds on salmon: variation in hatchery production, enhanced fish survival, non-lethal removal of pinnipeds, and lethal removal of pinnipeds. There was wide variation among attendees on the interpretation of scientific results, the potential efficacy of proposed actions, the degree of risk of a given action, and the level of acceptable risk. This report summarizes the key points from the group discussions to provide focus for future science, management, and policy regarding the impacts of pinnipeds on salmon"--Abstract, page iv.
