Title: Disease in Pacific salmonids: research, monitoring, and management


Along the west coast of the United States, pathogens and disease have been linked to declining numbers of salmonids and identified as a stressor resulting in mortality. Disease can result in the ultimate or proximate cause of fish mortality. In adult salmon, morality events spurred by diseased are commonly observed under high spawning densities and warm water temperatures. In juvenile salmon, pathogens and diseases cause acute mortality but can also impact swimming performance and susceptibility to predation. There are many unanswered questions regarding the linkages between environmental conditions and the role that pathogens and disease play in salmon population productivity. During this workshop we will 1) explore our current state of knowledge about salmon pathogens and disease in California, 2) learn about the tools that are available and being developed to better study disease and disease impacts, 3) examine cases studies from other river systems that have integrated monitoring and research to manage in-season disease effects on salmon, and 4) identify key information and knowledge gaps necessary to fill to guide research and management of pathogens and disease in wild salmon populations.
