Session Coordinator: 
Cynthia LeDoux-Bloom, Ph.D., AECOM

The purpose of the session is to learn about the current status of important viral, bacterial, and parasitic pathogens and their physiological and behavioral effects on Pacific salmonids. Specifically, Infectious Hematopoietic Necrosis Virus, Renibacterium salmoninarum, Myxobolus cerebralis, Ceratonova shasta (aka Ceratomyxa), Ichthyophthirius multifiliis, and other emerging pathogens will be addressed. Topics include stress associated pathogenesis from trapping, handling, tagging, holding, transport, poor water quality conditions, drought, climate change, and pathogen-host relationship imbalances.

Panel Discussion- Linking Salmonid Health and Restoration Planning

Overall fish health has been identified as a critical factor affecting population fitness across every salmonid life history stage; however, recovery efforts rarely prioritize disease diagnoses, prevalence, or prevention.  The results of very expensive, large scale habitat restoration efforts aimed at salmon recovery can be superseded by unknown and unstudied microscopic infectious agents and organisms.
