Pathogens of Adult Pacific Salmon in the United States (CA, OR, WA, AK) and British Columbia, Canada

This dataset provides a comprehensive compilation of pathogen records affecting adult anadromous Pacific salmon (Oncorhynchus spp.) during their terminal freshwater migration and spawning across the Pacific Northwest (California to Alaska, United States and British Columbia, Canada). Developed to support a comprehensive review article, to our knowledge this represents the first systematic pathogen database specifically focused on this critical life stage. The dataset contains over 400 records across four categories: macroparasites, microparasites, bacteria, and viruses, covering all five Pacific salmon species (Coho, Chinook, Pink, Sockeye, Chum) and Steelhead Trout. Records may include taxonomic classification, host species, tissue location, environmental context, geographic distribution, and literature references. Additionally, 260 diagnostic case records from the Pacific Biological Station (1973-2016) document disease occurrences across 50 British Columbia locations. This database may update periodically as a living document as additional records are added.
