Fish Health Program (FHP)
Home
The Fish Health Program conducts science focused on understanding the control, distribution and severity of infectious diseases affecting hatchery and wild fish. Our research projects are national and international in scope but have a major focus on fish health issues in the western landscapes of the Columbia River, Puget Sound and Klamath Basin.
Tribal Collaborations
The Fish Health Program has a strong commitment to respond to requests for research and technical support from Tribal fisheries agencies.

Disease in Central Valley salmon: Status and lessons from other systems
Chinook Salmon (Oncorhynchus tshawytscha) are increasingly vulnerable to anthropogenic activities and climate change, especially at their most southern species range in California’s Central Valley. There is considerable interest in understanding stressors that contribute to population decline and in identifying management actions that reduce the...

Piscine orthoreovirus (PRV-1) is a segmented RNA virus which is commonly found in salmonids in the Atlantic and Pacific Oceans. PRV-1 causes the Heart and Skeletal Muscle Inflammation (HSMI) disease in Atlantic salmon and is associated with several other disease conditions. Previous phylogenetic studies of genome segment 1 (S1) identified four...

The genomic loci encoding the four immunoglobulin light chains (IgL1, IgL2, IgL3, and IgL4) in the Swanson trout genome assembly were annotated in order to provide a measurement of the potential IgL repertoire. IgL1 and IgL3 gene segments are co-localized on chromosomes 21, 18, 15, and 7 while IgL2 and IgL4 were found on chromosomes 13 and 17,...
