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.

Long-term shedding from fully convalesced individuals indicates that Pacific herring are a reservoir for viral hemorrhagic septicemia virus

Processes that allow viral hemorrhagic septicemia (VHS) virus to persist in the marine environment remain enigmatic, owing largely to the presence of covert and cryptic infections in marine fishes during typical sub-epizootic periods. As such, marine host reservoirs for VHS virus have not been fully demonstrated, nor have the mechanism(s) by which...

Virus shedding kinetics and unconventional virulence tradeoffs

Tradeoff theory, which postulates that virulence provides both transmission costs and benefits for pathogens, has become widely adopted by the scientific community. Although theoretical literature exploring virulence-tradeoffs is vast, empirical studies validating various assumptions still remain sparse. In particular, truncation of transmission...

Survival and growth of suckers in mesocosms at three locations within Upper Klamath Lake, Oregon, 2018

Executive SummaryDue to high mortality in the first year or two of life, Lost River (Deltistes luxatus sp.) and Shortnose suckers (Chasmistes brevirostris sp.) in Upper Klamath Lake, Oregon rarely reach maturity. In 2015, the U.S. Fish and Wildlife Service began the Sucker Assisted Rearing Program (SARP) to improve early life survival before...
