Aquatic Animal Health

The fish disease program at the WFRC includes a mix of basic and applied science focused on understanding the factors that control the distribution and severity of infectious diseases affecting both hatchery and wild fish. Aquatic health research includes work in virology, bacteriology, immunology, histology, molecular biology/genetics, fish pathogen ecology, epidemiology, and evolution, and genetics. We continue to develop methods and tools to understand the spread of disease in fish and help inform managers.

Effects of Nanophyetus salmincola on the Health and Survival of Puget Sound Steelhead

Low early marine survival rates of Puget Sound steelhead (Oncorhynchus mykiss), the state fish of Washington, have contributed to its dramatic population decline and current listing as a “Threatened Species” under the Endangered Species Act. Determining the cause(s) of this elevated mortality remains a primary objective of the Salish Sea Marine Survival Project, a large US / Canada effort...

Genomic Mechanisms that Underlie Lack of Recovery of Prince William Sound Herring Following the 1990s Collapse

In the decades following the Exxon Valdez Oil Spill (EVOS), it has become increasingly apparent that oil can be toxic at extremely low concentrations to developing fish embryos including herring, where some toxic phenotypes may be apparent during embryogenesis, but some are delayed until later in life. Therefore, acute and lingering oil may act as an insidious selective force within...

Herring Disease Program

Using an approach that involves a combination of field- and laboratory-based studies, we are investigating fish health factors that may be contributing to the failed recovery of Pacific herring populations in Prince William Sound, AK.  Field studies are providing infection and disease prevalence data to inform the population models, serological data that indicate the prior exposure history and...
