Fish Health Program (FHP)

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.

A phylogeny based on cytochrome-c oxidase gene sequences identifies sympatric Ichthyophonus genotypes in the NE Pacific Ocean

ABSTRACT: In recent decades, evidence has accumulated to suggest that the widespread and highly variable parasite Ichthyophonus hoferi is actually a species complex. Highly plastic morphology and a general lack of defining structures has contributed to the likely underestimate of biodiversity within this group. Molecular methods are a logical next step in the description of these parasites, but ma

Rapid diagnostic test to detect and discriminate infectious hematopoietic necrosis virus (IHNV) genogroups U and M to aid management of Pacific Northwest salmonid populations

Infectious hematopoietic necrosis virus (IHNV) is an acute pathogen of salmonids in North America, Europe, and Asia that is phylogenetically classified into five major virus genogroups (U, M, L, E, and J). The geographic range of the U and M genogroup isolates overlap in the North American Columbia River Basin and Washington Coast region, where these genogroups pose different risks depending on th

Comparative virulence of spring viremia of carp virus (SVCV) genotypes in two koi varieties

Spring viremia of carp virus (SVCV), is a lethal freshwater pathogen of cyprinid fish, and Cyprinus carpio koi is a primary host species. The virus was initially described in the 1960s after outbreaks occurred in Europe, but a global expansion of SVCV has been ongoing since the late 1990s. Genetic typing of SVCV isolates separates them into 4 genotypes that are correlated with geographic origin: I

Partners - FHP

For more than five decades the WFRC Fish Health Program has worked with partners to provide research findings to managers of aquatic resources. Those partners form a network of colleagues, co-investigators, and customers. Our partners include Department of the Interior bureaus, tribal and state fisheries agencies, other federal partners and the private sector.
