FHB Home       Staff       Research       Products       Directions



The Fish Health Branch investigates persistent and emergent health issues associated with genetics, pathogens and environmental stressors that undermine conservation and restoration of interjurisdictional populations including depleted, threatened, or endangered fishes and aquatic organisms.



The Fish Health Branch conducts integrated research to understand and solve emerging and known disease problems, both infectious and non-infectious, affecting fish and other aquatic resources. Resolution of these health problems is accomplished through research utilizing a variety of disciplines including microbiology, parasitology, virology, immunology, histopathology, molecular biology, and aquatic toxicology for the purpose of providing science support for the Department of the Interior’s wise stewardship of natural resources.
