The Pacific Region Fish Health Program protects the health and welfare of fish living in the wild and on Federal and partner hatcheries in Idaho, Oregon, and Washington. With healthy fish we can be confident that fish survive in the wild to support the Service’s mitigation and recovery goals.

What We Do

Fish Health Program personnel must apply knowledge of several scientific disciplines including fish biology, microbiology, epidemiology, toxicology, pathology, physiology, histology, and genetics. They must understand environmental conditions and fish requirements, the interactions of wild and cultured fish, and how those factors influence disease and overall aquatic animal health.


Normal Fish Health Program activities include:

  • frequently checking on the general health of fish within hatcheries;
  • screening for diseases (viral, bacterial, parasites) dangerous to fish;
  • investigating health problems in wild fish populations;
  • recommending treatments for specific diseases;
  • giving advice on how to prevent or minimize impacts of disease on fish populations.

Our Library

The Pacific Region Fish Health Program produces a publication called the “Fish Health News”.  The News covers all kind of fish health issues, and describes disease organisms, diseases, and management strategies.  Every issue includes many pictures and illustrations, and a very popular section of “Fun Factoids.”
