Abstract: The Pacific herring population of Prince William Sound has not recovered from severe population decline in 1993. Viral hemorrhagic septicemia (VHS) virus and the fungus Ichthyophonus hoferi were identified as the two main diseases during a multi-year research project that closed out in FY 98 (Project /162). Prevalence of Ichthyophonus decreased after 1995, but an unexpected increase in the prevalence of VHS virus in 1997 might delay recovery. To determine if disease continues to impair recovery, and to document recovery when it occurs, this project will monitor prevalence of the two major diseases in Pacific herring in Prince William Sound twice annually, from October 1998 through April 2001.
