Research Location: Prince William Sound

Restoration Category: Monitoring, Research

Injured Resources Addressed: Pacific Herring

Abstract:

We will investigate fish health factors that may be contributing to the failed recovery of Pacific herring populations in Prince William Sound. Field samples will provide infection and disease prevalence data from Prince William Sound and Sitka Sound, serological data will indicate the prior exposure history and future susceptibility of herring to viral hemorrhagic septicemia virus (VHSV), and diet information will provide insights into Ichthyophonus transmission mechanisms. Laboratory studies are intended to validate the newly developed plaque neutralization assay as a quantifiable measure of herd immunity against VHS and provide further understanding of disease cofactors including salinity and investigate possible routes of transmission. Information from the field and laboratory studies will be integrated into the current ASA model and inform a novel ASA-type model that is based on the immune status of herring age cohorts.
