Abstract: Knowledge of fish movements and migrations are critical to understanding fish population dynamics. In Prince William Sound (PWS) adult herring disperse after spawning, however their movement patterns are poorly understood. Currently the only information on adult herring movements are a small number of observations from fishers that suggest PWS herring are regularly migrating out of PWS and onto the shelf. This proposal focuses on verifying adult Pacific herring movements using detections of tagged fish. The Herring Marking Workshop sponsored by EVOS in December 2008, reviewed all potential marking methods for herring and conditionally endorsed acoustic tagging as a method for determining herring movements. This pilot project will acoustic tag adult herring during November around Port Gravina, a spring spawning area. During the second season a small sample of adult herring will be tagged during spring at other spawning areas. We will then examine detections from two, established Pacific Ocean Shelf Tracking (POST) Project’s acoustic arrays as well as new arrays to be deployed at the major entrances and passages to Prince William Sound. These acoustic arrays will enable us to determine seasonal movement patterns within and out of Prince William Sound. The proposed project builds on our previous and current research on acoustic-tagged fishes. This project will synergize with efforts of POST and the Ocean Tracking Network (OTN). The ability to track herring is critical to answer many questions including those about stock structure, migration habits, and the occurrence of skip-spawning. Determining the capabilities of this technology will help guide our choice of future research emphasis.
