The PSRC will work closely with and support the Monterey Bay Aquarium, National Marine Fisheries Service (NMFS), and Tagging of Pacific Pelagics (TOPP) programs to tag, release, track, and recapture sharks in central and southern California. We will work with NMFS Southwest Fisheries Science Center colleagues during summer tagging and tracking cruises and in cooperation with NMFS Santa Cruz Laboratory staff during their nearshore coastal long-line and trawl surveys to further develop tag and release procedures. The PSRC will coordinate with MLML graduate student research actively tracking prickly sharks (Echinorhinus cookei) and leopard sharks (Triakis semifasciata) in the Monterey Bay region. Using an array of receivers placed throughout Elkhorn Slough, passive tracking techniques will also be implemented to monitor longer term movement patterns and habitat use. These studies will serve to provide an improved understanding of movement patterns, habitat use, and age validation of Pacific sharks.
