This document summarizes an analysis of spatial and socioeconomic data from commercial fisheries in support of a Joint Management Plan Review for three National Marine Sanctuaries. It outlines using fishermen's local knowledge to create profiles of fisheries in the study area and analyzing data from the California Department of Fish and Game on species caught, gear used, landings, and locations. Interviews with 25 local fishermen were also conducted to identify and rank critical fishing grounds. Next steps included finalizing a report and developing an online GIS tool to interact with the data.
