The California Collaborative Fisheries Research Program (CCRFP) is a diverse partnership of volunteer anglers, boat captains, scientists, nongovernmental organizations, and charter companies interested in promoting sustainable fisheries. They have been monitoring California MPAs since 2007. The research team surveyed 12 MPA and 12 reference sites in 2019 and 2020, from Northern to Southern California, and worked with 18 commercial passenger fishing vessels and over 300 volunteer anglers during that time. CCFRP uses standardized fishing gear and sampling protocols to catch, measure, tag, and release fish caught inside and outside of MPAs, thus providing information about the abundance, size, biomass, diversity, and movement patterns of fishes in nearshore waters.
The team documented significant changes in abundance, size, and biomass of fishes inside and outside of MPAs over time. Fish are more abundant, larger in size, and greater in biomass inside the MPAs across the state compared to reference areas open to fishing. The strength of the MPA response depended on the intensity of fishing outside the MPAs; in locations with light fishing pressure, biomass increased both inside and outside the MPAs, while in locations with heavy fishing pressure, biomass increased only inside the MPAs. Results also indicated that larger MPAs across the state experienced greater increases in species abundance and overall biomass than smaller MPAs.
The team also created education and outreach materials to share with volunteer anglers, academics, resource managers, and the general public about the CCFRP program, marine reserves, and fisheries management. The team found that with education and relationship building through the CCFRP program, anglers develop a significantly more positive attitude about MPAs.
