Variation in Responses of Fishes across Multiple Reserves within a Network of Marine Protected Areas in Temperate Waters
Meta-analyses of field studies have shown that biomass, density, species richness, and size of organisms protected by no-take marine reserves generally increase over time. The magnitude and timing of changes in these response variables, however, vary greatly and depend upon the taxonomic groups protected, size and type of reserve, oceanographic regime, and time since the reserve was implemented. We conducted collaborative, fishery-independent surveys of fishes for seven years in and near newly created marine protected areas (MPAs) in central California, USA. Results showed that initially most MPAs contained more and larger fishes than associated reference sites, likely due to differences in habitat quality. The differences between MPAs and reference sites did not greatly change over the seven years of our study, indicating that reserve benefits will be slow to accumulate in California's temperate eastern boundary current. Fishes in an older reserve that has been closed to fishing since 1973, however, were significantly more abundant and larger than those in associated reference sites. This indicates that reserve benefits are likely to accrue in the California Current ecosystem, but that 20 years or more may be needed to detect significant changes in response variables that are due to MPA implementation. Because of the high spatial and temporal variability of fish recruitment patterns, long-term monitoring is needed to identify positive responses of fishes to protection in the diverse set of habitats in a dynamic eastern boundary current. Qualitative estimates of response variables, such as would be obtained from an expert opinion process, are unlikely to provide an accurate description of MPA performance. Similarly, using one species or one MPA as an indicator is unlikely to provide sufficient resolution to accurately describe the performance of multiple MPAs.
2007-2018 CCFRP Statewide Database Public Distribution Metadata
Moss Landing Marine Laboratories (MLML) and Cal Poly San Luis Obispo (CP) worked with central California fishing communities to develop monitoring protocols for the use of hook-andline fishing gear, and to collect baseline information for California Marine Protected Areas (MPAs). The program began by surveying the Año Nuevo, Point Lobos, Piedras Blancas, and Point Buchon MPAs, and in corresponding reference sites, and in the proposed Point Reyes and North and Southeast Farallon Islands MPAs, and near Bolinas/ Duxbury Reef to establish standardized protocols. Within these areas, we used a stratified random sampling design to determine sampling locations. At each location, volunteer anglers fished with standardized gear for a specified amount of time. Caught fishes were identified to species, measured, tagged with external T-bar anchor tags, and released at the location of capture. From 2007 to 2018, we have worked with a total of 15 Commercial Passenger Fishing Vessel (CPFV) captains and 896 volunteer anglers, and caught a total of 83,110 fishes from 63 different species. Due to the success of CCFRP in monitoring central California MPAs, the program expanded statewide in 2017. The program now includes partners from Humboldt State University (HSU), Bodega Marine Laboratory (BML), MLML, CP, UC Santa Barbara (UCSB), and Scripps Institution of Oceanography (SIO). In this inaugural statewide season, 14 MPAs were surveyed over 72 sampling trips. In total, 25,125 fishes were caught and released (4,801 of which were tagged prior to release) over 928 drifts. In combination with the MLML and CP databases dating back to 2007, we have now caught and released 108,235 fishes from 84 different species (45,171 of which were tagged prior to release), and welcomed 1,159 individual anglers in 11 seasons.
