Book Description
Marine Protected Areas (MPAs) are implemented to address a variety of management concerns, including conservation and restoration of fisheries, but few studies assess how MPAs affect regional fishing patterns. Previous research suggests effort will intensify at MPA edges, but few datasets include sufficient pre-implementation data to quantify how MPAs alter fishing effort. We used recreational fisheries data collected by scientific observers aboard Commercial Passenger Fishing Vessels that target nearshore fish species, primarily rockfish. We assessed shifts in the spatial distribution of fishing effort over a 10-year period that includes pre- and post-implementation observations of the California MPA network along the Central Coast. We visually depict fine-scale annual fishing pressure, calculate total regional effort, and identify changing hot spots of fishing activity. While we found no evidence for “fishing the line”, MPA implementation was associated with changes in regional fishing patterns, including contraction of fishing effort away from the northern extent of the region and increased effort intensity in some pre-MPA fishing hotspots. Fishing effort redistribution should be considered in future management decisions regarding California’s MPA network.

Book Description
Marine protected areas (MPAs)—defined geographic areas where fishing and harvesting activity is limited or restricted—have emerged as a popular marine biodiversity and climate resilience strategy worldwide. MPA monitoring efforts often follow MPA designation to help inform the adaptive management of MPAs and MPA networks. In 2012, California completed the largest statewide system of MPAs to date, consisting of 124 MPAs covering 16% of state waters. Following MPA implementation, the state initiated a long-term monitoring program (2019-2022) to help inform the 10-year MPA management review. This two-chapter thesis presents findings from a state-funded project to conduct long-term socioeconomic monitoring for human uses of the MPA network. Chapter 1 describes the novel methodological framework we developed to assess commercial fishing community well-being in relation to long-term MPA management in California. To address the need for standardized, contextual data—and the unique context, scale, and budget constraints of this study—we conducted mixed-methods focus groups with commercial fishing “community-experts” in 18 major California ports/port groups. The focus groups followed a structured, deliberative format that yielded both quantitative and qualitative data. Participants were asked to rate and discuss 15 questions related to fishing community well-being and outcomes from MPAs. Due to pandemic conditions at the time of data collection, focus groups were held over Zoom. Chapter 1 goes on to demonstrate the capabilities of the approach, including the type of data collected and adjustments made in light of the coronavirus pandemic, and discusses participant feedback on the virtual process and lessons learned from the project team’s perspective. Chapter 2 offers an in-depth exploration of the major findings gleaned from the focus group approach discussed in Chapter 1. Results indicated that fishing communities across California were experiencing challenges in their environmental, economic, and social well-being. Results did vary at the port/port group level, suggesting that well-being conditions were uneven across fishing communities. A majority of participants expressed negative views about ecological and livelihood outcomes of MPAs and dissatisfaction with the management of the California MPA network. While MPAs were not reported as the cause of the well-being challenges revealed in the results, focus group data suggested MPAs had interacted with and—in many cases—exacerbated pre-existing well-being challenges, many of which had arisen from structural shortcomings in California fisheries. This study contributes to the growing yet small literature and methodologies on the linkage between community well-being and MPAs, and demonstrates the strengths and capabilities of using a well-being approach for long-term socioeconomic monitoring and adaptive management of MPAs and MPA networks like that in California.

Book Description
Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated for special protection to enhance the management of marine resources. Therefore, there is an urgent need to evaluate how MPAs can be employed in the United States and internationally as tools to support specific conservation needs of marine and coastal waters. Marine Protected Areas compares conventional management of marine resources with proposals to augment these management strategies with a system of protected areas. The volume argues that implementation of MPAs should be incremental and adaptive, through the design of areas not only to conserve resources, but also to help us learn how to manage marine species more effectively.

Book Description
This book focuses on how marine systems respond to natural and anthropogenic perturbations (ENSO, overfishing, pollution, tourism, invasive species, climate-change). Authors explain in their chapters how this information can guide management and conservation actions to help orient and better manage, restore and sustain the ecosystems services and goods that are derived from the ocean, while considering the complex issues that affect the delicate nature of the Islands. This book will contribute to a new understanding of the Galapagos Islands and marine ecosystems.
