Title: Poaching and the Performance of Marine Reserves as Ocean Management Tools Summary: Noncompliance in fisheries management is unavoidable and is likely to occur in marine reserves. This Master’s thesis presents two models exploring the effects of poaching on a reserve-fishery system: an age-structured reserve model that explores the effects of poaching on the biological and fishery performance of the system under different policy choices for the open area, and a reserve model with logistic population growth and simple poaching fleet dynamics to explore considerations about harvester noncompliance behavior. Both models make similar predictions about the biological and fishery outcomes of poaching. Departures from the traditional assumptions of full compliance to reserve boundaries alter the conclusions of prior modeling work that demonstrate yield equivalence to no-reserve effort control management and augmented reproductive benefits when small reserves are implemented. By degrading the recruitment subsidization effect to nonreserve areas from protected reserve populations, poaching results in negative externalities on yield for compliant fishermen in open areas and degrades the reproductive output and age-structure of the system. Due to the biological link between reserve and nonreserve areas, poaching in closed areas requires effort reduction in open areas to maintain management reference points. Results from the model with simple poaching fleet dynamics suggest that there are two main approaches to manage noncompliance in the marine reserve context. First is to reduce the expected benefits of poaching through enforcement and fines, and the second is to change the characteristics of the poaching fleet itself. “Community based” policies that incorporate resource users into management and enforcement may be helpful in altering the characteristics of the poaching fleet towards reducing noncompliance. The results of these simulations emphasize the importance of garnering compliance to reserve boundaries from resource users for spatial closures to be successful ocean management tools.

Author: Brooke, Sandra Title: Review of Surveillance and Enforcement of Federal Fisheries in the Southeastern U.S. Summary: Over the past several decades, there has been a significant increase in the number of marine protected areas including those that are remote from shore and cover large areas of the US Exclusive Economic Zone (EEZ). The large size of the areas and the complex assortment of regulations within them pose many challenges to policy-makers and resource managers. One of the greatest challenges is monitoring activity in these areas and enforcing regulations so that the designated areas are truly protecting the resources and are not merely ‘paper parks’. The overarching objective of this project entitled ‘Review of surveillance and enforcement of federal fisheries in the southeastern US’ was to increase the effectiveness of resource protection within the South Atlantic Fishery Management Council (SAFMC) boundaries through identification of potential improvement of monitoring and enforcement. The Marine Conservation Institute, in collaboration with the law enforcement and management agencies within the SAFMC region, has identified surveillance and enforcement challenges and suggests a series of recommendations for addressing some of these problems. Selected recommendations are listed briefly below and are described in more detail in the full report. Details: Seattle, WA: Marine Conservation Biology Institute, 2011. 47p.
