Ecosystem-based fisheries management has emerged as a new approach to fisheries management, broadening the scope beyond the traditional single-fishery management paradigm. A broader scope, however, necessitates additional information on system components and new methodologies to design management approaches that consider ecological, human, and human-ecological connections. Although there have been calls for increased consideration of system linkages and ecological and socioeconomic components and outcomes, relatively little work has been done to-date. In this paper we develop a dynamic, integrated, human-ecological model. It incorporates ecological connectivity between species in the form of a foodweb, a human system comprised of fishers who choose among multiple fisheries to fish in subject to management program design, and fisher harvest linking the ecological and human components. We identify the human and ecological conditions under which gains from management approaches that account for the system connectivity relative to traditional single-fishery management policies are greatest, providing insight into when the returns to using more complex models to design fisheries management policies will be greatest.
