Highlights

Natural resource managers and policy makers are faced with how to sustain resources used in a coupled social-ecological system (Schlüter et al 2012, Guerrero et al 2018)
By linking a food web model with a fisher behavior model, we have demonstrated a social-ecological method that could be useful for testing social responses to environmental and anthropogenic perturbations
We have shown that including a human dimensions component can lead to large differences in model-predicted values of ecological variables, i.e. fish biomass

Summary

Introduction

Natural resource managers and policy makers are faced with how to sustain resources used in a coupled social-ecological system (Schlüter et al 2012, Guerrero et al 2018) These linked systems provide a variety of ecosystem services through a combination of natural components and social, economic, political, and cultural factors (Boyd and Banzhaf 2007). Fisheries science has strived to incorporate an understanding of the physical, biological, and ecological factors of an ecosystem, including the use of food web models that capture inter-species dynamics. Ecopath with Ecosim (EwE) is a food web model that simulates energy flow and biomass of organisms (Polovina 1984, Christensen and Pauly 1992). When menhaden were fished at maximum sustainable yield, striped bass
