1 Synergistic Effects of Marine Reserves and Harvest Controls on the Abundance and Catch Dynamics of a Coral Reef Fishery  Jess K. Hopf, Geoffrey P. Jones, David H. Williamson, Sean R. Connolly  Current Biology  Volume 26, Issue 12, Pages (June 2016) DOI: /j.cub Copyright © 2016 Elsevier Ltd Terms and Conditions

2 Figure 1 Observed and Modeled Changes in Coral Trout Catch, Catch Rates, and Biomasses Observed (points and dashed lines) and modeled (dark-gray shading, which indicates the range of model outcomes for the density dependence strengths considered) changes in coral trout catch per unit effort (CPUE; tons per day and tons per license) (A), total catch (B), and biomass in fished areas (C), reserves (D), and the metapopulation (E) after the 2004 rezoning and fishery restructuring. Dashed lines are 3-year backward-moving averages, and light-gray shading captures the 95% confidence intervals on biomass estimates. Changes are relative to pre-2004 levels, and horizontal dotted lines indicate a pre-2004 business-as-usual scenario. See also Figure S1.

3 Figure 2 Modeled Changes in Coral Trout Catch, Catch Rates, and Biomasses for Various Management Scenarios Changes, relative to pre-2004, in coral trout catch per unit effort (CPUE; tons per day and tons per license) (A), total catch (B), and biomass in fished areas (C), reserves (D), and the metapopulation (E) for different modeled management scenarios: reserves (33%) and reduced fishing effort (0.5) (purple), reserves only (green), and reduced effort only (orange). In all panels, shading indicates the range of model outcomes for the density dependence strengths considered. Horizontal dotted lines indicate a pre-2004 business-as-usual scenario.

4 Figure 3 Long-Term Changes in Coral Trout Catch, Catch Rates, and Biomasses Predicted long-term changes, relative to pre-2004, in coral trout catch per unit effort (CPUE; tons per day and tons per license) (A), total catch (B), and biomass in fished areas (C), reserves (D), and the metapopulation (E) for different modeled management scenarios: reserves (33%) and reduced fishing effort (0.5) (purple), reserves only (green), and reduced effort only (orange). In all panels, shading indicates the range of model outcomes for the density dependence strengths considered. Dashed lines indicate a pre-2004 business-as-usual scenario.
