This study developed a simulation framework to explore the combined effects of different measures on the performance measures of multi-sector marine fishery management. The simulation results indicated that reducing recreational discard mortality rate and implementing harvest slot regulations could have positive impacts on fishery management.
We developed a simulation framework to explore the combined effects of harvest slot regulations, reductions in recreational discard mortality rate, and alternate bycatch accountability approaches on fishery management performance measures representing a broad range of stakeholder interests in a multi-sector marine fishery. Simulation results indicated reductions in recreational discard mortality rate, alone or combined with harvest slot regulations, may result in longer recreational fishing seasons, increased recreational catch rates, reduced dead discarded biomass, and an increase in the population of reproductively valuable older fish. Based on application to Gulf of Mexico red snapper (Lutjanus campechanus), we demonstrate the trade-offs among competing management objectives and illustrate how reduced recreational discard mortality rates and allocation of catch quotas between recreational and commercial sectors based on total dead biomass versus landed catch alone can influence the efficacy of regulatory actions. We suggest increased use of simulation analyses is warranted to aid fisheries management decision making and can spur development of performance measures that better communicate trade-offs among the diverse objectives of stakeholders in multi-sector marine fisheries.
