“…Consequently, we chose all three as recreational fishing objectives for evaluation. For performance metrics, we chose to measure changes in the median of recreational catch, the proportion of legal-sized fish in the estimated population, and the exploitation rate as a proxy for season length (Bohaboy et al, 2022). Reducing discards was an additional objective that both a commercial and recreational fisher cited but did not rank in response to Question 2.…”

Management strategy evaluation (MSE) has become a more common tool for engaging stakeholders in fisheries management, and stakeholder participation in MSE is increasingly recognized as a vital component of the process. The participation of stakeholders, specifically fishers, in MSE is of particular importance because they often possess intimate knowledge of the socio-ecological management system that MSE seeks to model. When the resources to conduct a “full” MSE with direct fisher involvement are unavailable, MSEs are sometimes conducted by desk-based analysts with no fisher engagement. We propose an intermediate framework in which information collected from semi-structured interviews is used to inform a “desk-based” MSE. We demonstrate that semi-structured interviews with commercial and recreational fishers can elicit some of the same kinds of information that fishers provide during direct participation in MSE. We conducted 30 semi-structured interviews with commercial and recreational fishers from the Southeast United States participating in either Atlantic cobia (Rachycentron canadum) or black sea bass (Centropristis striata) fisheries. We collected primarily qualitative and some quantitative information about preferred conceptual objectives and management measures, and how their fishing behavior has changed in response to past management action. Commercial fishers generally preferred conceptual objectives and management measures that align with traditional MSY-based fisheries management, while recreational fishers’ responses were substantially more heterogeneous, indicating a more diverse range of desired objectives and preferred management measures. We synthesized this information to develop a suite of management procedures that employ a range of fishing mortality-based constant-catch harvest control rules and size-based management measures for simulation testing against preferred objectives by sector. We demonstrate that integrating information from semi-structured interviews with MSE in this way offers a cost-effective alternative intermediate approach to fisher participation in MSE when direct participation is not possible.

“…Much like our study, Bohaboy et al. (2022) simulated various management approaches for Red Snapper as part of a multisector fishery. Although their focus was on Red Snapper in the Gulf of Mexico and the simulation framework was quite different from ours, the two studies share some implications for management.…”

“…Simulation modeling of potential management measures has a rich history in fisheries (e.g., Johnson 1995;Cooke 1999;Mapstone et al 2008;Butterworth et al 2010;McQuaw et al 2021). More than half a century ago, Paulik (1969) predicted that simulation models would become commonplace in the resource management agency of the future, and more recently, Bohaboy et al (2022) recommended the increased use of simulation analyses to inform fishery managers.

“…This rationale for delay can be more pronounced when the composition of management panels is dominated by stakeholders (Okey 2003). To inform those panels, regardless of composition, simulation-based analyses can provide an objective comparison of the benefits and risks of potential management measures (e.g., Cooke 1999;Mapstone et al 2008;McQuaw et al 2021;Bohaboy et al 2022).…”

ObjectiveRed Snapper Lutjanus campechanus is an iconic species in the southeast U.S. Atlantic Ocean, sought by both commercial and recreational fleets. Five stock assessments over the past quarter century have shown Red Snapper to be experiencing overfishing. Highly restricted landings since 2010 have been insufficient to end overfishing because fishing effort is not species specific but rather applies generally to a complex of reef‐associated species. Consequently, Red Snapper are discarded as bycatch when regulations prohibit their retention, and many of the discarded fish die from hook injury, barotrauma, or depredation.MethodsHere we developed a spatial population model of Red Snapper and the multispecies fishery that captures them in the southeast U.S. Atlantic. We then simulated and compared 25 different management measures that fall broadly into the categories of gear modifications, discard mortality mitigation, size limits, spatial approaches, or temporal approaches. Criteria for comparison address the management goals of decreasing dead discards, rebuilding the age structure, and increasing landings and spawning biomass.ResultWe found that the most effective measures reduced fishing effort, either temporally or spatially, and that benefits could largely be obtained by focusing on the recreational fleet. Discard mortality mitigation (e.g., through use of descender devices) displayed a wide range in effectiveness depending on plausible levels of mortality reduction, but it addressed all management goals and in practice could be paired with other measures. A measure with restricted recreational effort combined with full retention of all fish caught showed the greatest potential to simultaneously rebuild the stock, increase landings, and eliminate dead discards.ConclusionTo end overfishing of Red Snapper as required by law, resource managers should reconsider the policy of unrestricted effort of the private recreational fleet to this multispecies fishery. The benefits of restricted effort would include increased catch rates, larger landed fish, and fewer dead discards.
