The use of moored Fish Aggregating Devices (FADs) in small-scale fisheries is a potential solution to food security concerns, economic development needs, and the overexploitation of nearshore coastal fisheries in the Eastern Caribbean. However, moored FADs also generate novel and largely unstudied governance challenges involving (1) the provisioning of FADs, (2) fisheries resource appropriation, (3) human wellbeing, and (4) food web impacts. We examine the relative performance of three governance scenarios to address these challenges: private-individual, community-based, and top-down governance. We construct a qualitative network model (QNM) of the fishery based on semi-structured interviews (n = 60) with fishers and fisheries managers, established food web and economic models, and expert knowledge. We simulate the social-ecological impacts of the three governance scenarios. The models suggest that community-based and top-down governance scenarios result in low levels of conflict, but provide limited incentives to develop and maintain moored FADs. The private-individual governance scenario tends to increase conflict and incentives for monitoring FADs, but has no impact on incentives for maintaining and deploying FADs.

管理东加勒比海的近海鱼类聚集设备：使用定性网络模型探索权衡。

在小规模渔业中使用系泊集鱼装置 (FAD) 是解决东加勒比地区粮食安全问题、经济发展需求和近岸沿海渔业过度开发的潜在解决方案。然而，停泊的 FADs 也产生了新的且很大程度上未经研究的治理挑战，涉及 (1) FADs 的供应，(2) 渔业资源占用，(3) 人类福祉，以及 (4) 食物网影响。我们研究了应对这些挑战的三种治理方案的相对表现：私人个体、基于社区和自上而下的治理。我们基于对渔民和渔业管理者的半结构化访谈（n = 60）、建立的食物网和经济模型以及专家知识，构建了渔业的定性网络模型（QNM）。我们模拟了三种治理情景的社会生态影响。这些模型表明，基于社区和自上而下的治理方案导致冲突程度较低，但对开发和维护停泊的 FAD 提供的激励有限。私人个体治理方案往往会增加监控 FAD 的冲突和激励，但对维护和部署 FAD 的激励没有影响。
