Co-management is now established as a mainstream approach to small-scale fisheries management across the developing world. A comprehensive review of 204 potential cases reveals a lack of impact assessments of fisheries co-management. This study reports on a meta-analysis of the impact of fisheries co-management in developing countries in 90 sites across 29 case-studies. The top five most frequently measured process indicators are participation, influence, rule compliance, control over resources, and conflict. The top five most frequently measured outcome indicators are access to resources, resource well-being, fishery yield, household well-being, and household income. To deal with the diversity of the 52 indicators measured and the different ways these data are collected and analysed, we apply a coding system to capture change over time. The results of the meta-analysis suggest that, overall fisheries co-management delivers benefits to end-users through improvements in key process and outcome indicators. However, the dataset as a whole is constituted primarily of data from the Philippines. When we exclude this body of work, few generalisations can be made about the impact of fisheries co-management. The lack of comparative data suitable for impact assessment and the difficulties in comparing data and generalising across countries and regions reiterates calls in other fields for more systematic approaches to understanding and evaluating governance frameworks.
渔业共同管理现已成为发展中国家小规模渔业管理的主流方法。对 204 个潜在案例进行的全面审查显示，渔业共同管理缺乏影响评估。本研究对 29 项案例研究中的 90 个地点的发展中国家渔业共同管理的影响进行了元分析。测量频次最高的五个过程指标分别是参与度、影响力、规则遵守情况、对资源的控制和冲突。测量频次最高的五个结果指标分别是资源获取、资源健康、渔业产量、家庭福祉和家庭收入。为了处理 52 个测量指标的多样性以及这些数据的不同收集和分析方式，我们应用编码系统来捕捉随时间的变化。元分析的结果表明，渔业共同管理通过改善关键过程和结果指标，为最终用户带来了益处。然而，整个数据集主要由菲律宾的数据构成。当我们排除这些工作时，就很难对渔业共同管理的影响做出一般性的概括。缺乏适合影响评估的比较数据以及在国家和地区之间比较数据和推广的困难，再次呼吁在其他领域采用更系统的方法来理解和评估治理框架。
