Abstract Ecosystem approaches to fisheries management (EAF) are increasingly relevant for intergovernmental fisheries policies, national management plans, and seafood certification guidelines. To aid in integration of EAF in tropical artisanal fisheries, this study evaluates the potential ecosystem impacts of four distinct fisheries (kelp forest, sandy shore, pelagic, and reef ecosystems) in Mexico, using quantitative trophic models and a comparable network developed using fishers’ traditional knowledge. Notably, the fishers’ model was actually more complex than science-based models and could be a highly useful baseline for subsequent collaborative efforts for ecosystembased management. At current fishing levels, these fisheries are not expected to have significant ecosystem impacts, though we identify species that could be potentially impacted if fishing effort were to considerably increase and that should be monitored. Explicitly considering ecological interactions—whether or not this can be fully integrated into reference points—in co-managed fisheries can help prioritize monitoring and management measures, supporting ecologically sustainable fisheries and the social and economic objectives of artisanal fishers.

通过生态系统建模和传统渔民知识评估数据有限的手工渔业对生态系统的影响

摘要 渔业管理（EAF）的生态系统方法与政府间渔业政策、国家管理计划和海产品认证指南越来越相关。为了帮助将 EAF 纳入热带手工渔业，本研究使用定量营养模型和使用渔民开发的可比网络，评估了墨西哥四种不同渔业（海带森林、沙滩、远洋和珊瑚礁生态系统）的潜在生态系统影响。传统知识。值得注意的是，渔民模型实际上比基于科学的模型更复杂，并且可以成为后续基于生态系统管理的协作努力的非常有用的基线。在目前的捕捞水平下，这些渔业预计不会对生态系统产生重大影响，尽管我们确定了如果捕捞努力量大幅增加可能会受到影响的物种，并且应该对其进行监测。在共同管理渔业中明确考虑生态相互作用——无论这是否可以完全纳入参考点——有助于优先监测和管理措施，支持生态可持续渔业以及个体渔民的社会和经济目标。
