Abstract Social networks have been and remain important in Oceania for building and maintaining social-ecological resilience. However, there is little quantitative information on the role of fish and fishing in resource sharing networks and how networks may be impacted by socioeconomic and environmental changes, which is critical information for developing culturally appropriate fisheries management strategies. To better understand this gap, we conducted social network analysis of sharing networks in 18 villages in Fiji across a socioeconomic gradient. Villages formed two clusters based on network characteristics: villages on the main island had less cohesive networks with more cash and purchased good sharing, while villages located on other islands had more cohesive networks with a greater proportion of natural resource sharing. Metrics of network cohesion were positively correlated with mean household fishing frequency and negatively correlated with measures of material wealth. Fishers reported sharing the largest estimated catch from gillnets and night spearfishing. Given concerns about the sustainability of these fishing practices, we suggest methods for regulating these gears while maintaining fish sharing customs. This study shows how social network analysis can be conducted to better understand sharing networks to support natural resource management.

调查鱼类和捕鱼在共享网络中的作用，以建立珊瑚礁社会生态系统的复原力

摘要 社交网络在大洋洲对于建立和维持社会生态复原力一直并且仍然很重要。然而，关于鱼类和渔业在资源共享网络中的作用以及网络如何受到社会经济和环境变化影响的定量信息很少，这些信息对于制定适合文化的渔业管理战略至关重要。为了更好地理解这一差距，我们对斐济 18 个村庄跨越社会经济梯度的共享网络进行了社交网络分析。村庄根据网络特征形成两个集群：主岛上的村庄网络凝聚力较小，现金较多，购买商品共享，而位于其他岛屿的村庄网络凝聚力更强，自然资源共享比例更大。网络凝聚力指标与平均家庭捕鱼频率呈正相关，与物质财富指标呈负相关。渔民报告分享了刺网和夜间鱼叉捕鱼的最大估计渔获量。考虑到对这些捕捞方式的可持续性的担忧，我们建议在保持鱼类共享习惯的同时管理这些渔具的方法。本研究展示了如何进行社交网络分析以更好地了解共享网络以支持自然资源管理。我们建议在保持鱼类共享习惯的同时管理这些渔具的方法。本研究展示了如何进行社交网络分析以更好地了解共享网络以支持自然资源管理。我们建议在保持鱼类共享习惯的同时管理这些渔具的方法。本研究展示了如何进行社交网络分析以更好地了解共享网络以支持自然资源管理。
