Abstract This paper analyzes a unique fisheries co-management institution in Japan that has implemented two distinct sets of co-management rules within a single fishing season. The uniqueness stems from the fact that the fishing effort coordination implemented during the first half of the season and the ‘derby’ fishing during the latter half sit at the opposite ends of the spectrum in terms of cooperative behavior. The paper reveals that this rather complex co-management institution is designed to ‘fit’ the multiple ecological and socio-economic objectives that the fishermen desire to achieve. We broaden the concept of institutional fit a la Young by bringing in the notion of ‘shared understanding’ that the fishermen construct through their daily social interactions negotiating various ecological and socio-economic objectives that they wish to achieve.

实现多重社会生态制度契合：日本和谷大龙虾共同管理案例

摘要 本文分析了日本独特的渔业共同管理机构，该机构在一个捕捞季节内实施了两套不同的共同管理规则。独特性源于这样一个事实，即在本赛季前半段实施的捕捞努力协调和后半段实施的“德比”捕捞在合作行为方面处于光谱的两端。该论文表明，这个相当复杂的共同管理制度旨在“适应”渔民希望实现的多重生态和社会经济目标。
