Outline of Final Research Achievements

This study examined the multispecies fishery in Japan and its diverse distribution, highlighting its contributions to operational stability and resilience improvement. The approach utilized fishery portfolios at both the prefecture and fishery cooperative levels, integrating detailed capture and market data to demonstrate the diversity of catch volume and value. It has been demonstrated that portfolio fishing in multispecies fisheries reduces risk and stabilizes operations in the face of resource and fish price fluctuations. This reveals the potential for novel fishery management and marine policy measures through multispecies fishing portfolios, as well as the disadvantages of limiting the capture and landing of specific species in multispecies fisheries.

Academic Significance and Societal Importance of the Research Achievements

本研究は、日本の漁業の在り方を多魚種漁獲ポートフォリオとして定義することで、新たな日本漁業への解析手法とそれに基づく漁業経営および水産政策施策の可能性を示した。2023年三月末に総理官邸より本研究成果を世界に発信するための記事と動画が, 「Japan‘s Unknown Stable and Waste-Free Fishery」として発表された。ポートフォリオ漁業により、震災すら乗り越えた日本漁業の独自性と可能性を世界に、また、日本の政策としてポートフォリオ漁業をすすめてゆく起点をつくった。
