Outline of Final Research Achievements |
We investigated the current status of data on eel resource use and natural resource volume in Japan. With regard to the amount of natural resources, systematic data collection has not been carried out, and the current situation of consuming endangered species in the form of incomplete aquaculture with lack of scientific information has become clear. With regard to social resource flows of eel, the characteristics of the input / output structure were clarified by virtually correlating the “eel industry” using the inland fishery and aquaculture industry of input-output data. Furthermore, in order to analyze the spillover effect to related industries, the influence on upstream industry and downstream industry was estimated by input-output analysis. The resource flow model constructed in this study makes it possible to analyze the impact on the eel industry and related industries if natural resource inputs are clarified.

Academic Significance and Societal Importance of the Research Achievements |
ウナギ資源はわが国の食において広く利用されており,近年の不漁から注目度が高いにもかかわらず,社会的フローという視点での分析はあまり実施されていない.本研究ではウナギ産業という視点からの分析により,投入・産出構造や関連産業の波及効果を明らかにした.データ不足によりウナギ産業自体の詳細な分析は不十分であるが,将来データ整備が実現すれば,本モデルを用いることで実証的な分析を行うことができる.さらに天然資源量の情報が得られれば,社会的利用との関連性を考慮して,より精緻な資源フローについて分析することが可能となる.このような分析を行うことで,持続可能なウナギ資源の適切な利用について検討することができる.
