| Outline of Final Research Achievements |
Because the environmental impact assessment will be indispensable for large-scale ocean developments, the evaluation methods for them should be developed. The fish behavioral model was improved to assess the impacts on fishery resources which is particularly important among ecosystem changes due to the ocean and coastal developments around Japan. An end-to-end ecosystem model was also developed, which comprehensively deal with lower ecosystems including nutrient dynamics and higher ecosystems including fish, taking into consideration the anthropogenic impacts on them.

| Academic Significance and Societal Importance of the Research Achievements |
沿岸海域の複雑な環境要因とリンクした魚類の行動をモデル化し、構造物の設置や漁獲圧の変化などの外的環境変動に対応した時空間解像度をもつ沿岸性魚類の動態モデルは、海洋開発の環境影響評価に有効であると考えられる。また、低次生態系から高次生態系までを統合的に扱うEnd-to-Endモデルは、水質、物質循環、漁業資源等の多面的な評価に適用可能であり、海洋開発と漁業との協調や生態系保全に対して有益な情報を提供できると考えられる。
