Outline of Research at the Start

マルソウダ曳縄漁を対象とした漁場監視・予測システムの開発を通じ,人工知能システムと漁業従事者が協調的に進化するための技術的基盤を確立することを目指す.そのために,1)漁師の経験や海洋物理学の知見を陽に組み込むことで予測の根拠を漁師にとって直感的に理解可能にする予測モデルの構成方法や監視インタフェースの設計,2)日々の操業中に得られるデータを効率的に活用して監視システムを持続的に成長させる方法論を,パターン認識,海況シミュレーション,水産業の専門家からなる分野横断チームにより確立する.

Outline of Final Research Achievements

This study explored fundamental technologies and the design of monitoring interfaces to enable the assessment and explanation of fishing ground conditions using meteorological and oceanographic data. Specifically, we developed a technique that accurately narrows the prediction range of optimal fishing grounds, while preventing detection omissions of actual fishing grounds. This method does not restrict predictions to previously operated sea areas, and instead utilizes unlabeled data from unexplored regions through semi-supervised learning. The effectiveness of this approach was demonstrated in the bullet tuna trolling fishery in Tosashimizu City, Kochi Prefecture. Additionally, we created a web interface to display daily updated predictions of optimal fishing grounds, which were then shared with fishermen and fisheries experts.

Academic Significance and Societal Importance of the Research Achievements

広大な未操業海域に対するデータの効率的利用は,漁獲に関するデータ収集が容易でない状況において良漁場を高精度に予測するための効果的な手段である.このように,ラベルなしデータを有効活用してシステムを効率的に構築・成長させる方法論の確立は,漁場の監視のみならず機械学習技術を社会実装するための本質的な課題であり,本研究を通じて得た予測技術およびその評価の枠組みに関する知見は広く学術的意義がある.また,漁場の高精度な監視・予測技術は,気象・海況情報を手掛かりに経験と勘に頼って意思決定を行っている現在の漁業の在り方を,データに基づく資源管理型の漁業に転換する足掛かりとなり得るもので,社会的意義も大きい.
