Research Outline

Marine fishery resources are important renewable resources, and the choices of fishing gear and method affect their sustainable use. With increasing emphasis on ecosystem balance, fisheries aim not only to improve target catch but also to protect non-target species. For example, in tuna longline fisheries, environmental conditions and gear design affect sinking performance. Hook depth influences catch composition, while sinking speed affects seabird bycatch. Therefore, appropriate gear design is needed to maintain tuna catch while reducing bycatch, contributing to responsible fisheries.

My research focuses on fishing gear and methods, aiming to support sustainable fisheries. I have conducted numerical simulations of gear sinking behavior using the finite element method, combined with field observations using acceleration loggers. By integrating empirical data and simulations, I optimize gear configurations and enhance understanding of fish behavior and fishing processes through visualization. In addition, I analyze fishery resources by integrating operational data with spatiotemporal and satellite datasets, contributing to improved understanding of fishery dynamics.
