This study was conducted to clarify migration behavior and habitat environment of the Japanese eel on the basis of survey in the North Equatorial Current where the spawning ground is located and Tone River system where the representative nursery ground is located. As the results, following matters were clarified; the leptocephali ingest particulate organic matter in the surface layer, different species of leptocephali do not take the same ingestion depth as the Japanese eel, larval transport process is largely different from it in Atlantic Ocean, and adult eels distribute preferably in the natural shore area that has high diversity of their prey organism.

通过对日本鳗鲡产卵场所在的北赤道流和代表性育苗场所在的东川水系的调查，阐明日本鳗鲡的洄游行为和栖息环境。结果表明，细头鳗在表层摄食颗粒有机物，不同种类细头鳗的摄食深度与日本鳗鲡不同，幼鳗在大西洋的运输过程与日本鳗鲡有很大差异，成年鳗鲡更倾向于分布在猎物生物多样性较高的自然海岸区。
