Research Abstract

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.
