The Institute of Freshwater Biology is conducting a survey of Japanese eel spawning migration using pop-up satellite tags as part of a project to analyze the mechanisms of change in international fishery resources. In this project, we are improving a new type of satellite tag for the world's smallest eel and conducting field surveys in cooperation with Little Leonardo and the Faculty of Engineering at Shinshu University. This time, on August 24, 2021, we went to the coast of Shizuoka to conduct a preliminary experiment to check the pressure resistance of the satellite tag. The tag, which was programmed to detach after three days, sunk to a depth of 1,000 meters then popped up on the sea surface as planned.
