Eel Swimming Experiment Featured in the Tōshin Journal and Shinshū Minpō

An article titled “Institute for Freshwater Biology, Nagano University – Observing Mid- to Long-Term Effects of Eel Swimming: Joint Study with Shinshu University Faculty of Engineering” appeared in the Tōshin Journal on September 2, 2025. A follow-up feature titled “Nagano University’s Institute for Freshwater Biology Announces Two Studies on Eels – Flow Chamber Experiments and Swimming Analysis” was published in the Shinshū Minpō on September 6, 2025.

Both articles introduced the joint research project between the Institute for Freshwater Biology, Nagano University, and the Faculty of Engineering, Shinshu University, focusing on experiments observing the mid- to long-term effects of swimming behavior and tag attachment in eels. The study aims to understand eel behavior and migratory adaptation, as well as to improve tagging and tracking technologies, combining hydrodynamic analysis and device design by the Faculty of Engineering with behavioral observation and data analysis by the Institute for Freshwater Biology.

These collaborative efforts provide fundamental insights into quantifying physiological impacts and refining tagging techniques, contributing to the sustainable use of eel resources and the conservation of aquatic ecosystems.
