The 2020 Annual Meeting of Salmon Science Society was held online due to the COVID-19 pandemic, and two special lectures were given. Kazushi Miyashita (a professor of Hokkaido University) made a review on the current and future status of bio-logging techniques for salmon studies. He introduced various use of bio-loggers, which were well developed in Japan to investigate the migration, behavior and physiology of wild aquatic animals as well as their environments. Tetsuya Ono (a curator of Shibetsu Town Po River Historic Park) made a presentation about “a story of salmon heritage in Nemuro Strait over ten thousand years”, which was designated as a Japan Heritage in June 2020. People have been living in the coast of Nemuro Strait, eastern Hokkaido since over 10,000 years ago, and anadromous salmon are indispensable for their life and culture. He narrated a long history of connections between salmon and people in a changing frigid land to evidence their resilience.
