Monitoring the Japanese Eel: A Biodiversity Experience at Hinuma Wetland

On August 23rd, 2025, the Pal System Ibaraki Tochigi Cooperative will host a monitoring survey aimed at restoring the Japanese eel population at the Hinuma Wetland. The event will take place from 10:30 AM to 3:00 PM at the Oyasawa Park Campground in Ibaraki Town. This initiative ties into the Ramsar Convention's commitment to conserving important wetland biodiversity.

The survey focuses on observing endangered Japanese eels and various aquatic life through artificial eel shelters known as stone cages. These stone cages, designed for monitoring, were first introduced in the region under the guidance of Dr. Noritaka Nozoka, a special professor at Kyushu University. Dr. Nozoka's collaboration with local fishermen and governmental bodies marked a significant step in eel resource recovery in the area.

Participant Engagement

Approximately 50 participants, including families and community members, will join the monitoring efforts alongside Dr. Nozoka to examine the ecosystem within the stone cages. The participants will identify and count the different species they find, while special attention will be paid to any eels discovered. Measurements of their length, girth, and weight will be taken. Additionally, previous surveys have involved implanting PIT tags in some eels to monitor their health and growth, contributing vital data for ongoing conservation efforts.

In the afternoon, the event will shift to the Hinuma Waterfowl and Wetland Center, where Dr. Nozoka will share his research on the habitats and ecological traits of the Japanese eel. Attendees can also enjoy exhibits detailing the relationship between Hinuma's nature and its human interactions, featuring live specimens and displays.

Protecting Cultural Heritage Through Consumption

Since being designated as an endangered species in 2013, the Pal System has actively supported eel resource recovery in collaboration with the Osumi District Aquaculture Association from Kagoshima. Together, they established the Osumi Eel Resource Recovery Council, which focuses on research, fundraising, and education to protect Japan’s culinary heritage. The organization has invested in monitoring efforts at various river sites in Kagoshima, yielding promising results that have now expanded to Hinuma.

Celebrating Ramsar Wetland Biodiversity

Recognized as an important wetland by the Ramsar Convention in 2015, Hinuma offers a unique blend of freshwater and seawater, supporting diverse wildlife including the Japanese eel, crab species, and unique dragonflies, making it a cherished ecosystem. The collective commitment from local citizens, partners, and the cooperative aims to maintain and restore this precious environment, promoting sustainable resource use and conservation education for future generations.

Pal System has garnered accolades for its relentless dedication to environmental stewardship, including a recent award from the Hinuma Cleanup Network for water quality improvement efforts.

As we look ahead to the International Year of Cooperative Organizations in 2025, Pal System Ibaraki Tochigi will continue fostering rich partnerships to ensure a thriving ecosystem for generations to come, preserving not just wildlife but also the cultural legacies tied to these unique species.

In summary, this survey provides a vital opportunity not only to monitor and restore the eel population but also to involve the community in understanding and supporting biodiversity initiatives.
