Shikoku Aquarium (located in Utazu, Kagawa Prefecture) has begun showcasing cutting-edge research on artificial fish reefs designed to enrich the Seto Inland Sea, starting Saturday, May 2, 2026.
This project is conducted under a comprehensive collaboration agreement with Kagawa University. Working with the Suenaga Laboratory of the Faculty of Engineering and Design, the aquarium is exhibiting small-scale models of artificial fish reefs. Future plans include the exhibition of algae attached to reefs actually deployed in the sea and the installation of these reefs in local waters.
Issues such as the depletion of seaweed beds and declining fish catches have become prominent in the Seto Inland Sea. The research led by the Suenaga Laboratory is gaining attention for its effectiveness in promoting seaweed growth and creating habitats for marine life, contributing significantly to local 'Satoumi Restoration' and 'Blue Carbon' initiatives. Visitors are encouraged to explore this advanced 'sea-cultivation technology,' which is essential for the future of the Seto Inland Sea.
