Coral Okinawa (NPO)

Encouraging the diversification of coral groups in the seas around the Okinawa Islands using coral larvae implantation tools

Activity grant

Project Description

Coral groups in the seas around the Okinawa Islands have been declining due to bleaching since 1998. This project aims to restore ecosystems by introducing diversity into these coral groups. Coral larvae will be implanted into habitats around Aka Island in the Kerama Islands, which support a diverse range of coral, using an implantation tool and timed to match when all coral species release their eggs. This coral will be cultivated for one year after which it will be transplanted to the seas around the Okinawa Islands. The transplantation will be conducted under various conditions and will be monitored. Seminars on the project will also be held.
