Reef Conservation Activities
Casio Coral Field
In collaboration with various environmental protection groups, Casio has been promoting its “Love The Sea And The Earth” project to support the activities of the groups. In 2018, Casio began providing support for Aqua Planet, an NPO that preserves coral, which is chaired by actress Ritsuko Tanaka. In January, the Casio coral field was established in the seas of Ishigaki, Okinawa Prefecture, and 200 coral “seedlings” were planted with the objective for them to reproduce in three years’ time. Casio carried out this activity as an official supporter of the International Year of the Reef 2018 appointed by the Ministry of the Environment.
The Casio coral field lies to the south of Ishigakijima island, Okinawa Prefecture in shallow seas about 4 meters deep at high tide. The coral coexists with a phytoplankton called zooxanthella, and 200 coral seedlings from more than seven resilient varieties, including Acropora Copiosa Nemenzo in the genus Acropora of the family Acroporidae, were planted.
These coral seedlings were ones that had been newly collected with permission and divided seedlings cultivated in other coral fields.

With a water temperature of 23.6°C, no major changes compared with February could be observed in the coral at a glance, but, looking carefully, the soft body of the coral had begun to cover the stainless steel wire. It was confirmed that the coral was steadily becoming established.
