In the early 1990s, Heterocapsa-red tide, brought on by the latest type of pearl oyster killer, plankton suddenly occurred in Ago Bay, Mie Prefecture, known as the birthplace of cultured pearls. As a countermeasure for this terrible phenomenon, the Mikimoto Pearl Research Laboratory co-developed the world’s first organic-based marine environment monitoring system, “Kai-Lingual (‘Kai’ means ‘shellfish’ in Japanese.),” using an original device to measure the valve movement of bivalve shellfish.　Mikimoto will continue to protect the ocean that grows its pearls and live in harmony with nature.
