Tracking Coral Sex Life to Save Them

In Mauritius, an NGO is monitoring the sex life of corals to save them. Every October, Blue Bay takes on a pinkish hue due to corals releasing millions of eggs and sperm in a synchronized spawning event crucial for their survival.

Scientists are now relying on this natural phenomenon to save corals affected by climate change. A team of researchers is set to collect millions of larvae from Blue Bay this October as part of a large project to restore corals through sexual propagation in the Western Indian Ocean.

"The project really starts from scratch,"

says Gaëlle Quéré, marine scientist and project lead at Secore International, a partner in the Mauritius project launched in 2024.
