Lab-Bred Corals Offer New Hope for Reef Restoration

Seychelles has recorded the first successful coral spawning at a new land-based breeding laboratory, producing thousands of juvenile corals to strengthen reef restoration in the Indian Ocean.

“Witnessing our first successful spawning event at the lab has been incredibly rewarding,” said Nirmal Shah, Chief Executive of Nature Seychelles. “Coral offspring have not only survived but settled and grown, turning a spawning event into a pipeline of living reef builders.”

The laboratory on Praslin Island produced about 800,000 coral embryos from 14 parent colonies, with roughly 65,000 juveniles successfully settling during the first breeding cycle. Unlike traditional coral gardening, which relies on cloning fragments, the facility uses controlled sexual reproduction to create genetically diverse corals that are better able to withstand warming seas and bleaching events. Researchers plan to outplant the young corals onto nearby reefs and expand breeding efforts to support long-term ecosystem recovery.
