Scientists’ experiment is ‘beacon of hope’ for coral reefs on brink of global collapse

Recordings of healthy fish are being transmitted to attract heat-tolerant larvae back to degraded reefs in the Maldives

An underwater experiment to restore coral reefs using a combination of coral IVF" and recordings of fish noises could offer a beacon of hope" to scientists who fear the fragile ecosystem is on the brink of collapse.

The experiment - a global collaboration between two teams of scientists who developed their innovative coral-saving techniques independently - has the potential to significantly increase the likelihood that coral will repopulate degraded reefs, they claim.
