Coral larvae more likely to settle on degraded reefs bathed in marine soundscapes, Caribbean study shows

Underwater speakers that broadcast the hustle and bustle of thriving coral could bring life back to more damaged and degraded reefs that are in danger of becoming ocean graveyards, researchers say.

Scientists working off the US Virgin Islands in the Caribbean found that coral larvae were up to seven times more likely to settle at a struggling reef where they played recordings of the snaps, groans, grunts and scratches that form the symphony of a healthy ecosystem.

“We’re hoping this may be something we can combine with other efforts to put the good stuff back on the reef,” said Nadège Aoki at the Woods Hole Oceanographic Institution in Massachusetts. “You could leave a speaker out for a certain amount of time and it could be attracting not just coral larvae but fish back to the reef.”
