Broadcasting sounds of healthy coral reefs encourages coral larvae growth, study shows

Coral reefs worldwide are in trouble. These ecosystems support a billion people and more than a quarter of marine species. Still, many have been damaged by unsustainable fishing and tourism, coastal construction, nutrient runoff, and climate change. Now, researchers have shown that broadcasting the sounds of healthy reefs is a way to encourage larval corals to repopulate degraded sites and help revitalize them.
