Researchers from Exeter and Bristol Universities, working alongside teams in Australia, found that fish are drawn to the sounds of healthy reefs and can be tempted into settling near damaged regions. The fish will help in cleaning the reef and making room for the new corals to grow, and this is how the process of ecosystem recovery starts.
Scientists say as fish clean reefs and recycle nutrients, they are able to assist in reef recovery and so enticing them to damaged areas can prove beneficial.
These speakers have played sound recordings of a healthy reef, including noise did my schooling fish, shrimp and other reef inhabitants.
"Here, using a six-week field experiment, we demonstrate that playback of healthy reef sound can increase fish settlement and retention to degraded habitat".
While they said there is more work to do, including unpicking which particular sounds might be behind the effect, whether different sounds might be needed for different reef habitats, and how sounds might affect adult fish, they said the approach has promise in speeding up reef recovery - although it should be combined with other techniques to boost the habitat.
The researchers said the recordings could be helping to lure young fish to the degraded reefs either by making fish aware that the reef is there, or by making it more likely that fish will settle there once they turn up.
The study found that twice as many fish came to the dead patches, where the loudspeakers were placed.
Scientists may have uncovered a cool way of bringing fish back to coral reefs around the world.
This increased diversity of species included in all sections of the food chain, including plant eaters, plankton eaters predators eating fish and creatures that feast on decaying plant and animal matter.
And the reefs become quiet when they start to degrade, so the fish and the shrimps disappear.
Different fish species give different roles on coral reefs, indicating that an abundant and diverse fish population is essential for maintaining a healthy ecosystem.
Researchers said acoustic enhancement is an encouraging technique for management on a regional basis.
'Whilst attracting more fish won't save coral reefs on its own, new techniques like this give us more tools in the fight to save these precious and vulnerable ecosystems, ' added Mr Gordon.
"From local management innovations to global political action, we need meaningful progress at all levels to paint a better future for reefs worldwide".
The full findings of the study were published in the journal Nature Communications.
