Recordings of fish 'whooping, croaking and growling' reveal reef coming back to life, scientists say
The team also compared the recordings they captured at the restored reef to healthy reefs nearby, and to very degraded reefs close to the same site.
"Our study shows that this restoration can really work, but it's only part of a solution that must also include rapid action on climate change and other threats to reefs worldwide.". Decades of dynamite fishing - where sticks of explosive are thrown into the reef and floating dead fish are collected from the surface - had "blown it to smithereens".
To repair the damage, that rubble is stabilised with metal frames, while small fragments of live coral are attached to those structures.Describing the recordings, Dr Lamont said the "backing track of the reef" was snapping shrimp. The species responsible for many of these unusual sounds remain a mystery. Dr Lamont said the diversity of the sounds that fish produced was "as much as the diversity of birdsong".
