Recorded sounds lure fish back to Great Barrier Reef
Healthy Coral Reef is a noisy placed the constant crackling sound. That's the sound of snapping shrimp. Then on top of that hopes grunts growls, trumpeting sounds weeping sounds. And these generally made by fish that are communicating with each other, but Steve Simpson of the university, of Exeter in the UK says after damaging coral bleaching events, which are growing more common as oceans warm that soundscape changes. When his team visited part of the Great Barrier Reef after a major bleaching event, really a shock. We found that the reefer gone quiet. It was assigned that many sea creatures had left the area. Now, Simpson team is using sound to draw some of that life back. At eleven locations in the Great Barrier Reef they played recording a healthy reap ecosystem. After six weeks compared the fish life in those places with that and other areas. They found that twice. As many fish had returned to the audio enrich sites. So Simpson says as restoration managers repair damaged corals found recordings can help jump start the process of restoring vibrant and noisy coral, reef ecosystems.
