Scientists lured fish back to the Great Barrier Reef, making it sound alive




Earth's coral reefs die and need our help. Either we have to come up with a magical way to get fish to return and spawn, or convince the politicians and business leaders of the planet to take the climate crisis seriously. And since science can not make the impossible, a team of international researchers has tackled the problem of persuading Pisces to make the Two-Finned Beast in the hollow bones of a coral cemetery.

The team believed that dead coral reefs did not sound or smell like lively coral reefs. To test this hypothesis, they picked up sounds from flourishing areas of the Great Barrier Reef and played them over loudspeakers in areas that were dead and dying. Amazingly, they found that 50 percent more fish returned to dying areas, which sounded healthy compared to similar areas without audio feed.

Steve Simpson, a professor at the University of Exeter and senior author of Team Paper, said:

Reefs become eerily silent when degraded as the shrimp and fish disappear, but through the use of speakers to this restore lost soundscape, we can attract young fish again.

About 89 percent of the Great Barrier Reef is dead or dies. Countless species of "reef fish" have fled the ecosystem decay and others have taken the nutrients vital to the survival of the coral. While attracting fish does not completely solve the problem or save reefs from increasing climate change, it can boost regeneration and, in essence, help them return from the edge. Because corals need fish piss.

Our gills friends are like vitamin filters for coral reefs. They pee and puke and shed dandruff and die doing all sorts of things that allow giant reefs to absorb nutrients. In return, we can all live.

As things stand, the coral reefs of the world are doomed to extinction without these fish and their peephole. That's a very bad thing. As marine scientist Michael Crosby told Business Insider last year, reef health is directly related to ours:

Do you like to breathe? It is estimated that up to 80 percent of the oxygen you are inhaling comes from the ocean. It does not come from the country. In order for you to continue breathing, you must have a healthy ocean.

And a healthy ocean means you have a lot of crazy fish around to make babies and pee everywhere.
