Coral reefs around the world are dying due to rising seawater temperatures, and some experts point out that natural recovery is slow due to the accelerating rate of coral whitening. While various attempts are being made to protect the suspected coral reef, researchers are trying to solve the problem by sending live coral sounds through new underwater speakers.
So far, attempts have been made to breed coral reefs that are resistant to global warming, but the new approach is unique. An experiment was conducted in which various fish were returned to the coral reef by sending sound recorded from living coral around the dying coral reef. As a result of conducting the experiment for 6 weeks, it is said that twice as many fish were gathered around the dead coral reefs, which shed the sound of living coral reefs. The gathered fish tended to sit down on the coral reefs that sounded as they were of various species, including cleaning, herbivorous, and carnivorous.
Most of the Great Barrier Reef coral reefs are at risk of extinction, according to a 2016 survey conducted by an Australian government agency. Accordingly, the research team established 33 experimental zones here from October to December 2017. An underwater speaker was placed in the center of the area to make the sound evenly sound in all directions around the speaker. In addition, the area was divided into a place where live coral reef sounds were reproduced, a place where false speakers were installed, and a place where nothing was installed.
The research team believes that this experiment could be carried out on a large scale to revive dying coral reefs around the world. The speaker says that the coral damage itself does not heal. However, for a healthy ecosystem to function, fish are important to coral reefs. Increasing the number of fish in this way can neutralize the bad factors for coral reefs found all over the world and provide a good start for natural restoration.
