"A crackling fire, a whistling tea kettle, a ticking clock — the sounds you
associate with home become so familiar that just hearing them can transport you
back there. Same with fish. Marine biologists have found that, when rebuilding
coral, playing audio recordings that were made when the reefs were healthy can
help lure their former residents back.
A recent research paper rounds up the evidence that the sounds of a healthy
reef system can attract fish, helping to bring the coral back to life. In one
2017 experiment, scientists played recordings taken at one Great Barrier Reef
site before cyclones and bleaching events devastated the area. Twice as many
fish returned to the sites where the sounds were played. “We found that we
could actually start to rebuild the reef community,” said one of the
researchers."

climate change. In parts of the Sunshine State, however, the struggle is
getting a hand from a higher power. Southerly takes a look at how Florida
