Colorful corals maybe the stars of the reef (礁石)一but they can't grow well a huge supporting cast. Fish play a load of really important roles on a coral reef. Tim Gordon, marine specialist, says some fish feed on seaweed, (clear) space for new corals. Others control whole food chains.
But when reefs (destroy), the fish flee, and the reefs suffer. So how can we get them back? One trick is playing (they) the sounds of a healthy and energetic reef.
Gordon and his (colleague) played the sounds on underwater speakers for six weeks at a test reef (build) off the coast. At the end of the trial, twice as many fish as expected were living at the energetic- sounding reef, compared to equally built reefs equipped with false speakers no speakers at all But even though it worked, isn't it sort of false advertising? Yeah, in a way it is. It is important that we think quite (careful) about how we'd use this in conservation practices. This will only be useful if we bring fish into a place it's worth bringing them to.
