As the Great Barrier Reef becomes more and more affected by coral bleaching, researchers are testing a way to add new coral to the reef. This involves taking the sperm and eggs of the coral reef, breeding them, and then returning them to the reef once they have turned into larvae.

This so far has proved effective in 100 coral larvae that are growing successfully:

The lead project researcher and Southern Cross University professor Peter Harrison, who discovered mass coral spawning in the 1980s, says the “results are very promising”.

“The success of this new research not only applies to the Great Barrier Reef, but has potential global significance,” Harrison said.

The Great Barrier Reef Foundation managing director, Anna Marsden, said the research is an important step for the reef, but one that should not lessen the strong action needed against climate change.

“There is much more to be done, but this is definitely a great leap forward for the reef, and for the restoration and repair of reefs worldwide,” she said.
