Marine biologists in southeast Asia and Australia are harvesting hundreds of thousands of coral spawn with a view to regenerating the world’s coral reefs, including the Great Barrier Reef (GBR), a UNESCO World Heritage Site.
Professor Peter Harrison from Southern Cross University in New South Wales, Australia collects coral spawn off the coast of Heron Island on the GBR, matures it in tanks and then transplants it later.
“It’s really exciting, this essentially is the rebirth of the reef,” Professor Harrison said, as cited by ABC News. “We can grow these corals from microscopic larvae to dinner-plate size, breeding corals in just three years.”
“It’s a new way of looking at the problem and it’s probably the only hope for the future in terms of larger-scale restoration using hundreds of millions of coral larvae.”
