Sydney (Reuters) – Australia’s first Coral IVF study coral population in Australia in 2016 will not only survive the recent bleaching phenomenon, but will also breed and spawn next year. Researchers say there is.
“I’m really excited,” said Peter Harrison, director of the Center for Marine Ecology Research at Southern Cross University. He led the development of larval recovery techniques, including collecting coral sperm and eggs during annual mass production eggs on coral reefs.
Scientists cultivate the larvae in a specially designed enclosure for about a week and then distribute the larvae to some of the reefs that have been damaged by bleaching and need live coral.
Harrison’s team, working with the Great Barrier Reef Foundation, first used tactics in 2016, just off Heron Island. There, over 60 corals are becoming the first re-established breeding populations on coral reefs through coral IVF.
“This proves that larval recovery techniques work as we expected and can grow very large corals from small microscopic larvae within just a few years,” Harrison said in December. I said after visiting the recovery site in early.
Corals vary in diameter from just a few centimeters to the size of a dinner plate and were healthy despite the bleaching event that hit Heron Island in March.
According to scientists, March bleaching was the most widespread coral reef ever and the third in five years.
Bleaching occurs when hotter water destroys the algae that the corals are eating and whitens them.
A recent study by James Cook University raises concerns that coral reefs have lost more than half of their reefs in the last three decades and cannot recover from massive bleaching events.
The Great Barrier Reef is 2,300 km (1,429 miles) down the northeastern coast of Australia, which spans half the area of Texas. It was listed as a World Heritage Site by UNESCO in 1981 as the largest and most spectacular coral reef ecosystem on the planet.
