(AFP) – Scientists launched the largest attempt & # 39; regeneration coral on the Great quarry in danger Reef by collecting millions of & # 39; eggs and sperm creatures during their annual generation.

The researchers said Wednesday they plan to grow coral larvae from – rotten eggs and rritornahom to areas – reef that have been deleted affected by climate coral bleaching.

"This is the first time that the entire breeding process and the large-scale larval payment will be made directly on the reefs on the Great Barrier Reef, "Said Peter Harrison & # 39; Southern Cross University, one of the project leaders.

"Our team will restore hundreds & # 39; square meters in order to reach square kilometers in the future, scale not attempted before", said in & # 39; statement.

Launch & # 39; "Project & # 39; Restoration & # 39; larval" was f & # 39; timely to coincide with the annual coral spawn on – reef, Which began earlier this week and will last only about 48 to 72 hours.

Coral over large periods & # 39; 2,300 kilometers (1,400 miles) reef killed by & # 39; rising sea temperatures associated climate Changes, leaving the skeletal remains in a process known as coral bleaching.

The – north & # 39; reef suffered two successive years of & # 39; severe bleaching in 2016 and 2017, and raised fears could & # 39; suffered irreparable damage.

Harrison and his colleagues are hopeful that the project & # 39; re putting their can & # 39; helps restore & # 39; behind the trend, but he showed that effort alone will not be enough to save the reef.

"climate action is the only way you can & # 39; ensure coral reefs can & # 39; lives in the future, "he said.

"Our approach reef The restoration aims to buy time coral populations to survive and evolve unless emissions are limited and our climate stabilizes. "

Scientists hope to coral survived in bleaching, have more tolerance for rising temperatures to population & # 39; breeding produced by generating & # 39; this year grows coral more able to survive in future bleaching events.

The researchers, who also include experts from James Cook University and the University of Technology & # 39; Sydney (UTS), said the project innovation & # 39; coral larvae plus & # 39; microalgae. Both live in & # 39; symbiosis on the reef.

"So we are aiming to move & # 39; forward this process to see if survival and early growth of corals minors can be boosted by the rapid adoption of algae," explained David Subject of -UTS.
