The largest coral reseeding project started in Great Barrier Reef



Researchers said on Wednesday that they were planning to grow coral larvae from harvested eggs and returned them to reef areas damaged by coral bleaching depending on the climate.

Ün This is the first time that all large-scale larval rearing and settlement processes will be carried out directly on the reefs of the Great Barrier Reef, if said Peter Harrison, one of the project leaders at Southern Cross University.

"Our team will restore hundreds of square meters in the future with the aim of reaching the square kilometers in the future, a scale we have not tried before," a statement said.

The launch of the denk Larval Restoration Project "coincided with the annual coral egg at the beginning of this week, which lasted only 48 to 72 hours.

Along the large-scale corals of the 2,300-kilometer reef, corals have been killed by rising sea temperatures due to climate change, leaving behind skeletal remains in a process known as coral bleaching.

The northern areas of the reef had been intensively bleached in 2016 and 2017, one after the other for two years, and were unable to compensate for the fears.

Harrison and his colleagues were hopeful that resale projects could help reverse the trend, but he warned that efforts alone to save the reef would not be enough.

”Climate action is the only way for coral reefs to survive, dayan he said.

"Our return to restoration aims to save time for survival and development of coral populations, until emissions are limited and our climates are stabilized."

Scientists hope that the coral, which is the bleaching of survival, will have a greater tolerance to the rising temperatures, a reproductive population produced from this year's reproductive population can be better rid of future bleaching events.

Researchers, including experts from James Cook University and University of Technology Sydney (UTS), said an innovation in their reproduction projects was to grow coral larvae with microscopic algae. Two of them live in symbiosis on the reef.

David Suggett of UTS explains, an We are aiming to monitor this process quickly to see whether the survival and early growth of young corals can be increased by the rapid adoption of algae. U
