& # 39; underwater crop spreader used for reef regeneration & # 39;

Gold Coast scientists have spent the past year "re-filling" the Great Barrier Reef in the world's first project to regenerate world treasures as a result of the successive years of coral bleaching.

Along with this year's coral mass spawn event at the coral reef, a team of experts used it to harvest coral larvae and harvested it from a mesh fence on the reef.

A specially designed "underwater crop spreader" called LarvalBot was used to sow coral in areas affected by a brutal bleaching event that killed half the coral half last year by experts.

Professor Peter Harrison of Southern Cross University and Professor Matthew Dunbabin of QUT have combined their expertise in raising corals and robots to develop the Vlasoff near Cairns Reef).

Over the last few years, Prof. Harrison has developed a technique for propagating and nurturing 1-mm-long larvae in the Philippines to reproduce the size of coral damaged by dynamite fishing and roughly coral.

Professor Harrison, who discovered coral spawning in the Great Barrier Reef in the 1980s, said coral spread over coral reefs in the summer could give him a chance to succeed because he could have more difficulties with the rehabilitation project.

"These corals have survived the last two bleaching events, and we know they are heat-resistant," Harrison said.

"So they are really what we need to get spawning because we'll give us a larva that gives us the chance to fight over the problems of sea water temperature rise and bleaching"

He said the technology has "tremendous potential" to work in many parts of the UNESCO World Heritage.

"We will closely monitor the progress of the baby coral deposition over the next few months and strive to further refine technology and technology in 2019."

Professor Dunbabin designed LarvalBot to crown crustacean corals and allow them to develop into coral polyps or baby corals by gently releasing the larvae into the damaged coral reef area.

The current ability to move about 100,000 coral larvae per mission has plans to expand to millions of larvae.

An Barrier Reef Foundation executive director at the Great Barrier Reef Foundation said the project was "exciting to see the project go from concept to implementation in a few weeks rather than a few years."

"The recent IPCC report has a very short window on the reef to act for a long-term future, and emphasizes the importance of looking for every opportunity to provide combat opportunities on our reefs.
