In a time where the coral reefs are dying at an unprecedented rate Dr. Dave Vaughan, former Executive Director at the Mote Marine Laboratory in Florida, accidentally found a way to increase the growth rates of corals by a factor of 25-40 . The technique called “microfragmenting” works by essentially cutting living corals into 1-5 smaller polyps using a specialized saw. This stimulates rapid healing and growth. The corals are then placed in a water tank where they will grow to full size over 4-12 months, after which the process can be repeated or divers can replant them at the reefs.
Dr. Dave Vaughan currently employs his technique with aim at restoring the Florida Reef Tract, which is the earth’s third largest coral reef and a vital ecosystem for underwater life. Furthermore, Dr. Dave Vaughan trains others in the technique, enabling them to set-up nurseries of their own from where they can help restore their local coral reefs.

Fucking corals is no longer the fastest way to grow their population.

So essentially he's growing clones. Ok, so we can put them everywhere. Soon enough we'll be reading headlines about lacking genetic diversity allowing the unhindered spread of some diseases, thus again bleaching of corals, and we'll be back to square 1.
What I'm saying, this may be one helpful measure, but won't be the be-all-end-all solution.

Genetic diversity is a massive problem.

How is the DNA diversity done with corals? And can it be done "hand made"?
I can see a way to use his method by having lots of corals starting point, and from there in each "vat" have the corals grow different DNA "manually"

So... if I take a city, break it up into five pieces and put the people in five different places, I'm cloning humans?

If you take a worm, cut it in 2 and let both parts regrow, they'll have the same genome. Same with the polyp.
We're talking multiplying individuals, not diverse populations.

No, I didn't get that from TFA. Following a link from TFA, I find "We take fragments of these corals, chop them into tiny microfragments, and allow genetically identical microfragments to fuse..." - that doesn't yet sound like genetic diversity to me.
Further, they write "Plant approximately 70,000 coral fragments of diverse, endemic genetic varieties" - ok, there we're getting somewhere, in the future.
They also write about targeted breeding for genetic variety... so it's not only about these clones. Which was my point.
EOT for me.

They can claim they were building on this research and trying to clone Jamal Kashoggi. For science.
