I have not conducted any coral transplantation work in the field but we
handle a lot of coral fragments in culture and the techniques could be
applied to field situations. Others can inform you how they transplant
corals on the reef, but on our "farm" we snip off fragments roughly 3-5cm
in length (mostly Acropora spp.). These are immediately glued onto
small, cubical nylon plugs ("faucet adaptors") using Z-Spar splash zone
compound (A-788). The plugs are then set into the slots in a plastic
eggcrate tray in an outdoor aquarium. We can grow dozens of fragments in
a very small space this way. The fragments are then used for research,
or given to other public aquariums, or used in our own exhibits.
I see no reason why this method could not be expanded to grow fragments
to transplant on the reef. The plugs could either be snipped off or used
as anchors to hold the coral fragments in small holes on the reef. Of
course, the plugs would have to be secured with underwater epoxy to
ensure that they stay in place. This would require an underwater drill,
and probably regular trips to the surface to get additional epoxy -- it
starts to become unworkable in about 10 minutes.
My gut feeling is that transplanting corals on the reef is more trouble
than it's worth, given all the logistics involved, but there probably are
reef areas which might be unsuitable for the settlement of coral planulae
but otherwise have conditions suitable for coral growth. Such areas
might be candidates for transplanting fragments.
