JBD,
I just joined the forum tonite, and thought I'd chip in as regards to your question on coral transplants.
Over here in West Malaysia, there's a glaring difference in coral diversity and general water quality between our east and west coasts. Our west coast is basically the Straits of Malacca which is a major shipping lane for liners travelling to Singapore enroute to some other Asian country or vice versa. As such, most of the reefs are mostly dead or barren with very little chance of rejuvenation or even survival. Even fish variety has suffered to a large extent since the 70s.
Our east coast however faces the South China Sea, which even though is also used for shipping, is totally exposed and shipping runoff does not concentrate off our coasts at all. This is where we get pristine reefs and fish life.
On the topic of transplants, what a group of friends and I would do in the past was to keep reef tanks at home and propagate corals that could be propagated. Sure, the original source of the mother coral would have been from the sea. But just one of us bought one specimen and propagated it like crazy, for the reef aquaria industry, meaning hobbyists would buy propagated fragments from us rather than entire colonies from the shops.
In the article above, trade in corals is listed as #7 among the 11 or so reason, and we were aware of something like that. As a result, we used to make occasional trips to the West coast, to transplant some of our specimens back into the ex-reefs. On subsequent visits back to the same spot, we'd find surprising recovery and were motivated. But we couldn't proceed much further than that because of insufficient resources (human, time and $$$).
Species propagted - various Acropora, Montipora, Poccillopora, Seriatopora (Staghorns and Elkhorns), leathers and fingers like Sarcophyton, Sinularia, Cladiella, Lobophytum and Lemnalia. Also those so-called soft mushroom corals under the Discosoma genus.
So, it is entirely possible, but it could be a very large and expensive project, but given the chance, I would go back into it without hesitation.
Rgds,
Roger
