Although I really love how no one cares about the state of the reef where all of these corals originally came from. They only care that the corals got more expensive. We need to get sustainable and we need to do it now before our hobby is gone for good.
Worldwide, coral reefs are definitely in worse shape than they were say 100 years ago, due partially to climate change (I've seen this with my own eyes on a particular reef) but also more generally due to massive human development in that time without regard for the health of the on-land or oceanic environment (e.g. nutrient runoff and sedimentation) and sometimes destructive food-fishing practices. Many areas - particulary where there's dense or high amounts of human life (Indonesia, Philippines, some parts of Fiji), and where overfishing for local and foreign dinner tables, the export of live fish for aquariums, and to be slaughtered and cooked restaurants in Asia (yes - the export of
live fish to restaurants supposedly exceeds the value of live fish for aquaria by several multiples) - have poor coral coverage and are overfished.
However, there are still plenty of corals in the wild. Some small reefs which alone could cover the entire worldwide frag demand.

In Marau Sound there is a vast array of Acropora, as many as you could imagine and so many you could look in every direction and see solid corals for as far as you can see in the clear waters. There are enough corals in this one location to supply the worldwide reef hobby for 20 or more years! There was no signs of bleaching or other problems. On these secluded islands of Marau Sound live our coral farmers, the ladies of Marau Sound.
The laborious work by the skilled local divers and their care and attention to detail was inspiring and appreciated as they constantly thought about quality and getting their prized collections to us alive and healthy.
Further, colorful corals are only a small percentage of the corals available. The vast majority of the corals are not of the right species, or are not colorful enough, to warrant warrant collection. The most common corals in the world, Porites lobata and Pocillopora eyoudxi, are completely absent in the aquarium hobby. (and are not colorful - and no I'm not talking about Pocillopora damicornis - certain color variants are common in the hobby, though very rare in the wild since most of them have a sort of whitish or brownish color.

It takes far money time, money and effort to supply an aquaculture frag than a wild caught and chopped frag. Unless customers are willing to pay more for an aquaculture frag we will continue to harvest from the ocean until nothing is left, have any of you watched chasing corals on Netflix? It might already be to late, our reefs are dying and our hobby is on the line. If you don’t support fragging and aquaculture then you are just as bad as the people pulling everything out of the oceans unsustainably.
I'm sorry, this makes no sense. This may have been true years ago when there were lots of corals that could be harvested near major airports in shallow waters. But when you start adding in diving for corals (like our collectors in the Solomons do in the quote above), in places quite far from national distribution centers, the cost goes way up.
There are several ways of getting corals to someone in the US:
- Collecting them in the wild wherever you can, getting them to a local country distributor facility near a major airport, flying them to a US distributor generally in LA, getting them to the LFS and then to the customer. This of course has the greatest chance of casualties.
- Cultivating species that are known to sell well in the ocean near the local country's major airport, and then getting them to LA, etc. (as an aside, coral farms for local restoration can do this on the side. Apparently a lot of the Australian market is supplied by such farms in Australia)
- Cultivating species that are known to sell well in a large facility on the shore, which pumps NSW into their greenhoused tanks daily to minimize light and water change costs. (I believe there are several facilities like this in Australia and a few in the U.S., most notably ORA). This and option #2 are far and away the most efficient, distribution-wise. However, they do need to be replenished with seed stock every so often.(some facilities are inland enough they must use ASW, or must use artificial lights for their zoas/LPS and greenhouses for their SPS and clams. Pacific East Aquaculture is one such place)
- Cultivating species known to sell well using all artificial lighting and saltwater. This is the least efficient, but potentially the closest to the customer, and easiest to scale. AquaSD in San Diego I believe is a large example. Your average LFS is another example. A number of hobby-business side jobs are also generally smaller examples of this. (though some hobbyist frag tanks are bigger than some LFS' I've been too!!!)
I'll go out on a limb and say it's far more practical to commercially cultivate and sell zoas and softies in captivity than to collect and export wild-caught zoas/softies to the end user (again, especially since not every variety is colorful - thus the existence of so-called "trash zoas").
I'd say the same thing about some of the more common, commercially viable, cheap hard corals - the commonly found variants of Pocillopora damicornis, Favites pentagona (war coral being very one common variant), Favias, Monti cap, etc. These grow fast, well, and easily in captivity without too much fuss.
It's when you get to things like Acroporas that you start to find areas where wild collection is more viable, since they're often finickier.
But I can think of at least two scenarios where this is not the case: First is high priced frags from relatively small vendors. If we talking about a premium acro, say a Walt Disney, it's far easier to get one in a marketable color, grow it and frag it occasionally for $100, while it's practically impossible to go and find something with the same colors under actinic in the wild.
Second, some acros - e.g. Red Planet A. anthocercis or hyacinthus- I'd bet are still easy and cheaper to cultivate in captivity versus collecting and exporting marketable Acros of the same species from the Solomon islands, Sulawesi, or even maybe Cebu. I'd imagine ORA has several separate troughs in a greenhouse with several large Red Planet colonies they they constantly frag from.
Where wild collection has its place is where you need to keep up breeder stock, where you want nice but not great colored coral colonies, or you're looking for something nice to frag among dozens of collected corals. I don't think the later is a very good model, personally, but I know people still do it.
