I would prefer to buy corals from a farm than have them taken from the ocean.
Just a personal preference.
Fish as well. Even if there were studies that say there are sustainable populations in the ocean. Unless they were outgrowing their environment and it couldn’t sustain the population. Then harvest some to help the corals thrive. Most of my corals were given to me from others fragging their corals, looking for someone to take them.
I know it would be much more expensive to buy corals. We have some great facilities in Florida that do this already.
Again, the problem with aquaculture is that, from a net perspective, that requires a lot of energy and water. While corals are essentially free. Within reason, harvesting of corals is very sustainable.
A very small minority of the species and colors of corals appear in the hobby, because they are not colorful. Porites lobata, allegedly the most common coral in the world, is not available for sale from any coral vendor. Even Pocillopora damicornis, the types availalbe for sale are colorful, whereas the hundreds of P. damicornis I've seen in the wild are not remotely colorful.
Also, I believe that, while frags are generally aquacultured, many colonies come from the wild or from mariculture areas.(I believe availability is also seasonal; I've noticed the number and type of corals and clams available now is expontentially better than a few months ago, I'd imagine for for natural and economic reasons). Again, the individual colonies chosen are selective: the most colorful. (which I believe often are cut up into frags at the retail level when available).
This is completely sustainable, as long as there are catch/harvesting limits. The number of uncolorful individuals of a given species are many times the colorful ones. I believe very little direct retail harvesting of wild corals takes place. Even at the wholesale level, catch (harvest?) limits for wild corals, or reliance on maricultured (grown in the sea) can mitigate much of the danger to wild populations.
Fish is a whole different bag. I again think that some species like clowns can be easily aquacultured, but others have a life cycle that's very difficult to commercially aquaculture (assuming you knew how). Again, I think for wild species, international catch limits are the way to go, and careful monitoring at the wholesale level. (to say nothing of ensuring the amount of die off is minimized......)
I think most people wouldn’t mind paying a bit more for livestock that is of better quality when it makes it way to our tanks.
I don't know about "most people". But I'm definitely in this category.
