The best estimate I've seen is 1-10% aquacultured for both fish and coral. I can't remember the name of the report right now, but it was from 2003. However, those numbers are based on import/export numbers and do not include fragging by local hobbyists. There is currently another large report in peer review right now that says the coral numbers are up around 15% now with the large mariculture operations producing now (Walt Smith?).
I would GUESS that fragging adds another 5-10% of aquacultured onto the corals, but there is no good way to track fragging.
Regardless of fragging, aquaculture is rising, but is still a very low percentage of the animals in our tanks. A great many of the fish and mobile invertebrates in our tanks are still 100% wild caught as we know nothing, or next to nothing, about their reproduction.
