Kalk, I partly agree with you. The study conducted by IMA along with Bishop Museaum staff and biologists from Fiji found that there was evidence that the removal of coral rock for construction, dry coral for the curio trade, and live rock for the aquarium trade were having detrimental effects on the reefs in the communities involved in these types of live rock harvest in Fiji. By contrast, there was very little harmful effect that could be documented from the collection of live corals for export to the aquarium trade. Further studies are needed, but it seems that live coral harvest, coral farming, and live rock aquaculture (artificial rock placed on reefs), may be more economically beneficial to the villages in Fiji than the removal of natural live rock for construction, and the aquarium trade. Some regulation of the harvest of live rock in Fiji may be necessary to control destructive harvesting practices and protect coral reef communities.
