Marine aquarium trade (live corals) Lime production In Solomon Islands, chewing betelnut is a long-standing and common tradition. Calcium car- bonate is the active ingredient of lime and forms the basis of the skeletal structure of staghorn corals (Acropora spp.), which are harvested on the reef. All Solomon Islanders, especial- ly those who chew betelnut, are familiar with lime. Daka or leaf, lime and betelnut are all essen- tial ingredients in betelnut chewing because without one of these, the desired taste cannot be achieved. Betelnut chewing is part of Solomon Islands tradi- tional culture and enhances socialization among people. Staghorn corals used for the production of lime.

This area had a very diverse population of hard coral species. Although freshwa- ter runoff has caused mortality in the surface layers, healthy coral colonies were observed in the deeper parts of the mangrove. Collectors use a dugout canoe as the collection vessel and take turns diving. The group harvests corals with a screw driver or chisel. Coral fragments are then placed in a plastic basket on top of a layer of mangrove leaves. On the day of the visit, the SPC/ MFMR team observed a harvest of Lobopyllia spp., Euphyllia spp., Ricordia spp., and Merulina spp. Back at the village, the corals are placed underwater in surround- ing areas, to ease the acclimati- zation of the freshly harvested Wild caught coral in the Nggela. 1 Lal P. and Kinch J. 2005.
