Cultivating corals

The Caribbean island of Mustique, which lost corals due to climate change and pollution, is about to get them back. Alan Lowe and his Dominica-based Applied Marine Technologies Limited crew have attached 1,200 cultivated pieces of 15 species of coral in Mustique's concrete domes sunk near the ruined reefs. They harvested the corals from the sea. The divers first positioned the half-tonne domes using rubber air bladders and then after removing each bladder, transferred the coral (National Geographic , Vol 200, No 3).
