  1. Repurpose obsolete offshore structures to act as structures for restoring coral reefs

    A replicated study in 1996–2003 at an aquaculture site at Miako Island, Okinawa, Japan (Omori et al. 2006) reported that coral cover was higher inside empty aquaculture boxes compared to the surrounding reef. After seven years, coral cover inside five boxes originally designed to be used for rearing top-shell snails Trochus niloticus was 90% compared to 20% on the surrounding reef (data not statistically tested). By 2003, twenty-six species had colonized the base of the boxes, dominated by stony coral Acropora spp. that had grown to 40-65 cm in diameter. In 1996, five concrete aquaculture boxes (2.1x2.1x0.6 m) in shallow water (depth not specified) were left empty to enable coral to grow on the base. The box bases were made from plastic lattice reinforced with quartz sand-coated fibreglass to which the corals could attach. Monitoring frequency and other methods are not reported.
