Use settlement tiles made from unnatural materials to encourage natural coral settlement
A replicated study in 2019 at a reef at Sir Abu Nu’Ayr Island off the United Arab Emirates (Bento et al. 2021) found that terracotta settlement tiles were naturally settled by stony corals (including Acropora spp. and Porites spp.). An average of three corals settled/tile, and all but two recruits settled on the grooved underside of the tiles. Acropora spp. made up 30% of settled corals, and Porites spp. made up 10%. In April 2019, thirty-one terracotta tiles (10 × 10 × 1 cm) were attached to the reef substrate (5 m deep, 2 m apart) using a screw and epoxy, with the grooved surface facing down. In September 2019, tiles were collected, and the number of recruits were counted, and species were identified.
