Transplant nursery-grown coral onto natural substrate
A replicated study in 2015–2019 in two coral reef sites in Lingayen Gulf, Philippines (Ligson et al. 2021, same experimental set-up as Ligson et al. 2020) found that transplanting nursery grown stony coral Acropora verweyi onto natural substrate resulted in 18% of corals surviving for four years, with higher survival for larger transplants at one of two sites. Survival was higher for larger transplanted corals than smaller corals at one site (22% of large vs 15% of small) but survival was similar at the other (15% of large vs 12% of small). Average diameter after four years was 16 cm and did not differ for larger or smaller transplanted corals. In 2015, eleven Acropora verweyi colonies were collected and transplanted to an ex-situ setting. All colonies were placed in a plastic tank for spawning, and egg/sperm bundles were collected and settled on dead coral rubble. Four months after fertilization, 240 pieces of coral rubble with a single coral colony (120 large: 1–2 cm at time of transplant; 120 small: 0.3–0.5 cm at time of transplant) were transplanted to one of two sites, distributed evenly between four bommies (coral outcrops) at each site and inserted into drilled holes with putty. Survival and size were assessed in June 2019, four years after transplant.
