Abstract
Fragments of the coral Pocillopora spp. were collected from Carrizales Reef to assess two transplantation techniques for coral reef restoration: (1) coral clusters (CC) technique, in which five to seven coral fragments were joined using plastic straps, and (2) simple aggregation (SA) technique, in which fragments were placed evenly on the seabed. Over 270 days, the transplanted fragments were monitored for various indicators of coral health, including skeletal growth, the proportion of colonizing invertebrates, coral fragmentation, the proportion of algal growth, signs of coral disease, and the degree of fusion of coral fragments. We found 95.5% and 89.0% survival of fragments with the CC and SA techniques, respectively. These results indicate that the CC technique leads to greater stability, merger and integration of fragments, and greater aggregation of the fragments with the substrate at transplantation sites. Both transplantation methods are economical and could easily be applied at a broad scale for coral reef restoration.
