| Summary: | Coral transplantation has evolved from a reef restoration tool into a proactive strategy for enhancing reef ecosystem value, particularly in marine tourism zones. This study aimed to assess the survival and growth performance of Acropora sp. fragments transplanted onto concrete block substrates in a non-degraded reef area at Wambuliga Beach, Sombu Village, Wakatobi. A total of 58 coral fragments, each measuring 7–10 cm, were transplanted in August 2024 and monitored for eight months. Survival rate and linear growth were evaluated as indicators of transplantation success. The results showed a high survival rate of 89.65% and a final fragment length range of 9–14 cm, with an average growth rate of 0.66 cm/month. These outcomes were supported by suitable fragment size, site conditions, seasonal timing, and the use of durable cement-based artificial substrates with cavity design. The findings confirm that coral transplantation in healthy reef systems can be effective not only for biodiversity enhancement but also for supporting sustainable marine ecotourism and coastal conservation initiatives. |
