This study aims to determine the best depth for transplanted coral growth. The type of coral that was transplanted was of the type Montipora foliosa (Pallas, 1766). The study lasted for almost 8 months (October 2014 to May 2015). The method in this study is to conduct field experiments using a completely randomized design (CRD) with different water depths as treatment, namely at a depth of 3 meters, 6 meters, 9 meters, 12 meters, and 15 meters. Each treatment was repeated 3 times to obtain 15 experimental units. The location of the field experiment is on Biawak Island, Indramayu, West Java. The results of the study showed that coral growth with the highest value was at a depth of 6 meters with an average monthly height growth rate of 2.93 mm/month and a monthly width growth rate of 10.26 mm/month, while the lowest coral growth rate was found at a depth of 15 meters with The average growth rate is 0.7 mm/month in height and 2.19 mm/month in width.
