Abstract
The damage of coral reef ecosystems in Indonesia is increasingly alarming. For this reason, efforts are needed to rehabilitate the coral reef ecosystems. This study aims to evaluate the effect of coral transplantation on the structure of coral fish communities in the waters of Harapan Island, precisely on Rosa Island and Pamegaran Island, Seribu Archipelago National Park. Study of the reef fish community structure was carried out for 8 weeks from February 2018 to April 2019. The observations were conducted by scuba diving to dive directly into the location of the coral transplant. During the study period, a total of 35 species (14 families) were observed. There was an increase in fish abundance per 50 m2 which was significant over time for 8 weeks of observation (alpha 0.05). Significant differences in abundance of reef fish also occurred between the two islands (alpha 0.05), indicating that differences in the depth of the location of coral transplants can also affect the abundance of reef fish. It can be stated that the coral transplantation efforts succeeded in increasing the abundance of individual of reef fish on both coral transplantation islands.
