Prof. Fredinan Yulianda, Professor of IPB University from the Faculty of Fisheries and Marine Sciences (FPIK) said that coral reef conservation areas have the potential as a source of marine and coastal economy. He said the potential of Indonesia’s coral reefs is very large and is spread over an area of 2.5 million hectares in clear shallow waters. Coral reef areas are generally in small islands and contribute 70 percent of the world’s coral species.
