Abstract: Present study was conducted to determine the propagation and biodiversity of corals on artificial reefs at Teluk Kalong and Pasir Akar, Malaysia to check the feasibility of artificial reef to rehabilitate natural reef ecosystems and to provide artificial habitat for marine organisms. Two types of artificial reef deployed in these areas were Dome Reef and EnviroReef which were developed by the Dorken Company. Based on the results obtained, coral distribution was higher at Pasir Akar compared to Teluk Kalong. The Shannon diversity index (H’) and evenness index (EH’) of coral at Teluk Kalong were 0.6425 and 0.1766, respectively while the Shannon diversity index (H’) and Pielou evenness index (EH’) of coral at Pasir Akar were 1.7410 and 0.3247, respectively. Overall, 2 species were found and identified at Teluk Kalong and 10 species were at Pasir Akar with Seriatopora hystrix as the dominant species at both the stations. Coral distribution was higher on Dome Reef compared to EnviroReef. The diversity index (H’) and Pielou evenness index (EH’) of EnviroReef were 0.5359 and 0.1284 respectively while it was 2.2192 and 0.4274, respectively in Dome Reef. A total of 3 and 9 species were found and identified from the EnviroReef and Dome Reef, respectively with Seriatopora hystrix being the dominant in both the reef structures. We conclude that both artificial reefs structures were suitable as habitat for coral propagation.
