Abstract

Coral reefs are an important ecological resource which must be protected and conserved. Previous studies on the coral reefs of the Talang-Talang Islands (TTI) have found the percentage coral cover to be low with the reefs undernourished and underdeveloped. The objective of this study is to determine the present hard coral percentage cover of the Talang-Talang Islands. It also seeks to determine the composition of coral genus as well as the Genus Diversity of the TTI. This study also aims to find the correlation between the coral diversity of the TTI with various ecological factors such as fish and invertebrate diversity and the rate of sedimentation. The coral cover survey was carried out using the Point Intercept Transect Method (PIT) while the Coral Genus Diversity survey was concluded using a modified PIT. The results were significant, with 71% average live coral cover. The results were compared with previous studies and were found to be significantly different. A total of 27 coral Genera were sampled from 15 Families. Shannon-Weiner Diversity Index= 2.90; Simpson Diversity Index= 0.07, Berger-parker Dominance Index= 0.17 and Pielou’s Evenness Index= 0.88. Statistically significant correlation between coral diversity and fish diversity were found with r=0.9622. Correlation between occurrences of massive growth forms was suspected but could not be correlated due to small sample size. The coral reefs of the Talang-Talang islands are diverse but poorly understood. More studies need to be conducted to better understand this important ecological resource.
