lkan dingkis merupakan ikan yang hidup berasosiasi dengan terumbu karang dan padang lamun. Bagi masyarakat Pulau Abang, ikan dingkis merupakan ikan target dan jadi incaran terutama pada saat perayan Imlek karena harganya cukup tinggi khususnya yang mengandung telur.

Data was collected in May and June 2009. Transect square method was used to describe the condition of the coral reefs and seagrass and analysis using Image J. The abundance of fish was determined with Under Water Visual Census. Furthermore, food habits was analyzed using the Preponderance Index. Clustering analysis was used by using the Bray Curtis Index and to see their relevance was done using Pearson correlation (r). The results obtained was: (I) The condition of coral cover was poor to moderate category between 21.83% - 64.49%, while for the algae varied between 2,77% - 57.62%, (2) The condition of seagrass cover varied between 1620"10 - 67.90%.
