This study was conducted at Gayana Eco Resort (06°00'46.84"N, 116°02'59.07"E) located in the Malohom Bay of Gaya Island. Snorkeling and diving surveys were carried out to determine the major marine ecosystems in the study area. Coral reefs and seaweed ecosystems were determined to be the major marine ecosystems. An assessment on the status of coral reefs of 3 sites were selected for Reefcheck survey which comprised of the fish belt transect, invertebrate belt transect, point sampling and coral impacts. The seagrass and seaweed beds percentage coverage surveys were done according to the Line Transect and Quadrat method. There were 6 stations selected for the survey. The data collected from all the surveys were mapped to show the distributions of coral reefs, seagrass and seaweed bed of the study area. The total indicator fishes recorded in the study area were 41 individuals and 53 individuals in the shallow and mid reef respectively. While, there were 281 individuals of invertebrates recorded at the shallow reef and 9 individuals from the mid reef. In addition, the percentage of hard coral cover in the study site was categoried under poor condition which was less than 25%. Moreover, the study area was recorded with high degree of coral impacts which due to the general trashes and others factors. Besides that, there was fishing activities observed during the survey. Halodule sp. and Enhalus sp. were the two species of seagrass determined within the study sites. But only Halodule sp. was found in the quadrate of the survey with the percentage cover of 8.65%. On the other hand, Sargassum sp., Turbinaria sp., Padina sp. and Halimeda sp. were the four species of seaweeds that found in the area. The total percentage of seaweed coverage in the study site was 21.73%. Lastly, the collected data was put into map to show the spatial extent of the coral reefs, seagrass and seaweed beds of the study area.
