Coral reefs along the Malacca Straits (MS) are poorly developed mainly due to turbidity and sedimentation. This study describes the health status and community structure of the corals in Cape Rachado, West Coast of Peninsular Malaysia (WCPM), utilizing the Coral Video Transect (CVT) technique. All the survey transects were categorized as ‘fair’ coral conditions (27.39 ± 5.41%–48.56 ± 18.96%) with the reef floor mainly covered by corals and sediment. Twelve families of coral comprised of 25 distinct genera were identified. Coral communities were differentiated into four clusters with each being predominated by Galaxea, Diploastrea, Fungia and Pectinia respectively. Among all, Pectinia is the most spectacular genera and dominated the survey area. Along the MS, Favia, Favites and Porites are commonly found while Porites and Pectinia dominated the reefs. Low coral cover and diversity was recorded in MS as compared to the reefs in the South China Sea (SCS). The most prominent results include changes in the dominant coral from Porites to Pectinia while some species such as Acropora were absent from the study area. Based on the presented data, the reef in the study area was predominantly occupied by sediment and the coral communities were formed by a species with a high tolerance to turbidity and sedimentation.

Tropical coral reef fish assemblages in the South China Sea (SCS) have not been well-studied; thus, this research investigated the species richness of coral reef fishes at Pulau Bidong and the surrounding islands of Terengganu, Malaysia. Fish surveys were conducted using the Stereo-Diver Operated Video System (Stereo-DOVs) technique from July to October 2019 at 14 sites with different underwater reef structural features. A total of 8259 individuals and 52 reef fish species belonging to 14 families with a density of 23.597 ind. m− 3 were identified and counted from the surveys. Among the families, Scaridae (parrotfish— herbivore), Labridae (wrasse—invertivore), Serranidae (grouper—carnivore), Lutjanidae (snapper—carnivore), and Chaetodontidae (butterflyfish—corallivore) were commonly recognized as indicator fishes for reef health. Based on trophic groups, the proportion of herbivores was significantly highest (51%), followed by carnivores (26%), invertivores (21%) and corallivores (2%). Among the indicator species, Scarus psittacus (Scaridae—parrotfish; Common Parrotfish, 0.829 ind. m− 3) was predominant, followed by Lutjanus lutjanus (Lutjanidae—snapper; Bigeye Snapper, 0.463 ind. m− 3) and Thalassoma lunare (Labridae—wrasse; Moon Wrasse, 0.229 ind. m− 3). The fish communities found at each station were 80% similar between locations. The density at each station ranged from 0.280 to 4.834 ind. m− 3, the diversity index (H′) recorded was between 2.186 and 3.492 and evenness (J′) ranged from 0.610 to 0.862. The high abundance and diversity and significant proportion of indicator fishes might indicate that the coral reef ecosystems at Pulau Bidong and surrounding islands are in good condition. This study offers significant ecological data on fish assemblages of tropical coral reef ecosystems, specifically in the SCS region on the east coast of Peninsular Malaysia.
