    Identifying the key threats that influence coral reef ecosystems, one needs accurate information about coral health status to provide information for enhancing coral reef management. In this study, the health status of the coral reefs in the Pulau Perhentian Marine Park (PPMP) is characterized by using two ecological components, benthic (BI) and fish (FI) indexes, which were combined to form a two-dimensional Coral Health Index (2D-CHI). The BI was determined based on data collected using the Coral Video Transect (CVT) method, while the BI using the data collected using Underwater Visual Census (UVC).

    (Universiti Pertanian Malaysia Press, 2019) Zuraini Zainol; Azizi Ali; Mohd Safuan Che Din; Mohd Fadzil Akhir; Zainudin Bachok; Ahmad Ali
    Degradation of coastal water quality is one of the major concern in the Malacca Strait since this area is one of the most important fishing ground in Malaysia. Despite being great in the fishery industry, Malacca and Negeri Sembilan somehow recorded the lowest marine fishes landing, which raises a question about dynamics of this area. It is therefore, a preliminary study of the physical properties and nutrient concentrations carried out from 27 March to 4 April 2016 at the coastal water off the southern west coast of Peninsular Malaysia, specifically at Pulau Besar, Malacca and Tanjung Tuan, Negeri Sembilan. Data for temperature, salinity, and dissolved oxygen (DO) was acquired by using Conductivity, Temperature, and Depth (CTD) probe. Meanwhile, nutrient concentrations determination in this study was done by using a Westco Smartchem 200 Discrete Analyser, according to the procedure adopted from United States Environmental Protection Agency (USEPA).
