The dataset describes the actual location of the sampling sites where the benthic and fish surveys were conducted. The data includes the latitude and longitude of survey points, the zonation of the marine protected area, and additional information like the date of the survey and the name of the organization that conducted the survey. |

The dataset describes the condition of fish assemblages in the coral reef ecosystem around the marine protected area. It records the number of individual fish and the estimated body size per fish species assemblage found in square meters. It informs the abundance and biomass of fish species assemblage per square meters. The fish species in the dataset are divided into two groups, target and non-target. The target group consists of fish species that are usually targeted in the fishery sector for having economic value to the area. The non-target group could enrich the diversity of fish species found in an area and provide information about area biodiversity in terms of reef fish species. Sometimes it also records the endangered, threatened, and protected (ETP) fish species or other biota that were observed during the survey.
The survey is usually conducted simultaneously with the benthic survey. Both of these describe the health of the coral reef ecosystem. |

The dataset describes the condition of coral reef and marine substrates (benthic) at a particular depth represented by objects observed every 50 centimeters in 50 meter increments (100 objects) in the coral reef ecosystem around the marine protected area. The result of the analysis will show the percentage covered by substrates that mostly consist of coral reef; it also shows other organisms including algae, sponges, tunicates, and abiotic information like sand, rock, and dead coral. The intention is to observe the health of the coral reef ecosystem by recording the coverage of a sample area.
Gomez and Yap, 1988 describe that 0-24.9% hard coral coverage indicates a bad environment, 25-49.5% moderate, 50-74.5% good and 75-100% best. The data also records coral fractures described in the ‘rubble’ category which usually relates to destructive activity (natural or human) in the coral reef ecosystem. It also records coral bleaching which could correlate with global warming or decreasing environmental quality of marine water. |
