Data on the biomass of commercially important coral reef fishes inside and outside marine protected areas in the Philippines
2019
This article contains the data on fish biomass inside and outside 57 locally managed marine protected areas (MPAs) and within the nationally protected Tubbataha Reef National Marine Park (TRNMP) from 57 coastal municipalities and 20 provinces in the Philippines. It includes the seven major commercially important coral reef fishes, namely, the surgeonfish (family Acanthuridae), parrotfish (subfamily Scarinae, family Labridae), snappers (family Lutjanidae), groupers (subfamily Epinephelinae, family Serranidae), goatfish (family Mullidae), sweetlips (family Haemulidae) and emperor (family Lethrinidae). Fish visual census (FVC) surveys were done by scuba diving along 10 m × 50 m belt transects established on upper reef slope, mostly with depths ranging from 5 to 10 m. Four to twelve transects were surveyed for the locally managed MPAs, half of which were established inside MPAs and the other half outside MPAs. Thirty-three transects were surveyed for the TRNMP. FVC was performed by swimming slowly and stopping every 5 m to record all the fish within a 10 m - wide belt. All FVC surveys were conducted from 2006 to 2014 between 9:00–16:00 hours. Each fish was identified to the species level and total length (TL) was estimated to the nearest centimeter. Fish biomass was estimated using the relationship between length (L) and weight (W) with the equation W = aLᵇ. The data we provide can be used for coral reef fisheries management and for monitoring and evaluation of coral reef fishes in the Philippines particularly for the MPAs included in this dataset. These data support the information presented in the article Muallil et al., 2019.
