Marine Biodiversity of Coral Reef Fishes in Pieh Marine Recreational Park After Bleaching and Acanthaster Outbreaks

Highlight ResearchAfter bleaching disturbance and Acanthaster planci outbreaks, herbivore fishes species were dominated in MRP PiehThis explains the marine recreational activities utilization zone Pieh have no impact on reducing fish biomassAfter shows coral reef still endurance event, outbreak after event outbreak. However, composition of corallivorous has decreased but been an increase herbivorous carnivorous populationsAbstractPieh encountered non-anthropogenic phenomena, precisely massive 2016, 2017, predators from outbreaks 2018. This study aimed to understand pattern diversity core area compare it non-MRPS locations that accept same pressure conditions. Coral sampling using a UVC is categorized into three zones: zone, outside area. 8 Families counted based categories level function ecologies economy. Taxonomic distinctiveness estimates calculated mathematically for each sample, including richness taxonomic compared among zonation Pearson’s Coefficient Correlation Matrix was used measure correlation relationship between areas. There are 91 3002 individuals found. The richest family Core Zone Utility Acanthuridae with 20 non-MRP lower abundance communities. dominant Ctenochaetus striatus average abundant per site (21.3 ± 7.62, n = 3). represents 55.98% total biomass MRP-Core Zone, 63.13% MRP-Utility 41.55% Non-MRP Area. showed number populations corallivores carnivore diversity. indices (H’) ENS also differ significantly zonation.
