Abstract
Decapods are marine organism which have burrowing-life characteristic and tend to live in the hard coral, such as Pocillopora sp. Pemuteran district is located in West Bali with high marine biodiversity. In 2016 almost all of the coral reefs in this area have bleached. This research investigates the condition of decapods before and after coral bleaching in Pemuteran. Dead corals, Pocillopora sp., were taken from 8-12 meters depth in 2016. All organisms within those corals were collected and identified until infraorder and family level. Comparison was done with data collected in 2011. This study found 12 families with a total of 5 infraorder which are equal to the previous data. The number of individual has increased from 88 into 214 individual. The mean presence increased from 6.2875 ind/fam to 15.2875 ind/fam. While the density also increased from 23.68 ind/L to 42.09 ind/L. Uniformity and dominance indices for all infraorder is low. These results show that there is an increase of the density of decapods after coral bleaching event, but the diversity of decapods was slightly changed. © Published under licence by IOP Publishing Ltd.
