Community Structure of Decapod Inhabit Dead Coral Pocillopora sp. in Pemuteran, Bali
Abstract
Decapod is one of the cryptic fauna associated with coral reefs, which play an important role and accounts for a major part of the biodiversity in the reef ecosystem. However, this biodiversity is largely overlooked and assessment regarding this biodiversity has not been conducted thoroughly due to lack of resources and the difficulties of sample collection. This research used semi-quantitative sampling methods to assess the community structure of decapod species inhabit dead Pocillopora sp. in Pemuteran, Bali. Two dead coral head of Pocillopora sp. were used as pilot study and sampled at the 8-12 m depth. All decapod found were collected and identify into family level. The result showed 214 decapods found consisting 12 families, with Xanthidae as the most abundant family. Community Index which consisting diversity, uniformity, and dominancy, indicated medium diversity, stable uniformity, and low dominancy of decapod community. This result also indicated no dominancy between families of decapod. Meanwhile, Species Density Index showed the value of 84.58 ± 2.04 individual per m3, with mean diversity of 7.05 ± 2.04 individual per m3 for each family.
