【 摘 要 】

The study aims to know the biodiversity and community structure of marine tunicate in Samalona waters. The presentstudy is part of biodiversity assessment for marine resources of Sangkarang Archipelago SW Makassar Indonesia. Fieldcampaign was conducted from October to November 2016. Sample collection was done at 3 and 7 m depth by usingLine Intersection Transect (LIT) method combined with a quadrat (plot). Two 50 m transects were placed parallel to ashore line at three stations (sta.) at Samalona waters. A quadrat (plot) (2.5 m x 2.5 m) was placed side by side of the linetransect and all tunicates in the transect was recorded, identified, counted and photographed. Samples were collected byusing SCUBA and under water camera. Environmental parameters including water temperatue, salinity, dissolvedoxygen, clarity, current and wind speed, were measured in situ. Data were analysed using ecological indices includingspecies composition and density, Shanon Wienner species diversity, Evenness, and Morisita Indices. The result indicatesthat there are 18 species of tunicates present at 3 m as well as 7 m depth of Samalona waters.. Result of the ecologicalanalysis shows that species diversity can be categorized as moderate and there were no dominant species. Environmentalparameters indicates that water quality at Samalona waters was in good condition to support tunicates.
