The regency of Barru is a potential region for Tiger prawn cultured in the South Sulawesi Province. Generally, this aquaculture activity is based on the application of intensively cultivated pattern by using artificial feed as a source of the prawn foremost meal. Some research suggested that an intensive pattern of prawn cultured generates some waste products that are significantly to affect such physical, chemical as well as biological parameters of coastal water condition. That the change in environmental quality of coastal water will affect commercial tiger prawn that is the role of water to support sustainable cultured through its carrying capacity. This research was aimed to analyze physical, chemical and biological parameters of coastal water and to ensure its carrying capacity in maintaining commercially tiger prawn cultured. The results are expected to be some more valuable references for the benefit of the development of tiger prawn aquaculture. The research was conducted in the coastal water from June to December 2007. Observation was made in order to find out physical, chemical, and biological factors throughout the stations (i.e., sea, coastal, pond, estuaria and the outlet of the farm stations). To examine the physical, chemical and biological parameter of spatial characteristic, a Principal Component Analysis (PCA) was used. The used approaches to determine carrying capacity were based on capacity and receivance ability of waters and oxygen content. The results of this research show that the entirely physical and chemical parameters of coastal water of the Barru regency were exceeded that of the requirement thresholds of the total suspended sediment (TSS) and the chemical oxygen demand (COD). A spatial distribution of physical and chemical characteristics was measured high by TSS and COD, as well as the level of water turbidity, all at the outflow of estuaria and the Outlet; meanwhile, the value of NO2, Phosphate, and NH3 substances was recorded high at the pond. A biological parameter was characterized by the existence of phytoplankton through its density and abundance as well. Those of the Class Bacyllariophyceae was dominantly encountered to attain at the top as high as 75.2% in species composition, followed by Cyanophyceae 9.3% at the second, and the rest Chlorophyceae 8.9% and Dyanophyceae and Euglenophyceae 5.9% and 0.7% respectively. Based on the stationed preferences, those in the coastal, the pond, and the Outlet were dominated by Bacyllariophyceae, whereas the estuaria by Cyanophyceae. The Shannon’s index of diversity (H’) of the entirely stations was varied among 1.01 – 2.12 that the lowest one at the estuaria and the highest at the sea. The coastal water has its carrying capacity to support the excess of 506,437 kg organic waste substances based on the necessity of oxygen content suspending in the water column. Therefore, the given pond is feasible to develop to reach as much as 219 Ha intensive ponds, or 481 Ha semi-intensive ponds on the other way.
