The coastal area of Labakkang District has a wide brackish water pond, but its productivity is relatively low. A research to determine land suitability as one of the brackish water pond productivity raising project is needed. Considerable factors in determining land suitability for shrimp aquaculture covers topography and hydrology, soil conditions, water quality and climate. Quality of water is observed during rainy and dry season. Spatial analysis using Geographic Information System is applied in the determination of land suitability for shrimp aquaculture. Results of the analysis reveal that within an area of 4,986 ha of brackish water pond in Labakkang District, there are 1,059 ha classified as highly suitable (class S1), 2,676 ha of pond is moderately suitable (class S2), 1,151 ha of pond is marginally suitable (class S3) and 102.7 ha is not suitable (class N) during rainy season, while during dry season there are 10.26 ha classified as S1, 3,591 ha classified as S2, 225,97 ha classified as S3 and 360.9 ha classified as class N. Delimitation factors during rainy season is flood, while salinity is the main limiting factor during dry season. Generally, other limiting factors are country mile of the water sources, low level of pH soil and roughness of soil texture in certain area.
