Abstract

The purposes of this study were to determine oceanographic and water quality parameters and their suitability for white shrimp Litopenaeus vannamei culture. The measurements were carried out on dry season in Semak Daun Island, Karya Island, and Panggang Island waters of Thousand Islands, with areas of 315.0, 12.0, and 102.8 ha, water depth average of 4.6 m (0.5-28.1 m), 14.6 m (0.5-26.7 m), and 5.3 m (0.8-13.6 m), mean current water velocity of  12.9, 12.7, and 13.5 cm/second, respectively.  In the study areas, we found a diurnal tidal pattern with high wave in January and July-August.  Based on temperature, salinity, and water density in Semak Daun Island waters, there seemingly occurred a turn over indicating a good water circulation, while in Panggang Island and Karya Island waters tended to have a stratification. Generaly, water qualities in the study areas were in the op-timum range for white shrimp culture, i.e., temperature of 29.6-30.8oC, turbidity of 0.10-1.05 NTU, transparency of 5.8-9.7 m, total suspended solid of <8 mg/L, total dissolved solid of 20-164 mg/L, pH of 6.89-7.22, salinity of 32.2-32.3, dissolved oxygen of 5.8-10.8 mg/L, ammonia of 0.068-0.145 mg/L, nitrate 1.247-2.589 mg/L, and phosphate  of 1.021-2.352 mg/L. Moreover, in Semak Daun Island wa-ters, we found the highest suitability for white shrimp culture due to its better water circulation.

Keywords: mariculture, coral reef waters, strait, water current, turnover, stratification.
