The purpose s of this study w ere to determine oceanograph ic and water quality parameters and their suitability for white shrimp Litopenaeus vannamei culture . The measurements were carried out on dry season in Semak Dau n I sland , Karya I sland , and Panggang I sland waters of Thousand Islands, with area s of 315.0 , 12.0 , and 10 2.8 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 Dau n I sland 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 . 8 o C , turbidity of 0 . 1 0 -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 , salinit y of 32 . 2-32 . 3 , dissolved oxygen of 5 . 8-10 . 8 mg/L , am m onia of 0 . 068-0 . 145 mg/L, nitrat e 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.
