This study aimed to determine the appropriate salinity range for early juvenile of spotted scat fish (Scatophagus argus). The experiment included 7 treatments of salinity as 5, 10, 15, 20, 25, 30, and 35‰. The experiment was randomly set up in 100L tanks in triplicate. The fish was stocked at 1 ind./L of stocking density with the initial weight, body length and body high were 0.022 ± 0.002 g, 7.83 ± 1.84 mm, and 4.26 ± 0.35 mm, respectively. After 20 days of rearing, no significant difference in fish growth performance (DWG and SGRW; DDG and SGRD; DLG and SGRL) was observed among treatments (p > 0.05). The fish survival ranged from 56.7 to 98.9%, and was statistically different among treatments (p<0.05). In which, the highest survival rates were recorded at 5 and 10‰ of salinity (98.9 and 90.6%, respectively) (p<0.05).
