This study aimed to evaluate the eff ects of salinity on the growth, survival, feed effi ciency, and shock tolerance of golden trevally juveniles. Juveniles with an initial size of 2.0 cm and 0.18 g/fi sh were randomly stocked in composite tanks (round cylinders) with a volume of 70 L/tank. Four salinity levels were tested: 5‰, 15‰, 25‰, and 33‰. The fi sh were reared at a density of 2 fi sh/L and fed pellet feed at a rate of 5-7% BW/ day, divided into four times per day. Each treatment was replicated three times over a period of 28 days. The results indicated that salinity signifi cantly aff ected the growth parameters, coeffi cient of variation, biomass, feed effi ciency, survival, and temperature shock tolerance of fi sh. In general, fi sh reared at salinity levels of 25 - 33‰ achieved better results than those reared at salinity levels of 5 - 15‰. However, fi sh reared at low salinity levels (5 - 15‰) were found to tolerate freshwater shock better than those reared at high salinity levels (25 - 33‰). Notably, salinity did not aff ect the deformity rate of fi sh. The study suggests that a salinity level of 25 - 33‰ is suitable for rearing golden trevally juveniles.
