Abstract. The Pacific white shrimp (Litopenaeus vannamei) is a euryhaline species that can be reared in aquatic environments with a wide range of salinity, from 0.5 to 40 ppt. The ability of Pacific white shrimps to adapt to extreme saline conditions allows the expansion of shrimp farming in inland aquatic environments, away from the coast. Therefore, this study aimed to analyze the specific growth rate (SGR), survival rate (SR), and feed conversion ratio (FCR) of Pacific white shrimp reared at various salinity levels using a single-step acclimation method. The study employed a completely randomized design with five treatments and three replications, namely T1, T2, T3, T4, and T5 at 5 ppt, 10 ppt, 15 ppt, 20 ppt, and 25 ppt, respectively. Each treatment unit was incorporated with Pacific white shrimp postlarvae (PL) 15 at a density of 2000 PL m-3. Subsequently, the shrimps were fed commercial pellets three times daily through a blind feeding program during the 40 days of rearing. The results showed that different salinities of culture media had an effect on SGR, SR, and FCR of Pacific white shrimp. The most desirable SGR and FCR were observed in the 15 ppt culture media at 12.3% and 1.5, respectively, while the best survival rate was observed in the 20 ppt salinity at 79.3%. Generally, Pacific white shrimp performed best in the culture media with a salinity of 15 ppt. Key Words: euryhaline, growth, L. vannamei, survival rate.
