Sea bass is one of species that has wide range salinity tolerance. An experiment was conducted to study the effects of different salinities on survival and growth of sea bass (Lates calcarifer) larvae. Six treatments were compared in this experiment which was 5 ppt, 10 ppt, 15 ppt, 20 ppt, 25 ppt and 30 ppt as control. Each treatment has three replicate and conducted for 15 days. Every experimented tank was provided with one hundred tails of 2 dAH larvae. Desired salinity was decreased 5 ppt from seawater (30 ppt) within 1 hour. Rotifers (Brachionus plicatilis) were fed as the first feeding until 10 dAH and continued by Artemia. Water exchanged, bottom cleaning and larval observation were conducted daily. The water quality parameters were monitored, such as dissolved oxygen (mg/l), pH, and water temperature ( ÌŠC). Every five days, the total length of the larvae was measured for growth performance. The results showed that highest survival and growth was achieved in 20 ppt. Analyses of data revealed that there were significant difference among six treatments (P<0.05) on larvae survival and growth when analyses with one-way ANOVA.
