Effect of salinity on survival rate of 1-15 days old Grouper larvae, Epinephelus coioides was determined using four levels of seawater salinities included 8, 16, 24 and 32 ppt. The study aims to evaluate the appropriated salinity for nursing the Grouper larvae. Based on the analysis of variance (ANOVA), the results showed non significant difference (P0.05) of survival rate in the samples aged 1, 3, 5 and 7 days groups treated with four levels of salinity. Very low survival rate of these sample groups were obtained from the experiment. After the fish grew up to 9 days, increasing of number of survival fish were found in aquaria containing 16-24 ppt salinities. Survival rate of 9, 11, 13 and 15 days old groups were 45.6-60.6 percent, 39.3-26.8 percent, 64.3-59.3 percent and 73.7-62.5 percent, respectively.
