This study estimated the survival rate and growth performance of Snubnose Pompano Trachinotus blochii larvae at different levels of salinity: 25, 33, 39, and 42‰. The experiments were conducted in triplicate, with 1,000 larvae per tank, and the control group was maintained at a salinity level of 42‰ at 28.3–31.0°C. At 18 h posthatch, the larvae were transferred directly to the four different salinities and their survival and growth rates were monitored. Our results indicated that the appropriate salinity for the survival of Snubnose Pompano larvae is 33–39‰, and 100% mortality was observed within 4 d posthatch at a salinity level of 42‰. Growth performance was not significantly different between the groups, except in the control group. After 21 d, strong cannibalism in the 25‰ groups was more evident than it was in the other groups. Overall, the results indicate that the larviculture of Snubnose Pompano is feasible at salinities of 33–39‰.
