The present study evaluates the effects of temperature (24, 29 and 34ºC) and salinity (15, 25, 35 and 45 ups) on the growth and survival of L. guttatus juvenile. All experiments were performed in a recirculating system with cylindrical tanks 80 L and three replicates per treatment. A total of 360 specimens were used for the experiments. The results showed that in interaction salinity-temperature, statistically significant differences were found (P<0.05). It was presented the highest specific growth rate at 34°C and 15 ups treatment. The higher growth was obtained in the treatment of 34°C and 25 ups. The greater survival occurred in the treatments of 24°C and salinities 15 to 35 ups. The tolerance to low salinities for this species, shows that L. guttatus has a high potential to grow in the lagoon-estuarine systems and represents an alternative to diversify the marine and coastal aquaculture.
