Abstract


The present study evaluates the effects of temperature (25 and 30°C) and salinity (25, 35 and 45‰) on juvenile growth and survival. All the experiments were carried out in the laboratory. A total of 270 specimens were used for the experiments. The results showed that more than 83% of the snapper survived at 35 to 45‰ salinity. Significant differences (P<0.05) in growth parameters, such as the specific growth rate (SGR) and weight gain, were observed in fish reared at temperatures of 25 and 30°C and salinities of 35 and 45‰. Increased salinity beyond 45‰ impairs the growth of the Pacific red snapper used in this trial. Salinity tolerance under 35‰ shows that the species has the potential to grow under brackish conditions.
