Abstract:

The growth and survival of Penaeus vannamei postlarvae was measured at temperatures of 20, 25, 30 and 35 C and salinities of 20, 30, 35, 40 and 50 ppt. Groups of 30 animals were used in each combination of conditions, in triplicate. The results clearly show that juveniles of this species have their best survival between temperatures of 20 and 30 C and salinities above 20 ppt. Best growth was obtained between temperatures of 25 and 35 C, with little difference being noted among salinities. Survival and growth coincide best at around 28 to 30 C and 33 to 40 ppt. Calculated overall production was shown to be best in these conditions. The results demonstrate a high coincidence between the experimentally determined optimum conditions for production and the prevailing conditions in the coastal environment from which the animals originated.
