The growth and survival of Penaeus uannamei postlarvae was measured at temperatures of 20,
25, 30 and 35°C and salinities of 20, 30, 35, 40 and 50%0. 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%0. 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 4O%“c0. 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. 0 1997
