Abstract
This study was undertaken to evaluate the influence of temperature (18, 23, 28°C) on survival rate and final weight of Penaeus paulensis postlarvae (PL 10) during a 25-day intensive (1800 PL/m 2) nursery trial in indoor tanks. A survey was also conducted in earthen nursery ponds to evaluate the influence of water temperature on the growth rate of P. paulensis in commercial farms. The survival rate achieved at 18°C was significantly ( P<0.05) lower than that observed at the other two temperatures. Final weight increasing as the temperature increased with the mean weight at 28°C being significantly ( P<0.05) higher than at the other two temperatures. The results showed that low water temperature affects the survival rate of P. paulensis when cultivated at 18°C during the nursery period. Growth rate was positively correlated with water temperature within the range tested. Data from a field survey suggested this positive correlation could be applied to postlarvae cultured in earthen ponds.
