Özet

Four temperatures (22 degrees C, 26 degrees C, 30 degrees C and 34 degrees C), and the combined effects of three salinity (25, 30 and 35 ppt) and three temperature (26 degrees C, 30 degrees C and 34 degrees C) levels from protozoea 1 (PZ1) to postlarvae 1 (PL1) stages of Penaeus semisulcatus were studied in two separate experiments. In the first experiment, the PZ1 larvae at the lowest temperature of 22 degrees C showed the highest survival (69%) to PL1 compared to 61% at 26 degrees C, 44% at 30 degrees C and 12% at 34 degrees C. However, 22 degrees C slowed the growth and delayed the larval development by about 2-4 days. Growth rate at 30 degrees C (0.44-0.48 mm day(-1)) was double of that (0.22-0.25 mm day(-1)) at 22 degrees C. The results showed that P. semisulcatus is tolerant to low, rather than to high temperatures during the larval development. Hence, a water temperature; level of about 30 degrees C is optimal for the larval culture of this species.
