The influence of the cool and warm temperatures on early life development and survival of tropical oyster, was studied. D-hinged larvae (day 1 larvae) were reared to three different temperatures (20°C, 27°C, and 34°C) for nine days. Oyster larvae reared in temperature 27°C, acted as control (ambient temperature). The highest survival rate occurred when the larvae were reared in 20°C and 27°C. Larvae reared at 34°C exhibited reduced survival but increase in the growth rate. The growth rate in larvae reared in high temperature (34°C) was significantly higher compared to larvae reared in 20°C and 27°C (<0.05). The results from the present study indicated that tropical oyster larvae, had faster growth rate at the high temperature (34°C). However, the larval survival was decreasing according to days. There is no significant difference in the larval growth and survival in lower temperature (20°C) and control condition (27°C).
研究了凉爽和温暖温度对热带牡蛎早期发育和存活的影响。将D形幼虫（第1天幼虫）在三种不同温度（20°C、27°C和34°C）下饲养九天。在27°C温度下饲养的牡蛎幼虫作为对照（环境温度）。当幼虫在20°C和27°C下饲养时，存活率最高。在34°C下饲养的幼虫存活率降低，但生长速率增加。与在20°C和27°C下饲养的幼虫相比，在高温（34°C）下饲养的幼虫生长速率显著更高（<0.05）。本研究结果表明，热带牡蛎幼虫在高温（34°C）下生长速率更快。然而，幼虫存活率随天数下降。在较低温度（20°C）和对照条件（27°C）下，幼虫的生长和存活没有显著差异。
