Assessment of Temperature Effects on Early Larval Development Survival of Hatchery-reared Tropical Oyster, Crassostrea iredalei

The influence of the cool and warm temperatures on early life development and survival of tropical oyster, Crassostrea iredalei 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, acte...

Description
Summary:The influence of the cool and warm temperatures on early life development and survival of tropical oyster, Crassostrea iredalei 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 ( p
