外文摘要：Pseudodiaptomus dubia is a calanoid copepod that is distributed widely in the estuarine-coastal waters of Asia and is a dominant copepod in the shrimp grow-out ponds in southern China. A laboratory culture experiment was conducted to evaluate the influences of water temperature on larval development, survival, and reproduction. Results indicate that within a temperature range 15 to 35 degrees C, larval development increases as the temperature increases. The water temperature for optimal larval survival rate ranges 20 to 35 degrees C. Longevity and egg hatching time decrease as the temperature increases 20 to 35 degrees C. Total fecundity and reproduction frequency increase as the water temperature increases, with the maximum at 30 degrees C. Fecundity and reproduction frequency decrease when the temperature exceeds 30 degrees C. Intrinsic growth rate (r(m)) ranges 0.168 to 0.195 at 25 to 30 degrees C; net reproduction rate (R-0) and finite growth rate (lambda) are 163 to 264 and 1.183 to 1.215, respectively, when the temperature is greater than 20 and 35 degrees C; population doubling time (t) varies 3.556 to 4.128 days at temperatures less than 20 and 35 degrees C. Population generation time (T) is negatively correlated with temperature, with the optimal population growth rate at 25 to 30 degrees C.
