| 摘 要： | With increasing demand in China for the mitten crab larvae, understanding its survival mechanism gets more important. This research focused on the effects of temperature and Ca^2 on the larval growth and development. Eriocheir sinensis larvae were reared in laboratory under 21 different combinations of temperature (15, 20, 25℃) and Ca^2 content (120, 130, 140, 150, 160, 170, 180mg/l) and constant salinity (20) and pH (8), The results suggested that the survival rate increases with temperature and Ca^2 content. These combinations of temperature and Ca2 content maximized survival rate inour study and it may be the optimum water environmental conditions for culturing the larvae. To predict surviving larvae number under different water environmental conditions, 21 dynamic mathematical models were developed. This for the first time observation of the zoeal Ⅵ larvae of the Changjiang River E.sinensis population showed that they occurred under stressed water environmental conditions: temperature of 15℃ and Ca^2 content of 120,130mg/l.

| Abstract: | With increasing demand in China for the mitten crab larvae, understanding its survival mechanism gets more important. This
research focused on the effects of temperature and Ca2+ on the larval growth and development.Eriocheir sinensis larvae were reared in laboratory under, 21 different combinations of temperature (15, 20, 25°C) and Ca2+ content (120, 130, 140, 150, 160, 170, 180 mg/l) and constant salinity (20) and pH (8). The results suggested that the survival
rate increases with temperature and Ca2+ content. These combinations of temperature and Ca2+ content maximized survival rate in our study and it may be the optimum water environmental conditions for culturing, the
larvae. To predict surviving larvae number under different water environmental conditions, 21 dynamic mathematical models
were developed. This for the first time observation of the zoeal VI larvae of the Changjiang RiverE. sinesis population showed that they occurred under stressed water environmental conditions: temperature of 15°C and Ca2+ content of 120, 130 mg/l.
