Effects of temperature and Ca2+ on the larval development of the decapoda crustacean:Eriocheir sinensis
摘要
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.
