Key Words:Daphnia pulex; growth; reproduction; temperature
The growth and reproduction of Daphnia pulex had been studied at the temperature under 35, 30, 25. The result showed that: the growth got slowly with the increasing of the instar number, the life span became shorter and shorter along with the increasing of water temperature.
It was found that at 25, D. pulex showed a higher rate of egg production (=21.22), and produced about 401.6 eggs within a life span of 65.5 days.
According to this experiment, the optimum temperature for D. pulex culture is around 25.
