摘要：

By manipulating maternal ration both numbers and lengths of D. magna neonates could be modified. Maternal ration was adjusted by maintaining a constant volume of medium and added food (Chlorella), but varying the number of daphnids per vessel. At low stocking densities, larger numbers of smaller neonates were produced per female than at higher stocking densities, in which fewer, larger neonates were produced per female. The results indicate that careful control of maternal ration is necessary to maintain a predictable supply of uniform neonates for ecotoxicological purposes.
