ABSTRACT The purpose of this study was to develop a successful culturing system for Ceriodaphnia dubia/affinis. Seventeen different algal foods were offered to C. dubia/affinis, and their effect on fertility and longevity observed. The best single algal food of these seventeen, in terms of neonate production, was Ankistrodesmus convolutus cultured in an inorganic defined medium supplemented with crystalline B12, biotin, and thiamine. This green alga is cultured and fed to C. dubia/affinis axenically, and the zooplankton are maintained in sterile culture although the animals themselves are not bacteria-free. Demographic data obtained from individual animals reared at 20°C and at 24°C showed that reproductive frequency is greater at 24°C than at 20°C, but the mean brood size is somewhat larger at the lower temperature. Longevity studies showed that animals survive longer periods at the lower temperature. One female lived 125 days and during that time produced 29 broods. Starvation data confirmed the success of the experimental diet, in that neonates carried sufficient lipids from their mothers, survived and matured to reproduce, in the absence of food, for approximately eight days. A successful batch culturing system is described.
