Abstract:

The purpose of this study was to evaluate the effects of food concentration, animal interaction and water volume on survival, growth and reproduction of Daphnia magna under flow-through conditions. A response surface design was used to determine the interactive, as well as the individual, effects of the three factors. Results indicated that there was no important interactive effects of the three factors on survival, growth or reproduction of D. magna. Individual effects of the factors on reproduction were observed. Food concentration produced a linear trend with increasing food resulting in an increase in offspring production. The number of daphnids per container produced a quadratic trend with the maximum offspring production occurring in vessels containing approximately 14 daphnids. Water volume produced a slight linear trend with increasing water volume resulting in an increase in offspring production.
