Retarded Growth of Cladoceran Zooplankton in the Presence of a Copepod Predator

Abstract

Various instars of four different cladoceran species representing a wide spectrum of body size were grown at high food availability in the presence and in the absence of natural densities of an invertebrate predator, a cyclopoid copepod Acanthocyclops robustus (G. O. Sars). Daily weight increments calculated from individual weights at the end and at the beginning of each 1, 2 or 4 day experiment, showed that individual growth was more or less drastically retarded in the presence of the predator as well as when exposed to water in which the predator had been feeding. The data also showed that the effect of this invertebrate predator was more pronounced in small prey instars and small prey species that were more vulnerable to predation than large prey.
