Abstract This paper examines seasonal changes in the density and taxonomic composition of the zooplankton of a small tropical impoundment, in relation to factors of water temperature, food supply and reservoir flushing. The response of the zooplankton to management techniques designed to regulate the density of cyanobacteria in the dam are also considered. Cyclopoid copepods were the dominant zooplankters, although Cladocera became much more significant following the introduction of measures to control cyanobacteria. Planktonic Rotifera were a diverse but generally unimportant fraction of the total biomass, except following seasonal or management induced environmental perturbations, when the Rotifera often recovered most rapidly.
