Specimen ImpactIntroduction of blueback herring reulted in the elimination of large-bodied zooplankton such as Leptodora, Epischura, Mesocyclops and Daphnia, while small-bodied zooplankton such as Cerio-daphnia, Tropocyclops and Bosmina increased. There appeared to be little change in lengths of the zooplankton in the reservoir after herring introduction, but the community shifted from cladoceran to copepod dominance.
