Impact DescriptionBlueback Herring in a South Carolina reservoir ate mostly zooplankton, including Bosmina sp. (13-78% of biomass), and Cyclapoid Copepods (12-78%). Blueback Herring diets differed significantly from diets of Threadfin Shad, which consumed proportionately more Bosmina sp. and rotifers; however, if food resources are limited there could be competition between these species.
