The invasive zooplankter Cercopagis pengoi was recorded for the first time in Lake Erie during August 2001 following previous colonization of Lakes Ontario and Michigan. Cercopagis pengoi (Cladocera: Cercopagidae) is from the Ponto-Caspian region of Eurasia, as is a previous cercopagid invader, Bythotrephes longimanus. Cercopagis tolerates a wide range of salinities and temperatures, has many life history traits characteristic of a successful invader, and has previously invaded the Baltic Sea Cercopagis may affect native zooplankton populations and fish populations through both predation and competition, although the extent of these interactions is not yet known. More research regarding basic life history traits and ecology of Cercopagis is needed to assess the role it will play in Lake Erie.
