Abstract |
The Ponto-Caspian predatory cladoceran Evadne anonyx G.O.Sars,1897 (Crustacea: Cladocera: Onychopoda) was first recorded in the eastern Gulf of Finland in the zooplankton samples collected during summer 2000. Most likely, E. anonyx invaded the gulf in the late 1990th from the Caspian Sea via the Volga-Baltic waterway with the ballast waters of ships. Between 2000 and 2004, the population densities of E. anonyx increased in the eastern Gulf of Finland more than 10-fold, indicating successful establishment of new Ponto-Caspian invader in the Baltic Sea. |
