Resumo

Two individuals of the Ponto-Caspian gammarid Dikerogammarus villosus (Sowinsky, 1894) were found in hand net samples in the southeastern part of the Baltic Sea near the Baltiysk harbor in June 2015. Until now D. villosus has not been observed in this region. The possible vectors and factors facilitating the process of spread of this amphipod in the southeastern part of the Baltic Sea are discussed.
