Abstract
    In order to trace the introduction history of the western Pacific species Heterosiphonia japonica to and within Europe, information on distribution pattern of the species in Europe, oyster import and shipping activity has been compiled and analyzed. Additionally survival of fragments of H. japonica during a simulated journey in ballast water from Asia (Korea) to Europe (France) has been observed. The species was first recorded in Europe near an oyster culture area in Brittany (France) in 1984. Since then, it has spread quickly in Europe. The first introduction into Europe and secondary dispersal in southern Europe has most likely been trough movement of the Pacific oyster Crassostrea gigas. However, survival of H. japonica in temperatures varying from 14 to 28 degrees during a simulated 28-days journey in ballast water was demonstrated, and an introduction by ships from the Pacific Ocean may thus be considered as possible. Spreading of the species in the North Sea area and Scandinavia is most likely due to transport by ships, e.g. as attached to ships hulls, as fragments in ballast water or entangled e.g. in fishing gear.
