The first specimens of the Asian prawn Palaemon macrodactylus Rathbun, 1902, including ovigerous females, were identified in estuarine water bodies along the Romanian coast during early September 2009, in large numbers compared to the native prawns Palaemon elegans Rathke, 1837 and Palaemon adspersus Rathke, 1837. Examination of archived samples backdated the first occurrence of P. macrodactylus in the Black Sea to 2002. The supposed vector of introduction is via ballast water, from ships travelling from Rotterdam. Native to the seas of Japan and Korea, P. macrodactylus was first introduced in California in the 1950s, Australia in the 1970s and later to Britain, parts of continental Europe and Argentina. The Asian prawn already has wellestablished populations in the Romanian Black Sea and, taking into consideration the invasion record and the ecology of this species, it is very likely that it will successfully invade the whole of the Black and Azov Seas and the adjacent estuaries, deltas and limans.
