| Abstract |
Since 2000 three Ponto-Caspian invaders have been found in canals in the province of Antwerp (N.E.-Belgium): the freshwater polychaete Hypania invalida (Grube, 1860), the triclad Dendrocoelum romanodanubiale (Codreanu, 1949) and the freshwater isopod Jaera istri Veuille, 1979. Staff members of the 'Vlaamse Milieumaatschappij (Flemish Environmental Agency) collected these species on artificial substrates (nets filled with broken bricks). H. invalida had been discovered before in Belgium in the river Meuse in 2000 (Vanden Bossche et.al., 2001). D. romanodanubiale and J. istri were never recorded before in Belgium. Before its discovery in the Belgian Meuse in August-September 2000, H.invalida had already been found in May 2000 in the Albert Canal at Genk in the province of Limbourg. Between 2001 and 2003, the polychaete was sampled at several stations of the Albert Canal and its adjacent canals in the provinces of Antwerp and Limbourg. Here, it often is accompanied by D. romanodanubiale and J. istri. In 2003 the polychaet had also been encountered in the Sea canal Brussels - Scheldt in the province of Antwerp. The discontinuous distribution indicates that navigation plays an important role in the dispersal of the species. Other Ponto-Caspian species such as Dikerogammarus villosus (Sovinskij, 1894) are either already present in the canals or soon to be expected there. Some of these species will probably also invade the Scheldt basin. |
