Drie Ponto-Kaspische inwijkelingen worden sinds 2000 aangetroffen in enkele kanalen in de provincie Antwerpen: de zoetwaterpolychaet Hypania invalida (Grube, 1860), de platworm Dendrocoelum romanodanubiale (Codreanu, 1949) en de Donaupissebed Jaera istri Veuille, 1979. Personeel van de Vlaamse Milieumaatschappij verzamelde de drie soorten, vaak sam...

De Donauplatworm (Dendrocoelum romanodanubiale), Donaupissebed (Jaera istri) en de polychaete worm Hypania invalida, worden pas sinds de eerste jaren van dit millennium in Antwerpse kanalen gesignaleerd (Vercauteren et al. 2005) en zijn nu alle tot in de Kempen doorgedrongen. Hun voorkomen in de plas is geenszins verwonderlijk gezien de open verbinding met het kanaal, het bootverkeer naar de jachthaven en de aanwezigheid van geschikte omstandigheden (waterbeweging, zowel zandig substraat als stenen, kaaimuren, enz.). ...

Résumé
La crevette mysidacée Limnomysis benedeni a été trouvée en 2005-2006 dans l’étang le plus grand du domaine provincial «Prinsenpark» à Retie (province d’Anvers), le Grote Vijver ou Gertrijvijver. Il s’agit de la première découverte de L. benedeni en Belgique. L’espèce a été localisée le long de la rive septentrionale. Dans la période septembre 2005 - avril 2006, L. benedeni se trouvait exclusivement tout près de l’échappement, à un endroit peu profond où le fond et la rive sont couverts de blocs de béton. En août 2006, les mysidacés ont été retrouvés dans la partie ombragée de la rive, entre Zannichellia palustris et des branches immergées des plantes rivicoles. La présence de cette espèce exotique résulte du fait que La Meuse approvisionne la majorité des étangs du Prinsenpark via le Canal de Bocholt-Herentals. La Meuse et ses canaux sont des réservoirs importants de ces macro-invertébrés exotiques.
Summary
The mysid Limnomysis benedeni has been found in the Grote Vijver (Great Pond) of the Provinciaal Groendomein Prinsenpark in Retie (Province of Antwerp, Northern Belgium) in 2005-2006. It is the first discovery of L. benedeni in Belgium. The mysid was discovered along the north bank of the pond. From September 2005 until February 2006 L. benedeni seemed to be confined to the open, shallow water and adjacent bank, covered with concrete stones, near the outlet of the pond. However, in August 2006 the mysids were found along the shaded part of the bank between Zannichellia palustris and overhanging littoral plants. The presence of this alien species can be linked to the inlet of water from the neigbouring Canal Bocholt-Herentals into the ditches and ponds in the Prinsenpark. The canal receives its water from the Meuse. The Meuse and its connecting canals are known as important reservoirs of alien macro-invertebrates.
... He stated that at least 13 macrocrustaceans had invaded Belgium. Other studies revealed that exotic molluscs (Dreissena polymorpha (Pallas, 1771), Potamopyrgus antipodarum (Gray, 1843), Corbicula fluminea (Müller, 1774), C. fluminalis (Müller, 1774)), annelids (Hypania invalida (Grube, 1860)) and flatworms (Dendrocoelum romanodanubiale (Codreanu, 1946) and Girardia tigrina (Girard, 1850)) have invaded Flemish watercourses (SWINNEN et al., 1998; NGUYEN & DE PAUW, 2002; VERCAUTEREN et al., 2005). For marine and brackish waters in Flanders, an overview of all alien taxa has been presented by KERCKHOF et al. (2007). ...
... Also for Cladocera, a group of microcrustaceans, an overview was given of the indigenous as well as non-indigenous species occurring in Flanders (LOUETTE et al., 2007). The proximity of the sea, the interconnection between different waterways, the high degree of canalisation, the boat transport and the presence of harbours make Flemish watercourses susceptible for aquatic invasions (VERCAUTEREN et al., 2005). ...
... In several sites, including those in the Zuid-Willemsvaart canal (Fig. 3 ), D. villosus also replaced G. tigrinus, however, in most sites both species still seemed to be able to co-exist.

Biological invasions of freshwater macroinvertebrates are gaining more and more interest because the ecological and economical impact of some of these species is high. Since crustacean taxa appear to be successful groups invading new areas, an inventory of the macrocrustaceans in Flanders was made. At least 22 freshwater macrocrustacean species have been reported from Flemish water bodies. A detailed study of six canals, one small artificial watercourse and one natural river in the eastern part of Flanders revealed that invaders such as Dikerogammarus villosus, Gammarus tigrinus and Chelicorophium curvispinum are already quite common. Especially D. villosus is currently rapidly expanding and has a serious impact on native and other exotic gammarid species. Based on observations in neighbouring countries, several additional species are expected to arrive in the near future. A follow up of the alien species together with a monitoring scheme to detect new incoming species is valuable to estimate the size of the problem and to be able to closely follow their ecological and economical impact.

Biological invasions of aquatic macroinvertebrates are gaining interest because of their potential for significant ecological and socio-economic impacts (positive and negative). In the present study, an inventory was made of the alien macroinvertebrates occurring in Flanders (northern Belgium) based on extensive existing collections of biological samples and supplemented with our additional sampling programs. Fresh and brackish waters as well as the Belgian coastal harbours, situated at the interface of the marine environment, were investigated. Over 2,500 samples containing alien macroinvertebrates were identified to species level, which allowed us to accurately map their distribution in Flanders. Alien macroinvertebrates are widespread and abundant in many watercourses in Flanders. Four new macroinvertebrate species for Flanders were discovered: Procambarus clarkii (Girard, 1852), Echinogammarus trichiatus (Martynov, 1932), Synurella ambulans (F. Müller, 1846) and Laonome calida Capa, 2007. Fifty-two alien macroinvertebrates were encountered in fresh and slightly brackish surface waters, and 21 alien species were reported for the Belgian part of the North Sea and its adjacent estuaries. Most alien macroinvertebrates collected were crustaceans and molluscs. Alien species found in fresh and brackish water mainly originate from the Ponto-Caspian area and North America; fewer species originated from Asia and South- and East-Europe. The major pathways were probably shipping and dispersal through canals. Based on observations in neighbouring countries, several additional species are expected to arrive in the near future. Follow-up work is needed to assess the ecological and economic impacts of existing alien macroinvertebrates, and a monitoring program is needed to detect new incoming species.
