| Abstract |
Gammarus tigrinus SEXTON, 1939 has been found in April 1996 in the great basin of 'Muisbroek', a recreation area at Ekeren, north of the town of Antwerp (figures 2 and 3). The specimens were discovered between algae, growing upon stones and a floating landing-stage (water depth f 0,5 m). The pond is filled with freshwater (chlorides : f 66 mgil). The present population of Gammarus tigrinus originates most probably from the Netherlands, where the species is common in the great rivers. Specimens must have been introduced during a restocking of fish, by waterfowl or even divers, who had visited Dutch waters before. |
