Recipient region (?) | Country: Netherlands LME: 22. North Sea References (not structured): Wolff WJ (2005) Non-indigenous marine and estuarine species in The Netherlands. Zool Meded Leiden 79:1–116 (and references therein). Comments: Introduction into The Netherlands: Kaas & Ten Broek (1942) and Van Benthem Jutting (1943) record that shells were observed a few times on the Dutch North Sea beaches, among others at Westkapelle (see Kaas, 1937). All finds date from after 1933. A live specimen was observed in the sluice dock of Ostend, Belgium, in the same period. This species had been imported earlier in France for human consumption. Since that time it is living along the French coast. Hence, the Flemish and Dutch specimens found before 1943 probably have been imported with French oysters. Wolff (unpublished) observed dead specimens in situ in a saltmarsh creek near De Piet in the Veerse Meer in 1961 after the closure of the Veerse Gat that year; these specimens were said to have been introduced deliberately by the Netherlands Institute for Fisheries Research for culture experiments. L.P.M.J. Wetsteyn (pers. comm., 2000) observed 5 live adult specimens at Hoge Kraayer in the Oosterschelde estuary in December 1995, and 1 adult specimen in the same estuary near Tholen in summer 2000. Aquasense (1998) records that it was 'introduced in the Dutch Oosterschelde estuary in the 1950s (pers. comm. L.P.M.J. Wetsteyn)'. Present occurrence in The Netherlands: Oosterschelde estuary. |
