Abstract

The invasive Chinese mystery snail Bellamya chinensis (Gastropoda: Viviparidae) expands its European range to Belgium.

Abstract

In this paper we report the first Belgian records of the invasive Chinese mystery snail Bellamya chinensis. A walkover-survey along the Laak, a small lowland river, yielded a total of 20 live B. chinensis. The presence of both juvenile and adult individuals, with a shell height ranging from 16.6 to 47.5 mm, indicates that the species is firmly established. The most probable source of introduction is a nearby garden center that specializes in ornamental fish and plants for garden ponds.
