Vestigingsstatus Gevestigd
Zeldzaamheid Zeldzaam
Invasiviteit Potentieel invasief
Invasiviteit (toelichting) In and outside its native range, M. tuberculatus is a habitat generalist, adaptable to different environments; it benefits from human association (human commensal); is capable of securing and ingesting a wide range of food; is fast growing with high reproductive potential and reproduces both sexual as asexually (through parthenogeneses). It has high genetic variability and lives several years. In the Netherlands the species is still restricted to warmer water, greenhouses, aquaria and ponds, but already a local population was formed near a cooling water discharge plume of a chemical plant.

Natuurlijke verspreiding

  • Oceanië
  • Afrika
  • Verspreiding in Nederland
  • Noord-Holland
  • Overijssel
  • Verspreiding in Nederland (toelichting) A reproducing population was found in the Twenthe-canal 1992-1993. Empty shells have been found near IJmuiden and in hot-houses (a.o. in Leiden, Utrecht and Amsterdam). Apart from this, the species is often present in great numbers in the aquarium-trade and occuring in inside and sometimes outside ponds. At present the species seems to need higher water temperatures than presently occur in natural conditions in the Netherlands, although in the Twenthe canal the species already survived wintertemperatures. Being a common aquariumsnail, this species often hitch-hikes on aquarium plants. The aquariumtrade might cause a rapid spread when improved morphs, capable of surviving lower temperatures are set free together with water plants and aquariummaterials.

  • Volksgezondheid
  • Ecologische impact (toelichting) In the Netherlands there is thus far no obvious ecological impact. This species can have a negative impact i.e. reduce native biodiversity, because of its ability to monopolize resources, smother and outcompete native species, and change the gene pool, which results in selective loss of genotypes.
    Economische impact (toelichting) No economic impact has untill now been recorded from the Netherlands.
