Vestigingsstatus Niet gevestigd
Zeldzaamheid Lokaal
Invasiviteit Potentieel invasief
Invasiviteit (toelichting) F. delicia was described in 2000 from North America (Gulf of Maine). Soon afterwards it was found in Alaska and San Francisco. The species was introduced in France (Brittany and Normandy; Granville; Pléneuf-Val-André). On the Belgian an Dutch shores this species is regularly found on floating objects (plastics). The first indigenous records in the Netherlands are from 2005. The last few years this species seems to be spreading rather fast along the Dutch and Belgian coasts. At general the species is believed to spread accidental with deliberate translocations of fish or shellfish (Katsanevakis et al. 2011).

Natuurlijke verspreiding

  • Groningen
  • Noord-Holland
  • Zuid-Holland
  • Zeeland
  • Verspreiding in Nederland (toelichting) Fenestrulina delicia was found indigenous for the first time in the Netherlands in 2005 (several colonies on empty valves of Mytilus edulis at Sas van Goes (Blauwe 2008)). Recently the species has started to spread through the Eastern Scheldt and the North Sea (for instance settling on supporting bases of windmills). It has been found near the Borkumse Stenen, now the most northern observation of this species in Europe. Along the coasts of Belgium and The Netherlands the species nowadays is regularly found on beached plastics and other floating objects (Van der Wende 2011). It is not clear what causes this rapid spread.
    Habitats
  • Mariene habitats
  • Estuaria en brakwatergebieden
  • Wijze van introductie Aangroei op scheepsrompen
    Ecologische impact (toelichting) In the Netherlands colonies first were found on empty shells of the indigenous mussel Mytilus edulis. If in the future colonies starts to settle on other substrates, artificial objects, ship’s hulls, wood then the species could well prove to be a fouling organism. It might overgrow other species of bryozoa or at least compete with them for space and resources. Also in aquaculture the species migh become a nuisance by growing on shells of mussels and oysters and rendering them to be less attractive for sale, or even have a negative impact on growth. At the moment this species would not be expected to give particular cause for concern (ICES, 2012).
    Economische impact (toelichting) See also ecological impact. The status of impact is not yet clear. It might well prove to become a fouling species with some impact on aquaculture.
