Impacts

Pathways

  • Inhabits shallow subtidal area below low water mark often attached to oysters and mussels
  • In France has altered benthic habitat through smothering of sediment beds with densities of 000’s/m2 that trap suspended silt, faeces and pseudofaeces
  • Exclude other bivalves including oysters to whose beds they are a serious threat.
  • Also a major threat to other protected species
  • Contaminant of oyster spat.
  • Hull fouling

Management

Prevention

Take measures to ensure there is no transport of bilgewater between waterbodies and inspect boat hulls, trailers, outboard engines, I/O drive legs, water intakes, exhausts and trailers for fouling/ infestation before moving between waterbodies. Avoid importation of contaminated oyster spat or other products or equipment.
