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.

Physical Control

Mechanical removal is possible.
