How boat owners can help stop the spread of marine pests

Check. Clean. Dry.

Vessel owners can help stop the spread of marine pests by always remembering to check, clean and dry.

  • Check your vessel and equipment for any attached animals and plants — remove them. Do not return marine pests to the water.
  • Clean your vessel and equipment after use with freshwater.
  • Dry your vessel and equipment thoroughly before moving to a new location.

Application of appropriate anti-fouling coatings can help minimise the build-up of biofouling on underwater surfaces.
