It is essential that the species be detected, identified or isolated as soon as possible, so please report sightings to the appropriate authority.

How to prevent

PREVENT. CLEAN. TREAT. The first defense against aquatic invasive species is prevention. To protect our waters and industries, we ask boaters to do their part in preventing the spread of invasive species.

ANTI-FOULING
  • Apply anti-fouling* paint and renew it within the manufacturer's suggested time frame.
  • Use manual cleaning together with anti-fouling paints. Research shows that manual cleaning alone can actually increase the rate of fouling, unless followed by an application of anti-fouling paint.
  • Dispose of fouling on land as per normal compost.
*Fouling refers to the buildup of debris and possible AIS on the hull of a boat. Fouling can negatively affect your boat‚ fuel efficiency, speed and cause increased maintenance costs.

HULL MAINTENANCE
  • Keep the boatyard clean to prevent waste from entering the aquatic environment.
  • Capture paint scrapings and residues by using shrouding, tarps and drop cloths.
  • Contain all waste and run-off when performing hull maintenance on tidal grids or at any facility.
  • Immediately report all spills to the facility manager.
BEST PRACTICES
  • Inspect and clean your boat regularly.
  • Clean your boat before you leave port.
  • Remove any plants or animals. Dispose of on land as per normal compost.
  • Drain water from your boat motor, bilge, and wells. Let equipment dry completely if possible.
  • Don't take on or release ballast water in port or near aquaculture facilities.
  • Boats and trailers can be sprayed down with a hand-pump garden sprayer containing fresh water or five per cent acetic acid (vinegar). Safety glasses should be worn when applying vinegar. Equipment should be permitted to dry for a minimum of an hour before entering another body of water.
MOVING BOAT BY TRAILER
  • Drain water from the boat and motor and any other areas that hold water.
  • Remove plant fragments and other organisms from boat and trailer and discard on land as per normal compost.
  • Rinse the boat and trailer thoroughly with water and allow to dry prior to entering a new water body.
NEVER put any shellfish you buy or shells, seaweed, bait and driftwood collected from the beach back into the ocean!
  • Have a waste container on your boat. The best policy is to bring back what you took out.
  • Avoid taking plastic wrap and bags while out on your boat‚ these are the most common items lost overboard.
  • Dispose of unwanted bait well offshore. Gut fish and dispose of waste well offshore or consider land disposal.
  • Plan ahead and know the rules for sewage management and discharge properly. Pump it‚ don't dump it!
  • Report any fuel spills immediately to the fuel station operator, marina operator and local regional council.
  • Rinse the boat and trailer thoroughly with water and allow to dry prior to entering a new water body.
