What to Look For

Aquatic Invasive Species (AIS) are species that enter into new ecosystems and spread, causing damage to native species and their habitants. These species are spread beyond their normal distribution, often as a result of human activities, and can threaten valuable environmental, agricultural or personal resources by the damage they cause.

It can be difficult for the untrained eye to tell from the surface if a boat is a risk or not. The SAFEST RULE OF THEM IS TO ENSURE YOUR BOAT NEVER CARRIES MORE THAN A SLIME LAYER and ideally this is regularly brushed or wiped off.

And you should always REMOVE ALL VISIBLE FOULING including mussels, barnacles, seaweed, etc from your boat. Even if you do recognize what's on your boat, remove it!

On any one day, an estimated 3,000 species are transported in the ballast water of ocean-going vessels around the world. So don't forget to clean those "not-so-easy-to-reach" areas on your vessel! Such areas are:
  • keel and stabilizers
  • intakes and outlets
  • propellers and shafts
  • rudders and casings
  • through-hull fittings
  • earth plates, transducers and areas where anti-foul has not been applied such as where the hull has rested during the last painting
  • anchors and anchor wells
Aquatic Invasive Species will often out-compete, prey upon, or smother native species. They are one of the leading threats to biodiversity, and they cost millions of dollars to control, and cause substantial revenue losses for local fisheries. HELP US PREVENT THE SPREAD!
