Marine Pests

Following adapted from http://www.powerboat-world.com/Help-prevent-the-spread-of-Marine-Pests/40690/arc

What is a marine pest? A marine pest is any marine species of plant or animal that lives outside its natural range, and negatively impacts on the native fauna and flora.

Why are they a problem? Marine pests can:

- Damage your boat, increase fuel consumption and maintenance costs

- Deplete native fish stocks

- Destroy native marine habitats

- Release toxins and spread diseases that can harm humans and marine life

- Result in boating, anchoring and fishing restriction zones. How are they spread? Pests can be transported by any vessel – yachts, powerboats, ships, fishing boats, jet skis and even canoes.

There is a great risk that recreational boats and fishers will carry pests into pristine, pest free locations. Pests can easily be spread by 'hitching' a ride on your boat: Fouling on the hull Tangled in anchors, nets and gear Carried in plumbing systems, buckets and bilge water.

What can you do to avoid transporting marine pests on your boat? Check and clean your boat and gear before and after every trip. Remove any weeds, sediment, water or animals, and put them in the bin. Rinse your boat and gear with freshwater, and make sure everything is dry before you set off on your next trip. Choosing the correct antifouling paint for moored boats is also very important.
