  8. Inhibit Zebra Mussel Attachment • Expose boat hulls to high water velocity • Run engines frequently to kill veligers • Raise lower units out of water • Use boat lift • Treat boat hulls and lower units with antifouling coatings 8

  9. Antifouling Coatings 9

  10. Copper-based Paints • Effective antifoulants • Generally available over-the-counter • Effective on fiberglass, wood, and steel • Not recommended for aluminum 10

  11. Tributyltin (TBT)-based Paints • Effective antifoulants • Highly toxic • Require a pesticide applicator permit • Use primarily on aluminum boats 11

  12. Comparison of Antifouling Coatings • Copper-based paints – season-long deterrence • TBT-based paints – season-long deterrence • Antifouling engine sprays with TBT – 10 weeks • Oil-based coating – no measurable protection 12

  13. CAUTION • Use paints that release active ingredients only when they’re submerged 13

  14. Application of Antifouling Coatings • Apply in spring prior to launching • Use tar-based undercoating to improve boat performance • Revitalize intact coatings 14

  15. Protect engines, too! • Antifouling paint • In-line strainers 15

  16. CAUTION • Before using any antifouling coating, check about local regulations. 16

  17. Remember……. 17

  18. 18

  19. Also Be Sure To….. • Check marine toilet outflows • Check drain plugs • Check bait well and live well inflows and outflows • Wash down intakes 19

  20. Help Slow the Spread 20

  21. Remove all aquatic plants and animals from the boat, motor, and trailer. 21

  22. Check anchors and other equipment for mud or plants. 22

  23. Drain lake or river water from bait bucket, livewell, and bilge. 23

  24. Dispose of unwanted bait on shore or in the trash. 24

  25. Rinse boat and equipment with high-pressure or 104 degree F water, especially if moored for more than a day. 25

  26. OR,Dry all equipment for at least 5 days under good drying conditions. 26
