Working for the U.S. Fish and Wildlife Service, I have used social marketing to design, implement and evaluate a national public awareness and partnership campaign targeting recreational users of our aquatic resources to raise their awareness about aquatic invasive species and to empower them to become part of the solution in preventing the spread of these harmful species through their activities. The campaign is called Stop Aquatic Hitchhikers! and the campaign's web site is www.protectyourwaters.net
