Stop Aquatic Hitchhikers


The Stop Aquatic Hitchhikers! campaign is a call to action that empowers recreational users of aquatic resources in the United States and other countries to help stop the spread of harmful aquatic invasive species through outreach and partnerships.


You can help by taking the following actions:

  • Understand the threats of aquatic invasive species.
  • Learn to recognize aquatic invasive species and know where to look for them.
  • Clean, Drain and Dry all watercraft, trailer, motors, and gear every time, everywhere.
  • Never release fish, animals, or plants from one waterbody into another.
  • Report new sightings of aquatic invasive species to the appropriate authorities or use the USGS Sighting Report Form.
  • Help inform others about the threat of aquatic invasive species.
  • Encourage your elected officials to support measures that prevent aquatic invasive species.
