Introducing Nuisance Species into Pennsylvania Waters

Introducing nonnative species into Pennsylvania waters can upset the balance of the ecosystem, thereby harming the environment. Aquatic nuisance species, such as zebra mussels, quagga mussels, milfoil, and hydrilla, most often spread between waterways by hitching a ride on vessels and trailers. When transplanted into new waters, these organisms proliferate, displacing native species and damaging the water resource.

Stop the Spread of Nuisance Species!

To prevent spreading aquatic nuisance species:

  • Inspect your vessel and trailer, and remove any plants and animals you see before leaving the area.
  • Drain your motor, live well, and bilge on land before leaving the area.
  • Empty your bait bucket on land. Never release live bait into a body of water or release aquatic animals from one body of water into another.
  • Rinse your vessel, propeller, trailer, and equipment.
  • Air-dry your vessel and equipment for as long as possible.
