When You Fish from Shore or While Wading:

  • Clean all visible aquatic plants, animals, and mud from waders and hip boots
  • Scrub any visible material off footwear with a stiff brush
    • To further reduce the risk of spreading AIS, use rubber-soled instead of felt-soled footwear
    • Dispose of unwanted bait, and fish parts in the trash. When keeping live bait, drain bait container and replace with bottled water or de-chlorinated tap water
  • Transport fish on ice—be prepared, bring a cooler

Felt-soled Footwear

While they provide a good grip in slippery places, felt-soled footwear can pick up AIS, allowing the invaders to hitchhike on shoes from one stream to another.

When You Use a Seaplane:

Before entering the aircraft:

  • Pump floats (note: this will help avoid spreading fish diseases)
  • Inspect for and remove all aquatic plants and animals from the floats, wires or cables, and water rudders

Before take-off:

  • Avoid taxiing through heavy surface growths of aquatic plants
  • Raise and lower water rudders several times to clear off plants

After take-off:

  • Raise and lower water rudders several times to free aquatic plant fragments while over the waters you are leaving or while over land
  • If aquatic plants remain attached, return to the lake and remove the plants

  • Turn off motor
  • Clean the steering nozzle and intake grates
