Prevention is as easy as:


Remove all visible plants, animals, fish, and mud from your boat, trailer, or other equipment and dispose of in a suitable trash container or on dry land.


Drain water from boat, bilge, bladder tanks, live well, and bait containers, and any other locations with water before leaving the launch.

Dry your boat, trailer, and all equipment completely. Drying times vary depending on the weather and the type of material.
