Stop Aquatic Hitchhikers (Source: Wisconsin Natural Resources Magazine, April 2013):
• Prevent the spread of invasive species and fish diseases by not transferring water, fish, fish eggs or other aquatic organisms between waterways.
• At the boat launch, inspect your boat, trailer and equipment and remove any plants, sediment and animals.
• On land, drain all water from the motor, live well, bilge and transom well.
• Empty your bait bucket into the trash, not the water.
• After leaving the launch wash your boat, tackle, trailer and other equipment with hot (104 degrees) tap water or a high-pressure sprayer. Or, allow your boat and other equipment to dry thoroughly in the sun for at least five days before moving to another body of water - some invasive species may not be visible to the naked eye and can survive for long periods of time out of water.
• If you had your watercraft where a fish disease called viral hemorrhAgic septicemia (VHS) has spread (check with your local DNR), disinfect your boat before moving to an uninfected lake.
