Next time you renew your boat or other watercraft license, you will need to sign a card affirming you know what state law requires to prevent the spread of aquatic invasive species. The D-N-R’s April Rust says, “The majority of the folks in Minnesota know that, so it’s a good reminder, and then it’s a really good intro for those that are new to our laws” — that they might need to pay a little extra attention when they’re in Minnesota waters. Non-resident anglers also must sign the affirmation card when getting their fishing license. Rust notes if you just renewed your watercraft license, you don’t have to go in again right away, because renewals are every three years. State law requires boaters clean aquatic plants and prohibited invasive species from watercraft…drain lake or river water from all equipment and keep drain plugs out during transport…and dispose of unwanted bait in the trash, not in the water.
