In 2008, the purchase of a new sticker for owners of Maine-registered watercraft was automatically combined with the watercraft registration fee. The sticker, which now reads "Stop Aquatic Hitchhikers -- Preserve Maine Waters" and is physically attached to the Maine watercraft registration, has been required since 2002 for all motorized watercraft on inland waters. Owners of non-Maine registered boats will continue to be required to purchase and affix a separate nonresident sticker. 

An affirmation card reminds boaters and nonresident anglers of Minnesota’s aquatic invasive species laws. Watercraft owners and nonresident anglers must read and sign the affirmation during their regular license renewal, then keep it in their possession with their license. The affirmation, enacted by the Minnesota Legislature, is another positive step in the state’s proactive efforts to keep 95% of Minnesota lakes off the infested waters list.

All watercraft using Wyoming waters are required to display an Aquatic Invasive Species decal. Costs for the decal are $10 for motorized watercraft registered in Wyoming, $30 for motorized watercraft registered in other states, $5 for non-motorized watercraft owned by Wyoming residents, and $15 for non-motorized watercraft owned by non-residents. Non-motorized inflatable watercraft 10 feet or less in length are exempt. Fees collected for the AIS decal will be used to fund the AIS program in Wyoming along with a General Fund Appropriation. These fees will pay for outreach and education, watercraft inspections, and monitoring to prevent the spread of AIS into Wyoming.

Operators of watercraft not registered in Washington State, seaplanes, and commercial transporters of specified vessel types must purchase aquatic invasive species (AIS) prevention permits to help prevent the spread of AIS in Washington.

When purchasing online, you may select a preferred activation date. The permit will be valid for one year from that date.

In 2016, Nebraska implemented an Aquatic Invasive Species Stamp to fund programs aimed at combating aquatic invasive species. Boaters who register their motorized watercraft in Nebraska will notice a $5 fee added to their three-year boater registration fee. Boaters who register their motorized watercraft in any other state will be required to obtain a $15 Aquatic Invasive Species Stamp each year that they boat in Nebraska. This stamp is available for purchase online. A temporary stamp may be purchased at some state parks and recreation areas.

Motorboats and sailboats must have an ANS Stamp prior to launching vessels in Colorado (effective Jan 1, 2019).

Thank you for protecting our waters and contributing to conservation in Colorado!

California registered vessels using fresh water bodies within the state are required to display a “Mussel Fee Paid” sticker on the hull next to the current registration sticker. Paying the Mussel Fee does not entitle vessels to bypass inspections or fees for inspections conducted by individual reservoir owners or managers.

Beginning January 1, 2020, the Aquatic Invasive Species (AIS) Permit required for non-motorized boats 10 feet and longer will be replaced by a Waterway Access Permit. The AIS Permit will remain for out-of-state motorized boats and is included in Oregon boat registration fees.
