Aquatic Invasive Species
Missouri AIS
Sticker Requirements 2026
Aquatic invasive species sticker and watercraft inspection requirements for Missouri boaters. Missouri does not require a paid AIS sticker. Missouri waters face AIS threats from Asian carp, zebra mussels, and aquatic plants. MDC law requires all boaters to drain water from boats, live wells, and bilges before leaving any water access. It is illegal to release non-native fish, including Asian carp, into Missouri waters.

How to Comply with AIS Requirements in Missouri
Follow these steps to stay compliant with Missouri's aquatic invasive species regulations:
1
Check Sticker & Inspection Requirements
Missouri does not currently require a mandatory AIS sticker or inspection program. However, all boaters are strongly encouraged to follow Clean, Drain, Dry practices.
2
Purchase Your AIS Sticker (If Required)
No paid AIS sticker purchase is required in Missouri at this time. Check back annually as state requirements can change.
3
Practice Clean, Drain, Dry
Before leaving any boat launch — and before launching on a new water body — clean all visible aquatic plants and debris from your boat, trailer, and equipment. Drain all water from bilges, livewells, bait buckets, motor, and other water-holding compartments. Allow the boat to dry for at least 5 days before launching on a different water body, or use a high-pressure, hot-water wash.
4
Cooperate with Inspection Stations
If you encounter a voluntary inspection station in Missouri, stopping is strongly encouraged even if not required. Inspectors can identify and remove invasive species from your equipment that you may have missed.
Noncompliance fine: Fines under MDC regulations for transporting AIS.
