Shellfish & Clamming
Wisconsin Shellfish License 2026
Requirements, fees, and regulations for harvesting clams, oysters, and mussels in Wisconsin. Wisconsin borders Lake Michigan and Lake Superior but has no open recreational shellfish season. Native freshwater mussels in Wisconsin's rivers and Great Lakes shoreline are broadly protected under state and federal Endangered Species Act provisions. Invasive zebra and quagga mussels have severely impacted native populations.

Step-by-Step
How to Get a Shellfish License in Wisconsin
1
Verify Open Areas
Before purchasing a license, check that shellfish beds in your target area are currently open. Wisconsin Dept. of Natural Resources maintains an up-to-date list of approved harvesting areas. Water quality closures can occur quickly after rain events.
2
Purchase Your License
Purchase online at Wisconsin Dept. of Natural Resources, or in person at authorized license agents throughout Wisconsin.
3
Know Your Limits
Review the current daily bag limits for your target species.
Size minimums also apply — undersized shellfish must be returned to the water. Keep your license on your person while harvesting.
4
Harvest Responsibly
Use appropriate gear (clam rakes, oyster tongs) and handle shellfish carefully to minimize disturbance to the surrounding habitat. Replace any rocks or substrate you disturb and never harvest from closed or unclassified waters.
Requirements
Wisconsin Shellfish License Requirements
Harvest of native freshwater mussels is prohibited. State and federal ESA protections apply.
