How to Get a Shellfish License in Missouri
1
Verify Open Areas
Before purchasing a license, check that shellfish beds in your target area are currently open. Missouri Dept. of Conservation 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 Missouri Dept. of Conservation, or in person at authorized license agents throughout Missouri.
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
Missouri Shellfish License Requirements
