Why Shellfish Licenses Matter
Shellfish licensing programs protect estuarine ecosystems, ensure sustainable harvests, and fund water quality monitoring. Shellfish are filter feeders that are extremely sensitive to pollution — licensing programs help track harvest pressure and fund closures when water quality is compromised. Whether you're digging littleneck clams in Maine, harvesting oysters in the Chesapeake Bay, or gathering mussels on the Oregon coast, a license supports the health of these shared resources.
