Texas Shellfish Harvest Area Viewer

Small preview snapshot of Texas Shellfish Harvest Area ViewerThe Texas Shellfish Harvest Area Viewer is an interactive map that allows users to identify shellfish harvest areas, shellfish harvest area boundary markers, bay water monitoring stations, and private oyster leases throughout the Texas Gulf Coast. 

The status of shellfish harvest areas in Texas estuaries is subject to change by the Texas Department of State Health Services at any time. These changes may be due to high rainfall and runoff, flooding, hurricanes and other extreme weather conditions, major spills, harmful algal blooms, or the failure or inefficient operation of wastewater treatment facilities.

The Texas Parks and Wildlife Department may also take actions to close shellfish harvest area(s) due to shellfish resource concerns or enforcement issues.

Because the status of shellfish harvest areas may change daily, it is important that commercial and recreational shellfish harvesters verify the status of the shellfish harvest areas before harvesting shellfish. The status of shellfish harvest areas can be obtained from the Shellfish Status Web page, the Seafood and Aquatic Life Group at (512) 834-6757 or by calling, in state only, toll-free, (800) 685-0361.

For questions about the Texas Shellfish Harvest Area Viewer, please see the step-by-step instructions below or contact the Seafood and Aquatic Life Group at 512-834-6757 or seafood.regulatory@dshs.texas.gov.

Additional Information about Shellfish Harvest Areas

Molluscan shellfish are defined as oysters, clams, and mussels. All shellfish in Texas waters must be harvested from approved or conditionally approved harvest areas as designated on the viewer or maps. 

The Texas Parks and Wildlife Department is responsible for commercial (including private oyster lease) and recreational oyster regulations (e.g., seasons and length and possession limits).

All coastal and inland waters not specifically designated as Approved, Conditionally Approved, Prohibited, or Restricted are classified as Prohibited and are closed to the harvest of molluscan shellfish.
