Shellfish Status Information
We can change the status of shellfish harvest areas in Texas estuaries at any time. These changes may be because of:
High rainfall and runoff,
Hurricanes and other extreme weather conditions,
Harmful algal blooms, or
The failure or poor operation of wastewater treatment facilities.
We may also close shellfish harvest area(s) due to shellfish resource concerns or enforcement issues.
Shellfish Harvesting Areas Maps
Molluscan shellfish are as oysters, clams, and mussels. All shellfish in Texas waters must be harvested from approved or conditionally approved areas as designated on the maps.
This page is meant to help commercial and recreational shellfish harvesters get the information they need. Be sure to check this page for the latest safety and regulatory information because the status of harvest areas may change every day.
All coastal and inland waters not specifically designated as “Approved,” “Conditionally Approved,” “Prohibited,” or “Restricted” are classified as “Prohibited”. Those are closed to molluscan shellfish harvesting.
