Shellfish Harvest Area Status and Maps

Status of Shellfish Harvesting Areas 11.29.2024

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,  

• Flooding,  

• Hurricanes and other extreme weather conditions,  

• Major spills,  

• 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.

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). 

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. 

We will provide a hard copy of the shellfish harvest area(s) you are interested in if you can’t download a copy.
