Classification Information



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

The status of shellfish growing waters 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, red tides, or the failure or inefficient operation of wastewater treatment facilities.

The current status of shellfish harvesting areas may be obtained from your local Texas Parks and Wildlife office or by calling, toll-free, 1-800-685-0361.

Texas Parks and Wildife posts the Regulations for Oysters and Other Aquatic Life on their Web site at www.tpwd.state.tx.us/publications/annual/fish/oysterreg/.
