Seafood Consumption Advisories

(Leer en Español)

While Galveston Bay is an outstanding place to fish, you need to be aware of seafood consumption advisories!

The Texas Department of State Health Services (DSHS) issues seafood consumption advisories when tests on fish and shellfish indicate there is an increased risk to human health from the presence of toxic pollutants.

This map shows the seafood consumption advisories that are currently in place in the Galveston Bay system and its tributaries. There are really four areas, each having its own set of affected species.
