As of September 1, 2013, it is illegal to cause or allow any rooted seagrass plant to be uprooted or dug out from the bay or saltwater bottom by a submerged propeller within the coastal waters of the state of Texas. Violation is a Class C Misdemeanor subject to a fine of up to $500.

Submerged seagrass meadows are a dominant, unique subtropical habitat in many Texas bays and estuaries. These marine plants play critical roles in the coastal environment, including nursery habitat for estuarine fisheries, a major source of organic biomass for coastal food webs, effective agents for stabilizing coastal erosion and sedimentation, and major biological agents in nutrient cycling and water quality processes.
