The Harte Research Institute is doing the work most anglers never see — and the fish you chase depend on it.

Every cast you make along the Texas coast taps into a whole ecosystem you may never see.

Beneath the surface, reefs are doing the quiet work of creating habitat that supports marine life, including the fish we chase.

As Geret DePiper, Endowed Chair for Resource Economics at the Harte Research Institute (HRI) at Texas A&M University-Corpus Christi, puts it: "Our enjoyment, way of life, and economy depend on the Gulf and all that it holds."

At HRI, researchers are working to understand and protect four distinct types of reefs found in Texas waters that are critical to healthy marine life. Each plays a role in keeping the Gulf productive, resilient, and enjoyable for all.

Four Kinds of Reefs Off the Texas Coast

Coral Reefs

The most well-known of these are coral reefs. While most coral reefs prefer shallow waters, the Flower Garden Banks National Marine Sanctuary reef system lies in deeper waters about 100 miles off our Texas coast. Home to some of the most abundant and resilient corals on this side of the world, the reef is offering researchers insights that could help protect vulnerable species elsewhere.

Serpulid Worm Reefs in Baffin Bay

Closer to shore, in the hypersaline waters of Baffin Bay, lesser-known but equally important reefs are built by serpulid worms. These tiny organisms create rock-like structures over thousands of years. Their reefs provide habitat for fish, crabs, and other species that fuel the food chain.

Artificial Reefs

Artificial reefs add another layer to the story. Many anglers are familiar with sunken ships as fishing hotspots, but decommissioned oil and gas platforms also serve as thriving reef systems. With proper management, these structures become stable foundations for marine life and often develop into highly productive fishing areas over time.

Oyster Reefs

Then there is the backbone of the Texas coastal ecosystem: oyster reefs. Found in shallow bays and estuaries, oyster reefs are some of the most valuable habitats in the Gulf. They provide shelter for juvenile fish and forage species, stabilize shorelines, and improve water quality. A single oyster can filter up to 50 gallons of water each day, helping keep the bays cleaner and healthier for everything that lives there.

Sink Your Shucks: Rebuilding Oyster Reefs

While the reefs are pretty impressive, they can't defend themselves, and that is where restoration comes in.

Through the Sink Your Shucks™ program, HRI is working to rebuild oyster reefs across Texas bays. The idea is simple: reclaim used oyster shells from restaurants and festivals, then return them to the water where they can serve as the foundation for new reefs. Those shells become homes for spat, or baby oysters, that attach, grow, and eventually form new reef structures.

Since the program began, more than 3 million pounds of shell have been recycled, restoring over 45 acres of oyster reef habitat in the Mission-Aransas Estuary. Volunteers help build reefs along the shoreline in St. Charles Bay, while larger-scale efforts use barges to place shells in deeper waters. These efforts create reefs that grow quickly and remain protected from harvesting. It is a direct way to give back to the resource that gives so much.

The fishing we enjoy in the future depends on the decisions we make now. Healthy reefs support a healthy Gulf and ensure that future generations can experience the same early mornings, tight lines, and stories worth telling. Whether you fish, dive or simply cherish these waters, you are already part of the story. Want to be part of what comes next?
