Beneath the surface off Delaware’s coast, entire underwater communities are taking shape.
For World Reef Awareness Day, we’re highlighting the important role reefs play in supporting marine life—and that includes Delaware’s artificial reefs. Through the Division of Fish and Wildlife Artificial Reef Program, a network of reef sites has been created offshore using specially selected materials that provide habitat for fish, crabs, mussels, and other marine organisms.
Over time, these structures become thriving ecosystems, attracting species like black sea bass, tautog, and summer flounder while also creating exciting opportunities for fishing and diving.
Reefs do more than gather fish in one place. They provide shelter, feeding areas, and surfaces for marine life to grow, helping support biodiversity in Delaware’s coastal waters. As these underwater habitats develop, they become living examples of how marine ecosystems can grow and change over time.
While most people never see these reefs firsthand, there’s an entire world of activity happening below the waves.
