ReefBLK℠ is a system for using living oyster reef panels as components of structures designed for a broad range of engineering applications in estuarine areas. Erosion control structures, canal plugs and water control structures can be built that not only are functional, but also enhance the environment. The structures themselves become living reefs that provide a habitat for a large variety of fish. The reefs produce shell that washes on shore to form beaches. The combination of shell beaches and reef fish then form a prime habitat for shore birds.

The ReefBLK℠ technique results in more rapid formation of reefs than through natural reef formation. The reefs enhance aquatic and avian habitat diversity, recreational and commercial fisheries productivity, and provide a natural management tool for combating coastal erosion. The process has potential applications anywhere oyster will grow, along the shores of lakes and bays, around islands, and along the banks of streams and canals. The ReefBLK℠ system is patented. It was developed with the support of a team of experienced scientists and it has been proven through successful installation in coastal waters.
