2011 EcoSystem by Walter Marine
The Ecodiscs are by Reefmaker from David Walters. The fossilized and recycle oyster shell Ecodisc Ecosystem was designed just for Deadman's Island project and the first to be permitted in the State of Florida. This Oyster shell Ecodisc was created to provide a natural substrate for oyster spat. Little Flower Catholic School students created the first prototype from this idea.
