Through tedious research, study, and lots of trial and error, the Oyster Castle® was born. The Oyster Castle® is an easily deployed, specialized manufactured concrete unit using an environmentally friendly, certified blend of proprietary material conducive to attracting and fostering oyster settlement, attachment, and growth.
