A portable concrete reef substrate tile, wherein the concrete reef substrate tile feeds developing embryonic oysters attached to the concrete reef substrate tile's surface, wherein the concrete reef substrate tile comprises vertical columnar extrusions or projections supported by buttresses and extending from one face of a base;
- wherein the vertical columnar extrusions or projections comprise crevices or cavities and are spaced to slow water flow and mitigate wave movement, create a marine habitat, provide for protection and upward growth of juvenile oysters and allow the oysters to form bridges between the columnar extrusions within the tile, from tile to tile, and from the tile to a sandy or silty bottom of a body of water to form a contiguous reef;
- and wherein the base has one opposite face that is irregularly shaped into ridges and grooves for attachment of the tile to a sandy or silty bottom of a body of water.
