Joe Reiger's Oyster Restoration Workshop Presentation
The document discusses alternative substrates and designs for oyster restoration. It provides information on different material options for oyster reef construction including oyster shell, whelk shell, crushed concrete, and granite. Costs for each material are given. Different reef designs are presented including straight face, diamond face, and zig zag configurations. Examples of completed oyster restoration projects using various structures like oyster castles and oyster bergs are shown. Open questions are provided on considering additional substrate and shell sources, more cost effective and higher quality reef designs, and other potential oyster structures.

- 21. Questions? What othertypes of alternative substrate should we be considering? What types of other shell sources or types should we be looking into? Are there better designs for reefs which make them higher quality habitats and also more cost effective? What other types of oyster structures are out there and how can they be used in reef design?
