The overall objective of this project was to determine the suitability of waste concrete from road projects as bottom conditioning material for on bottom oyster aquaculture in the Chesapeake Bay. The objectives for Phase 2 are to: (1) evaluate the potential introduction of organisms attracted to the reclaimed concrete aggregate (RCA) pile that may be potential predators of oyster spat; and (2) determine potential impacts or disruptions in the use of traditional harvesting gear on aquaculture areas conditioned with RCA. As appropriate, recommendations of thickness of native shell overburden will be provided to mitigate any identified impacts.
