Abstract:

The overall objective of this study was to determine the suitability of recycled concrete

aggregate (RCA) from road projects as bottom conditioning material for on-bottom oyster

aquaculture in the Chesapeake Bay. During this Phase of the study, the research team

placed RCA on test plots in the Chesapeake Bay to evaluate the impact on the benthic

community. Miniature oyster reefs were also built to determine potential impacts or

disruptions of RCA on the use of traditional harvesting gear. The results of this project

showed that 1.) There was no significant difference between substrate type (RCA, oyster

shell) on benthic community structure, oyster recruitment, and the abundance and size

distribution of key faunal species, demonstrating that RCA, as an alternative material, was

generally similar to natural oyster shell with regard to ecosystem services provided, and

2.) RCA makes a suitable substrate for supporting oysters for aquaculture operations but

would require a veneer of old shell to be placed on top so as not to introduce additional

weight to the catch when using shaft tongs
