For the next 2-3 years we flip oyster cages over and back regularly to burn off the seaweed and barnacles that attach to the bags and cages. Although statistical differences were found between oysters in coated and uncoated bags placed in cages flipped weekly, growers most likely would not find the differences in values for growth, weight, and condition index of commercial significance (Figures 3b and 4b). They house oyster grow-out mesh bags and keep them secure from floating away or touching the bottom. Farmers must strike a balance between maximizing production efficiency while providing a safe, sustainable product, and have requested an in-depth study on best management practices for air-drying and resubmergence.
