Over the last decade, oyster aquaculture has expanded rapidly in Maine. New and existing producers are interested in methods to improve shell quality to compete in the half-shell market. A common technique to improve shell shape is intertidal gear, which utilizes energy from the tide to tumble oysters in their bags to break the outer shell rim. The constantly chipping shell results in a deeper cup shape, however, often at the cost of oyster growth (4). In this study, we are investigating the effects of four different intertidal gear types as well as stocking density on time to market, shell shape, and condition index at two different sites along the Damariscotta River. The results of this study will help determine (1) if intertidal farming is profitable and (2) the optimal gear type and husbandry practices to best suit consumer demand.
