Over the last four months Jaillet developed a barge equipped with a robotic device that flips an oyster cage from side to side, preventing algae build-up. Flipping exposes all sides of the cage to the sun and kills the parasites that have attached themselves to it. You must be safe. Although oysters in all gear treatments exceeded the preferred fan and cup rations, oysters in FC had significantly higher fan ratios (T, 0.77; B, 0.79) compared to oysters in FB (0.71). Placement of bags in each cage (three on the top level and three on the bottom level) was also followed throughout the growout period (Table 1). Biweekly and triweekly flipped cages produced oysters with higher shell heights (92 mm) than those in weekly flipped cages (85 mm). Although there was a lower percent fouling (61-62%) observed on coated bags in the biweekly and triweekly flipped cages versus uncoated bags (68-69%), the differences most likely would not justify the coating costs. We also work from our boat, so having a robust mesh, it makes it easier for us to winch cages inside our boat. Figure 3. Oyster Farming in Maine is messy, difficult and sometimes dangerous work, Attracting innovative, newtalent into oyster farming is challenging, Scaling an oyster farm to a volume that supports a family or small business profile requires about 1 farmer per 250,000 market sizedoysters, The work is injury prone and the type of labor is even more challenging in the winter. Chafing can be a problem, especially on the bridle and leader lines. The position of the bags in the cages had a significant effect on oyster meat weights (a sensitive measure of growth) and biofouling. In addition to field data collection, an analysis of current policies and decision-making practices will be conducted to evaluate how the data may inform regulations in an efficient manner to foster a sustainable oyster farming industry that works in harmony with environmental, economic, and sociopolitical parameters. SARE Outreach operates under cooperative agreements with the University of Maryland to develop and disseminate information about sustainable agriculture. An apparatus for flipping a floating oyster cage comprising: a fixed ring; a rotatable ring rotatable concentric with the fixed ring; a means of rotating the rotatable ring relative to and concentric with the fixed ring; and a plurality of supports fixed on an interior surface of the rotatable ring such that one support extends at a first angle to the interior surface . Percent biofouling on oysters and culture bags in floating cages evaluating a) flipping regimes, b) antifouling bag coating versus none, and c) bag position.
