We evaluate how well the gear works - in the water and on deck. An effective biofouling control strategy for floating cages would be to rotate bags from top to bottom as culling and sorting activities take place to reduce the amount of fouling, though this was not examined in this study. This study will undertake a whole-systems approach to collect field data, understand inter-agency communications, and develop policy recommendations to maximize agricultural sustainability and efficiency for the coastal shellfish aquaculture industry. 1 Inch Cage - 3'x4'.

It also gives us a signature. Appearance of oyster meats harvested from floating culture gear. The use of an antifouling coating on bags had no effect on biofouling in cages flipped weekly as values were similar (54-57%). Not only am I doing the operation that needs to be done, but Im also accomplishing all of my thoughts and all of my stuff that I have to do. We tried a two-tier cage before going with the three-tier system were still using. 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). Closed Captioning and Described Video is available for many CBC shows offered on CBC Gem. Control practices in this study were effective in reducing biofouling as most of the culture period was conducted during the cooler months but may not be as effective during a summer growout period when biofouling is at its peak. at different pre-handling, post handling, and post-resubmergence time points (i.e., 5, 7, and 14 days after resubmergence), with trials repeated on two occasions during Vibrio control months (i.e., May-September).

Results: Oyster Shell Shape and Meat Appearance. However, oysters grown in FC-T bags had slightly higher shell heights (87 mm) compared to oysters in FB (84 mm) and FC-B (84 mm). Flipping provides added benefits in shell strength and shape helping to form the deep cup where the oyster can grow and access the natural food sources provided by the cold Atlantic waters. The OysterGro system has been a game changer for us; other gear simply did not perform as well as this system, especially when hurricanes so frequently threaten our farm. Unassembled Kits - Hardware not included. These data were statistically analyzed to determine the effects of cage flipping, bag antifouling coating, and bag position on oyster growth and survival; results were considered significant when probability values (p) were less than 0.05.
