By obtaining local data from seven states (North Carolina to Louisiana), site-specific guidance was developed to optimize production of high-quality oysters in the region. Water temperatures measured from September 2017 through June 2018 at the Dog Island Aquaculture Use Zone off Cedar Key, Florida. At that time, oysters measured 52 mm in shell height (SH), 39 mm in shell length (SL), and 16 mm in shell width (SW). Since Florida was one of the study sites, a comparison of floating cages with floating bags, which are used by many oyster growers in the state, was also evaluated. We like the 1/2-inch because it suits the size of our young oysters when they go into the cage. Or, you can leave the bottom tier empty, but I hate to do that because its leaving real estate unused.

Shell height, shell length and survival results for oysters cultured in floating gear. Pictures were taken to document appearance of external and internal shells as well as meats. We have a sandy/cobble bottom (sedimentary stone,) so the pointed leg (riser, v-mesh) is perfect. Condition index is a weight ratio that describes meat yield, in terms of dry meat weight, total wet weight, and dry shell weight (equation below). The long line floating oyster mesh bag taps into the nutrient and oxygen rich surface water which enables the oyster to grow much faster than traditional inter tidal oyster farming. Figure 5. We raise our oysters in an off-bottom cage placed just above the water bottom. Percent biofouling on oysters and culture bags in floating cages evaluating a) flipping regimes, b) antifouling bag coating versus none, and c) bag position.

Jaillet said he has to flip 1,300 cages, each weighing over 75 pounds, eight times a year. Projects. Their cage-turning efforts discourage mussels, barnacles and algae build-up, which lets water circulate better and more food reach the oysters. There, they'd be hosed down and exposed to sunlight to rid them of fouling organisms that limit the oysters' growth. As the FlipFarm system supplier operating out of Yarmouth, Maine, we're excited to share information and demonstrate the system's effectiveness to fellow oyster farmers. Oysters in FC-T had higher total weights (116 g) compared to FG-B (110 g) and FB (104 g), but differences were attributed to the amount of fouling on the shells. We believe that the client comes first - which means exceptional products, fair pricing and knowledgeable service. Figure 7. Sustainable aquaculture industries, such as oyster aquaculture, are critically important to support protein production for the global human population (FAO, 2020), and are an increasingly important economic driver for coastal states of the U.S. (USDA, 2019). Made from 95% re-compounded recycled plastic. Oysters in cages flipped weekly, biweekly and triweekly had similar survival, shell heights, shell lengths, shell widths, total wet weights, and condition index regardless of bag position (Figures 3c and 4c). The flipping allows algae, barnacles, and other "biofouling" organisms that grow on the part of the bag beneath the water's surface to be exposed to air and light, so they can dry and chip off. These aquaculture producers are also committed stewards of the environment, managing their farms with sustainability in mind.
