Consequently, weekly flipping of floating cages is recommended to minimize biofouling on gear and oysters in Florida growing conditions. This will expose the cage and all its content to the sun and wind and within a short period of time (no more than 48 hours) all the fouling and secondary spats should be eliminated. To quantify biofouling in this study, oysters were weighed before and after removal of all fouling organisms from the shells, then wet meat weights were subtracted from total weights to determine percentage of fouling weight (see equation below). Our oysters are about 1 1/2 inches when they go into the open bay, so a half-inch square size mesh makes sense. The bottom of the first and second trays serve as lids for the others in the stack. It also. Faster is good and I am open to suggestions. Highlighting the delicious [], Hand crafted oysters with the OysterGro system.

We tried a two-tier cage before going with the three-tier system were still using. We ghost-line our cages together underwater. Frost believes solving the flipping problem could open up big market opportunities for the flipper and for the OysterGro floating cage system. Six Bag Oyster Cage System The largest size of floating systems on the market, the six bag configuration houses an impressive amount of juvenile oysters although competition for food is high. The predominant fouling organism was barnacles, followed by naturally occurring (wild) oyster spat (Figure 7). 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.
