Figure 7. In the biweekly (127 grams, g) and triweekly (122 g) flipped cages, oysters had higher total weights compared to those in weekly flipped cages (111 g); whereas wet (17-18 g) and dry (1.9-2.4 g) meat weights were similar for oysters in all cages regardless of flipping regime (Figure 4a). However, significant differences detected in biofouling have management implications for a grower as floating bags (FB) and bags placed on the bottom level of floating cages (FC-B) had the least amount of fouling compared to bags placed on the top level of floating cages (FB-T).

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. Results: Survival, Growth, Condition Index. Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture or SARE.

This is the same woman that gave me an oxyacetylene blow torch on my 12th birthday. No differences among treatments were found in oysters grown in bottom position bags for shell growth, weights, and condition index. The accumulation of biofouling on oysters and gear for each treatment was quantified. My properly installed cages have withstood two cat 5 hurricanes and several lesser storms without loss of equipment.

Panelists: When filled with oysters, a cage is not the easiest thing to get on board your deck. 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). The oyster cage is a flexible way to raise your oysters, either floating on or at the bottom of water.
