Weekly and triweekly flipped cages produced oysters with similar wet and dry meat weights regardless of top or bottom position of the bags; however, oysters grown in bags placed in the top position of cages flipped biweekly had higher wet (21 g) and dry meat weights (2.4 g) compared to those in bottom position bags (15 g, 2.0 g) (Figure 4c). Made from 95% re-compounded recycled plastic. Likewise, oysters in these bags had higher wet and dry meat weeks as they tended to be in the water longer. Similarly, cup ratios were higher in weekly flipped cages (0.38) compared to biweekly (0.37) and triweekly (0.36) flipped cages. 14G Double Stack Seed Cage.

Our products are flexible and adaptable and are used to provide innovative solutions on farming systems, in particular, those focusing on single seed oysters. Oyster tissue samples will be collected at three different farms for analysis of Vibrio spp. levels. Shell height, shell length and survival results for oysters cultured in floating gear. This is also reflected in condition index differences obtained for oysters in the three flipping regimes. No differences in biofouling were found on bags placed in the bottom position of cages regardless of flipping regime (65-69%). Easy to use and lightweight enough for a single person to manage without additional equipment the two bag OysterGro cages are an excellent choice for a small oyster aquaculture farm operation. Exposing oysters to the air (and elevated temperatures) can increase human health risks associated with consuming live, raw seafood due to increases in naturally occurring pathogenic Vibrio bacteria, Vibrio vulnificus and Vibrio parahaemolyticus (Su & Liu, 2007).

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). We tried a two-tier cage before going with the three-tier system were still using. That could cost from $60,000 to $200,000 depending on a number of variables. Figure 5.

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). Growers have traditionally flipped cages manually some as heavy as 200 to 300 pounds when the oysters are near harvest. The finalists were selected from a pool of 39 applicants from 24 countries. Fisheries & Aquaculture Ministers Conference in Halifax Nova Scotia Day 2, Our OysterGro Dealers are flying the flag at Oyster South 4, Community initiative drives sustainable aquaculture forward, Oyster Farming in the Southern United States Using the OysterGro System.
