The system is adaptable to diverse growing environments and is now used by more than 70 farmers in 12 countries worldwide, said the company. Our oyster farm needed three key improvements - 1. to reduce the labor needed for de-fouling, 2. to be able to harvest efficiently and 3. to scale in volume to improve the economic proposition of oyster farming. However, initial field observations found H. dianthus particularly problematic at Eel Lake, as desiccation alone did not remove biofouling from oysters and cages. Biofouling accumulation on the gear was quantified by weighing Vexar bags immediately after harvest and subtracting the weight from the corresponding pre-deployment bag weight expressed as a percentage of the bag weight at harvest (see equation below).

The bag position was determined when the cage was in the drying position during aerial exposure (Figure 1). In the suspended oyster aquaculture industry, floating bags or OysterGro cages are flipped periodically to expose biofouling organisms to air which results in desiccation (Mallet et al. 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).
