Floating Bag System

1000 Small oyster seed are placed in a ¼” mesh floating bag. They will stay in this bag until they are approximately 1 inch in size.

Once the oysters are 1 inch in size they are placed in a ¾’ mesh bag at a density of 500 oysters per bag. When the oysters reach about 2 inches in size, the density is reduced to 250 oysters per bag. As they grow to 3 inches (market size) the density is again reduced to 100 oysters per bag. When the final cull is done, the density is reduced once more to 52 oysters per bag for harvesting for market.

The oysters are stocked volumetrically. A count of a few hundred oysters is preformed, and then their volume is determined. We can therefore, calculate how many mL or L of oysters will be needed for the appropriate density.

Once the bags are stocked, and cable tied closed, they are brought to the shallow site.

Each bag is then evenly spaced and secured to the longlines with the duck hooks.

The oysters will stay floating in these bags for 2-3 years until they reach harvest size, and they are then sold to market.

Every 2 weeks the bags are flipped over to allow any fowling to be baked off by the sun. This allows the bag to stay clean and have lots of water flowing through them bringing nutrients to the oysters for growth.
