There are four main types of oyster farming:

1. Traditional Bed or Bottom Culture

Oysters are grown on the grounds of intertidal regions(the area that is above water at low tide and under water at high tide), feeding on the plankton available in the incoming tide. These areas are usually gravel or hard packed sand beaches.

2. Rack and Bag Culture

Oysters are cultivated in plastic net bags(see our new oyster bag system above) supported above the ground on steel racks so that water can flow completely around the oysters allowing them to feed faster and be protected from crabs and other predators. This method also makes it possible to grow oysters in areas which might otherwise be too muddy to grow them directly on the intertidal grounds.

3. Suspended Culture

This method may vary between suspended tray culture or lantern net culture. The purpose of this method is to allow for growing oysters in deeper, sub tidal waters. The oysters are placed in trays or nets which are suspended from floats or sub-tidal longlines so that they hang below the surface of the water 24 hours per day allowing for the oysters to grow very fast.

4. Intertidal Longline Culture

Another suspension method where adult oyster shells with baby oysters set on them, are then inserted into the strands of a rope. The shells are spaced out every foot or two along a 300-600 foot rope, and that rope is then stretched along the ground in the intertidal region at low tide, and the rope is then supported about a foot above the ground with pegs. The end result is that the entire length of rope and shell is suspended above the natural bed allowing for the oysters to grow faster than they would settled down into the mud or sand.
