Fixed Systems

Fixed systems involve the construction of metal frames, wooden racks, longlines set at a fixed height or other structures which are placed on the seabed in an intertidal range. Baskets are set through this installation allowing the oysters to open and feed when the tide is in. When the tide goes out, the oysters are exposed to the air which helps to manage biofouling and hardens the shell. Through the tide transition, the baskets enter the wave impact zone which promotes oyster rumbling. Floats can be attached to the baskets to help increase basket movement, in turn promoting the oysters to rumble in the baskets.
