Traditional Intertidal

Traditional Intertidal farming systems include:

Rack and Rail which involves the construction of metal frames, wooden racks, or other structures which are placed on the seabed in an intertidal range. Baskets are secured to the racks allowing the oysters to open and feed when the tide is in as they are in the water. When the tide goes out, the oysters are exposed to the air which helps to harden the shell.
French Trellis which are generally metal frames.

The SEAPA Premium baskets are extremely versatile and can be configured to take a wooden stake to sit across fixed rack systems.  These stakes may be placed through the end caps for baskets to sit across (perpendicular to) racks or using an accessory attachment to sit along (parallel with) the rack.  The added benefit of this method is that the baskets can be inverted on the rack to change the working height either above or below the rails.
Longer Premium baskets (25, 34 and 45L Range) often require no wooden stakes when used on traditional French tables as they will comfortably sit across them.  If finer mesh sizes are required, the tables can be modified to take the clips and facilitate swinging by welding lugs at intervals on both sides of the metal table.

Seapa recommends the following Seapa products for this farming system:
