Trestles

The traditional trestle can be adapted to receive SEAPA baskets (usually by 10) attached with clips. They are set at fixed height depending on the height of your lease and placed on the seabed in an intertidal range tied at each leg with steel bars. 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 and prevent issues of meshing and doubling.
Adapted for exposed areas
Increase efficiency and speed
Enhance shell shape and volume
Better stock management

Long Lines

Developed in South Australia, the Adjustable Long Line System gives the farmer the ability to have greater control over their stock. This is achieved by raising and lowering the line to different heights set on the posts during different seasons, environmental conditions, and stage in oysters’ growth.
Farmers will lower the line if they need the oysters to grow at a faster rate, or for preparation of a storm event, and they will raise the oysters to control biofouling increasing the time the oysters are out of the water. A raised line also is set for oysters conditioning, as it has less time in the water and greater time in the wave impact zone which will rumble the oysters in the baskets keeping them clean and stunting shell growth.
Ability to raise and lower the stock
Can be protected during storm episodes
Easy cleaning process of the line
Suits sandy and muddy seabed areas

Subtidal systems

There are multiple variations of floating systems used around the world. One option is to stack the baskets on top of each other using the Premium End Caps.
The modules can then be tied down utilising metal frames, ropes in calm areas, or other materials to reduce movement of the baskets. The baskets can also be deployed individually by laddering on a purpose made frame or deploying with clips on a floating longlines.
Secure infrastructure on open waters
Leverage water column depth for stock holding
Promotes rapid growth
Transfer between subtidal and intertidal systems
