SEAPA Pty Ltd. products

All 15 litre baskets are available in the full range of mesh sizes and end cap designs. The baskets are designed to provide secure containment and efficient stock management. The 15 L basket is the original, highly productive system for longline farming, however, with appropriate end cap and attachment clip system selection, the baskets can be adapted to suit a range of alternative farming systems and methods. All baskets stack neatly for efficient use of space whether it be on your boat transferring baskets, or in the yard for storage. Automation is also an option.

Seapa Spat socks are an innovative mesh sleeve designed to fit inside our 15L baskets and hold oyster spat down to 2mm in size. Available in 1mm and 1.6mm mesh sizes and constructed from high quality, UV stabilised Polyester materials with reinforced seams to ensure stock is safe and secure. For best results, SEAPA recommends installing these into the 20mm mesh basket to allow for optimal water flow.

Seapa 25 litre baskets are designed for elevated stocking densities and wide versatility in farming methodologies. Available in 12mm, and 20mm mesh sizes, the range targets conditioning oysters for market. The larger end cap circumference allows for bigger, flatter growing area. The 25L basket securely holds stock with easy access through the hinged door at one end. The unique design also enables conveyor automation, including automated door opening and closing.

The 15L and 25L baskets are available with either a Streamline or Premium end cap*.

Developed in South Australia, The Adjustable Longline 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 oyster 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.

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.
