Stingray anchors are ideal for suspended oyster farming due to their characteristics as follows,
High holding power in soft sediments (mud/sand common in oyster habitats)
Low seabed disturbance (protects benthic ecosystems)
Lightweight design (easy deployment without heavy machinery)
Self-burying capability (improves grip over time under tension)
Anchor Spacing:
For single longlines: Anchors placed 50-100m apart (depending on tidal currents).
For grid systems: 10x10m grid with anchors at corners and midpoints.
Depth Range: Optimal for 5-30m depths (typical oyster farming zones).
| Component | Specifications | Purpose |
|---|---|---|
| Stingray Anchor | Galvanized steel, 50-200kg (size-dependent) | Seabed fixation |
| PP/HMPE Hybrid Rope | Ø12-16mm, UV-resistant, buoyant | Connects anchor to surface floats |
| Adjustable Floats | HDPE with depth markers (3-15m adjustability) | Suspends oyster cages at optimal depth |
| Swivel Connectors | 316L stainless steel, 360° rotation | Prevents line twisting |
3. Longline Setup
Connect anchor to mainline via swivel.
Attach floats at 5-10m intervals.
Suspend oyster cages (e.g., lantern nets or trays) on dropper lines.
Tension system to 20-30% SWL for initial settling.
