Common Mesh Sizes for Oyster Farming

Other Factors Influencing Mesh Choice
Material: Meshes are usually made from HDPE (high-density polyethylene), plastic-coated wire, or nylon.
Shape: Mesh can be square, hexagonal, or diamond, depending on design.
Rigidity: Some meshes are flexible (for spat bags), others are rigid (for grow-out baskets).
Biofouling management: Larger mesh sizes reduce fouling but may lose smaller oysters if used too early.
Summary Tips
Start with small mesh (1/8"–1/4") for oyster seed.
Gradually increase mesh size as oysters grow.
Match mesh size to local water flow conditions and biofouling risk.
