The terms perforated and mesh are often used when describing materials like baskets, bags, or screens — especially in aquaculture like oyster farming. Here's the key difference:
Perforated vs. Mesh
| Feature | Perforated | Mesh |
| Definition | Solid material (usually plastic or metal) with uniform holes punched into it | Woven or knitted structure made of fibers or wires creating interconnected openings |
| Hole Shape | Round or square, cleanly cut | Can be square, hexagonal, or irregular — often flexible |
| Material Structure | Rigid sheet with holes | Flexible net-like or fabric-like material |
| Strength | More rigid and durable | More flexible, but may tear or deform under strain |
| Water Flow | Good, depending on hole size and spacing | Excellent — high permeability to water and debris |
| Typical Use | Oyster grow-out baskets, seed trays, bottom cages | Nursery bags, predator nets, floating bags |
| Cleaning | Easier to clean (solid surface) | Can trap more debris or biofouling in small fibers |
In Oyster Farming:
Mesh bags are often used in early stages (nursery), allowing high water flow and holding very small oysters.
Perforated trays or baskets are used in grow-out stages where strength and protection are needed, especially in wave-prone areas.
Summary:
Perforated = solid with holes
Mesh = woven or net-like
