Best Wire Mesh for Fish Ponds and Aquaculture

PVC Coated Hexagonal Wire Mesh is the recommended product for fish ponds and aquaculture in West Bengal. Standard GI mesh corrodes rapidly in constant water contact - typical lifespan is 1-2 years. PVC coated mesh lasts 5-8 years in pond environments. Use 1" aperture for fish cages and pond boundary fencing. Use 1/2" aperture for prawn and shrimp pond screening where smaller openings are needed to prevent escape. For brackish water environments (coastal areas), use SS316 woven wire mesh - it is significantly more expensive but lasts 15+ years. Most inland fish farmers in Bengal use PVC coated GI hex mesh as the practical cost-effective choice.
