50MD Monofilament Aquaculture Farming Net — High Quality Double Knot, Best Selling

Cage farming runs on predictable numbers — how deep the panel hangs, how open the mesh stays, how long the netting survives saltwater — and a net that drifts from spec costs money in escaped fish and rebuilt pens. This 50 MD nylon monofilament farming net is built to a standard aquaculture specification: 50 meshes down of depth, double-knotted to stop fraying at the intersections, with a 3–5 year service life in saltwater farming.

Spec'd for Farming, Not Fishing

• 50 MD is a repeatable depth spec — "mesh down" depth means you know exactly how much netting covers a pen circumference, so quoting, ordering and replacing panels is predictable instead of guesswork
• Double knot against fray — in a cage every fish touch and wave action works the intersections; double knots hold the yarn where single knots loosen and fray over time
• 20–60 mm mesh, typical for farming — sized so stock stays in while water exchange keeps flowing; mesh too fine chokes the cage of current, mesh too coarse loses fish
• Black or green — dark filaments are less visible to farmed fish, which reduces panic and fin damage; dark netting also holds up longer under UV
• Nylon monofilament — the wet-strength and abrasion balance suits panels that stay submerged year-round

Mesh Size by Stock Stage

• 20–30 mm — fry and fingerling rearing where escape is the main risk
• 30–50 mm — grow-out stages, the most common farming range
• 50–60 mm+ — adult stock, where maximizing water exchange takes priority

When ordering, give us cage diameter and depth rather than a guessed panel size — we translate those into mesh counts and panel layout. Plan a spare panel per pen size; fouling gradually reduces water exchange, and swapping a panel beats patching it in season.
