Aquaculture Equipment Manufacturer & Supplier
Traps, baskets, floats, cages and netting for shellfish and finfish farms — corrosion-built for continuous saltwater immersion, OEM & wholesale from Weihai, China
Aquaculture is the most demanding service environment we build for. Equipment sits in saltwater continuously — not the wet-dry cycling a day boat sees — so corrosion, biofouling, and material fatigue work on it around the clock. Gear that is merely "marine-grade" on paper fails fast here; what survives is built and finished for permanent immersion from the start.
Everwin supplies the containment, floatation, and rigging that shellfish and finfish operations rely on, produced on the same wire-forming, foam, and net-weaving lines as our commercial fishing range — and sized or specified to your species and site.
Built for permanent immersion
Lead-free, cadmium-free marine-grade PVC vinyl over galvanized wire, closed-cell foams, and stainless fixings selected for continuous saltwater service — not occasional exposure.
Low-impact & compliant
Biodegradable escape panels, compliant mesh openings, and high-visibility marking help your operation meet environmental rules and avoid ghost-fishing losses.
Sized to your grow-out
Custom mesh openings, basket and cage dimensions, and buoyancy ratings produced to your species and site — from trial quantities to full farm rollouts.
Equipment for aquaculture operations
A working farm draws from across our fishing range — containment, floatation, and the rigging that ties it together.
Containment: baskets, cages and traps
Grow-out and harvest containment is the core of a farm order. Vinyl-coated wire baskets and cages resist the corrosion and abrasion of permanent immersion while protecting stock from damage, and custom mesh openings let you match containment to the size of the animal at each stage. For wild-stock supplementation, the same trap and basket lines used by commercial fleets carry over directly.
Floatation and mooring marking
Closed-cell EVA and PVC foam floats stay buoyant even when the outer skin is nicked, so a damaged float doesn't sink your line. High-visibility, UV-stable colors keep gear locatable and legal across a site. For the ground tackle that holds longlines, cages, and raft systems in place, our marine hardware range supplies the anchors, chain, and connectors — see the mooring & rigging application.
- Unsinkable closed-cell foam — buoyant even if punctured
- UV-stable high-visibility colors for site marking
- Custom buoyancy ratings for longline and raft systems
Common questions
Are your coatings safe for food-grade aquaculture use?
We specify lead-free, cadmium-free marine-grade PVC vinyl on coated wire products, suitable for shellfish and finfish containment. Tell us your jurisdiction's requirements and we will match the coating spec.
Can you produce custom mesh openings and cage sizes for our species?
Yes. Mesh opening, basket and cage dimensions, and buoyancy ratings are all customizable to your species and grow-out stage. Custom sizing runs on the same lines as our standard catalog, typically from 500 units.
What is the minimum order, and can we start with a trial?
Standard items ship from stock; custom-specified gear typically starts around 500 units, though trial quantities for site testing can often be arranged. Contact us with your spec and we will confirm MOQ and lead time.
