Marine Fishing Barrier Hook Net

Marine Fishing Specialized Barrier Chain Link Net - Anti-Escape / Seawater Corrosion Resistant / High Catch Rate - Offshore Aquaculture / Seine Fishing / Cage Isolation - Metal Chain Link Net

II. Product Overview:

This marine fishing barrier chain link net is specifically designed for offshore seine fishing, seawater aquaculture escape prevention, and fishery partition isolation. Woven from highly corrosion-resistant metal materials, it features resistance to seawater erosion, precise mesh to prevent small fish escape, high strength, and drag resistance. It can adapt to complex marine environments such as tides, waves, and salt spray, effectively improving fishing efficiency and reducing aquaculture losses. It is an efficient auxiliary tool for offshore fisheries.

III. Core Advantages: Customized Selling Points for Marine Fishing Scenarios

Combining marine environmental factors (high salt, high humidity, wave impact) and fishing requirements (escape prevention, fishing efficiency, reusability), highlighting differences from ordinary fishing nets:

1. Superior Seawater Corrosion Resistance, Lifespan Far Exceeds Ordinary Fishing Nets

• Material and Craftsmanship: Made of 316 stainless steel wire (or high-zinc layer galvanized steel wire), with nickel content ≥10% (316 material), salt spray resistance is over 5 times that of ordinary carbon steel. Wire diameter ranges from 2.0-4.0mm (customizable), capable of resisting chloride ion erosion in seawater (in environments with 3.5% salinity).
• Surface Treatment: 316 stainless steel wire inherently resists corrosion without additional coating; galvanized steel wire undergoes "hot-dip galvanizing + passivation" process, with zinc layer thickness ≥120μm, salt spray test resistance ≥1000 hours. Lifespan in seawater immersion environments can reach 5-8 years (compared to 1-2 years for ordinary fishing nets), significantly reducing repeated procurement costs.

2. Precisely Designed Mesh, Balancing Fishing Efficiency and Escape Prevention

• Mesh Specifications and Applicable Scenarios:
  • Small fry/shrimp seining: Mesh sizes 1cm×1cm, 1.5cm×1.5cm, precisely blocking fry over 3cm in length to prevent escape, suitable for hatcheries or precision aquaculture.
  • Adult fish seine fishing: Mesh sizes 3cm×3cm, 5cm×5cm, allowing water flow and plankton passage without affecting fish growth environment, while preventing adult fish (over 10cm in length) from escaping, improving seining success rate.
  • Fishery partition isolation: Mesh sizes 6cm×6cm, 8cm×8cm, used to divide different fish farming areas (e.g., separating adults from juveniles) or isolating diseased fish to avoid cross-infection.
• Weaving Process: Utilizes "double-strand chain link weaving" with uniform mesh size error ≤0.5cm, smooth net surface without burrs to avoid scaling fish (especially high-value species like sea bass and yellow croaker). The net body has good flexibility, resisting tearing under wave impact.

3. High Strength Impact Resistance, Adapts to Marine Waves and Dragging

• Tensile and Impact Resistance: Breaking strength ≥600MPa (316 stainless steel wire), can withstand boat dragging (speed ≤5km/h) and wave impact (wind force ≤8 level). The net body can elastically deform (elongation ≥20%) under force and return to original shape after tension release, resisting breakage or deformation.
• Edge Reinforcement: Net edges feature "stainless steel wire rope binding" with rope diameter 6-8mm, connected to the net body via "crimping + welding" dual fixation, paired with specialized metal hooks (rust-proof treated) for easy connection to buoys and anchor piles, ensuring stability without sinking or shifting during tidal changes.

4. Flexible Adaptation, Covers Multiple Marine Fishing Scenarios

• Applicable Scenarios:
  • Offshore seine fishing: Serves as a "mobile barrier," forming enclosed areas through multi-panel拼接 to seine schooling fish (e.g., pomfret, ribbonfish). The net has good light permeability (transmittance over 60%), not affecting fish swimming habits, improving seining efficiency.
  • Seawater aquaculture escape prevention: Used for outer reinforcement of cages or pond boundaries, replacing traditional nylon nets to prevent carnivorous fish (e.g., grouper) from breaking through and escaping, while blocking entry of foreign杂鱼.
  • Fishery partition management: Divides large farming areas into multiple sub-zones for batch fishing or species isolation. The net can be quickly disassembled and reassembled, allowing flexible adjustment of zone sizes.
