I. The "Light-Responsive" PE Netting System

Traditional nets cast shadows that spook sensitive pelagic fish. Our solution utilizes Fluorescent Green 550D PE Multifilament that works in harmony with underwater lights, becoming virtually invisible to the fish while maintaining extreme structural integrity.

▶ Strategic Mesh Configuration

  • 1
    Wing Section (35mm Medium Mesh):
    Optimized to balance tensile strength with 82% light transmission, ensuring the "wall of light" remains unbroken.
  • 2
    Body Section (25mm High-Strength):
    Reinforced zone designed to absorb the chaotic kinetic energy of a 200-ton fish school without bursting.
  • 3
    Cod End (10mm Micro Mesh):
    Precision Retention: Prevents commercial-grade mackerel escape while allowing undersized larvae to pass through (>99% survival rate for juveniles), meeting ecological standards.

II. The Thousand-Light Matrix (The Heart)

The success of the Zhe Xiang Yu Guang 618 (45m Catamaran) lies in its Spectral Synchronization.

System Component Specification
Light Source 1,000 x LED Array
Wavelength 450-550nm (Blue-Green)
Intensity 2 Million Lumens
Coverage 1.2 Nautical Miles Radius

💡 Why 450-550nm?

This specific "Blue-Green" spectrum perfectly matches the biological phototaxis (light sensitivity) of Chub Mackerel. When combined with our Fluorescent Green Netting, it creates an irresistible "Golden Trap," gathering fish from over a mile away.

"When the thousand LED lights turn on, the sea surface boils like molten gold! The synergy is incredible: the 0.50mm PE net holds the 200-ton shockwave without a single tear, yet the 10mm cod end lets the juveniles escape. One night's catch with this system equals a trawler's weekly output."
