A technical deep-dive into how a 400HP vessel coordinates 4 synchronous nets to cover 12,000㎡, achieving a **5.2-ton catch** in a single tide.
**Large Yellow Croaker (Larimichthys crocea)** is notoriously sensitive to sound and light. Traditional trawling creates vibrations that scatter the schools long before the net arrives.
To capture them effectively without damage, the operation requires **absolute silence** and **massive coverage** to entrap the dispersed school before they panic.
Our system links four independent 30m-diameter Cover Nets into a single strategic matrix.
Yellow Croakers have excellent vision. We utilize a proprietary **Matte-Black Coating** on the 280D PE twine.
Sustainability is key to long-term profits.
How does a single 400HP vessel control 4 nets simultaneously? Through **Beidou Grid Synchronization**.
The vessel uses hydraulic thrusters to position 4 nets 30m apart. Beidou positioning ensures error < 0.5m.
Lights dim. All 4 nets release their self-adaptive sinkers simultaneously. The "Stealth Net" drops instantly, creating a 12,000㎡ enclosure.
Float lines inflate instantly. The nets rise at **200% speed**, trapping the school before they can react.

"The synergy is mesmerizing. When all four nets sink synchronously, it creates a 'Golden Whirlpool' on the surface! The 0.32mm PE net withstands Force 8 winds, yet is invisible to the fish. We are no longer just fishing; we are harvesting gold."
Customizable for 20-35m vessels. Perfect for High-Value Species like Grouper and Sea Bream.
