A net pen capture device and method of use thereof

Abstract

The application discloses a net cage catching device and a using method thereof. The device comprises a floating platform, a net, a net skirt, a supporting component and a bottom net component. The supporting component is connected between the net and the net skirt and has an even number of supporting rods. The rod ends of the supporting rods are sequentially and movably connected to form a closed loop. Adjacent supporting rods can be bent upward or downward at the connection and the bending angle is limited. The connection is subjected to upward and downward tension. The supporting rods are unfolded from the bent gathering state to the same horizontal plane to form a polygonal structure. The bottom net component is connected below the net skirt and is driven to move up and down. The application not only realizes the rapid unfolding of the net and the net skirt in water, has a small structure space, but also realizes the rapid closing of the fish inlet space. In the case of ensuring the large fish inlet diameter / channel, the fish inlet effect and the catching efficiency are effectively improved, the fish escape is avoided, the fish loss rate is reduced, the fish is gradually gathered, and the unified collection operation is facilitated.
