Abstract
The invention discloses a double-beam double-net plate euphaussid shrimp fishing boat comprising a boat body, a surface layer euphausiid shrimp fishing device and a middle layer euphausiid shrimp fishing device. Seawater surface layer euphausiid shrimps can be continuously fished via the fishing boat and euphausiid shrimps in the seawater middle layer can be also continuously fished; and two the fishing methods can be switched. The surface layer euphausiid shrimps fishing device comprises euphausiid shrimps nets, beams, dragging nets, chord external supporting racks and euphausiid shrimps pumping absorbing devices. The middle layer euphausiid shrimps fishing device is formed by an euphausiid shrimps net, hand nets, net plates, dragging nets and an euphausiid shrimps pumping absorbing device. According to the distribution of the euphausiid shrimps groups in the water layers, two fishing methods can be switched as needed, so boat fishing efficiency and adaptability to work water area can be improved; by the use of pumping absorbing devices, nets can be prevented from being frequently lifted up, so fishing efficiency can be enhanced and labor intensity can be reduced.
