The invention discloses a fishing boat trawl internal anti-extrusion fishing method applied to marine fishery engineering, and belongs to the technical field of marine engineering methods. A traction structure, a fishing structure, an inner cavity partitioning structure and a spiral driving structure are included; A hull structure is in transmission connection with the fishing structure through the traction structure, so that the fishing structure can synchronously advance underwater along with the hull structure to complete fishing; and in the fishing process, the spiral driving structure can synchronously advance along with the fishing structure, the spiral driving structure can be stressed to automatically generate rotating kinetic energy when advancing, the rotating kinetic energy is transmitted to water in the fishing structure, the water is stirred to spirally flow backwards, catches entering the fishing structure are gradually shunted to a plurality of different positions formed by separating the interior of the fishing structure by the inner cavity partitioning structure along with the water flow which spirally flows backwards, so that the dispersion degree of the catches in the fishing structure is improved, and the possibility that the catches are concentrated to the rear part of the fishing structure to cause extrusion deterioration is effectively reduced.

    本发明公开了一种应用于海洋渔业工程的渔船拖网内部防挤压捕捞方法,属于海洋工程方法技术领域。包括牵引结构、捕捞结构、内腔分区结构及螺旋驱动结构;通过牵引结构将船体结构与捕捞结构传动相连,使得捕捞结构在水下能够跟随船体结构同步前进完成捕捞;在捕捞过程中,螺旋驱动结构能够随着捕捞结构同步前进,且螺旋驱动结构在前进时能够受力自动产生旋转动能,并将旋转动能传递至捕捞结构的内部水中,使水受拨动螺旋向后流动,进入捕捞结构内的渔获物随螺旋向后流动的水流逐步被分流至由内腔分区结构分隔捕捞结构内部形成的若干个不同位置,提高了渔获物在捕捞结构内的分散程度,有效降低了渔获物集中至捕捞结构的后部造成挤压变质的可能性。
