A sinking and floating flexible net structure fixed net fish picking device and its use method

Abstract

The present invention relates to the technical field of fishing tools, and discloses a sinking-floating flexible net structure fixed net fishing device, comprising an inflatable planar net body arranged at the bottom of the fixed net, and the inflatable planar net body is provided with ventilation The vent is communicated with the air compressor through the connecting pipe, and the air compressor is used to inflate the inside of the inflatable planar mesh body or draw air from the inside of the inflatable planar mesh body through the vent connected with the connecting pipe. A plurality of anchors are evenly spaced on both sides of the inflatable planar net body along the gas flow direction when inflated, and the inflatable planar net body is gradually floated along the gas flow direction when inflated by the buoyancy of water , the floating part squeezes the fixed net gradually, and the volume of the fixed net decreases gradually, or the inflatable planar net body gradually falls along the flow direction of the gas during pumping, and the falling part gradually breaks away from the fixed net, and the volume of the fixed net Gradually increase.

Description

technical field [0001] The invention belongs to the technical field of fishing tools, and in particular relates to a sinking-floating flexible net structure fixed net fishing device and a method of use. Background technique [0002] Set net is a kind of trap fishing gear, which has attracted wide attention due to its low ecological impact and low fuel efficiency. According to the living habits of the fishing object and the hydrological conditions of the operating water area, the net gear, piles, anchors, etc. are laid in places near the sea or near the mouth of the fish where fish schools pass by. The fixed net is composed of a net wall to induce and block fish, a lifting net and a funnel net to guide fish into the net bag, and a rear net circle and a fish-taking part for collecting fish. The net wall extends from the coast to the waters nearly 100 meters deep. Usually, the scale of fishing gear is relatively large, and the fishing area where the final catch is collected is...
