Operating method of Pacific saury stick-held net

Abstract

The invention relates to an operating method of a Pacific saury stick-held net. The operating method includes the steps of observing fishes, attracting the fishes, casting the net, connecting a guide headrope to a winch, connecting the guide headrope to upper and lower headropes after passing the guide headrope by a fixed pulley on a boat body and a fixed pulley on a support pole, laying netting, the upper and lower headropes and a lift headrope, using the guide headrope to stretch the netting until full stretching, attracting the fishes into the netting, drawing in the net, using the winch to quickly wind up the upper and lower headropes through the lift headrope after guide lamps move to an end, turning off the guide lamps, using the winch to winch the upper and lower headropes and the lift headrope to the stern through the guide headrope, stopping winching the netting after the fishes gather at a collecting portion, and putting down a suction pump to suck the fishes onto a deck. The netting is controlled to stretch so as to spread the net, through the support pole and the guide headrope wound on the fixed pulleys, less time and labor is consumed, the fixed pulleys are positioned through the support pole, and a catching range is widened.

Description

technical field [0001] The invention relates to a fishing operation method, in particular to an operation method for lifting a net on a saury side. Background technique [0002] Saury is widely distributed in the North Pacific Ocean and its coastal waters. It is one of the important pelagic fish species in my country, Japan, Russia, and South Korea. The fishing operation of saury is mainly carried out with the fishing net of saury. [0003] The side lift net belongs to the floating netting method, and its shape is usually square or rectangular. The edge net, the upper edge net is connected with the upper line, the lower edge net is connected with the lower line, the upper line is connected with the floating rod, and the lower line is connected with the sinker. The net is stretched open to utilize the phototaxis of the saury, and a fishing light is installed on the fishing boat to lure the fish, and then the net is used for fishing. [0004] This kind of net operation metho...

AI Technical Summary

Problems solved by technology

[0005] But there are following two aspects problems in this side lifting net operation method: on the one hand owing to be to stretch the net clothing by the movement of floating rod, so the width of net clothing generally corresponds to floating rod, and because floating rod is fixed on The reamer on the boat pushes the floating rod away. When the net is to be collected, the reamer is also used to retract the floating rod. Therefore, the length of the floating rod cannot be greater than the length of the side of the ship, otherwise the floating rod cannot be driven to move, which limits the fishing range. Restricted, low fishing efficiency; on the other hand, many people need to work together to complete the operation, and the labor cost is high
