Embodiment Construction

[0017] The present invention will be further explained below in conjunction with the drawings in the specification:

[0018] The artificial fish collection device for tuna purse seine fishery includes a float 1, a net piece 4 arranged under the float, and a positioning buoy 2 connected with the float. A number of sets of traps are arranged under the float 1. The trap consists of a string The bait box 6 is connected with each other. The bottom of the bait box 6 is provided with a sinker 9; the side and bottom sides of the net 4 are equipped with fish collecting lights 3, and a plurality of deep-water cameras are also arranged on the net 4, and the deep-water cameras are distributed It is arranged on both sides of the net piece 4; the fish collecting device is equipped with a controller, which is connected with the bait box 6, the fish collecting lamp 3 and the deep-water camera. The controller controls the feeding of the bait box, the lighting of the fish-collecting lamp and the op...

Abstract

The invention relates to fishery foundation facilities, in particular to a tuna purse seine fishery fish collecting device. The tuna purse seine fishery manual fish collecting device is characterized in that a plurality of luring devices are arranged below a floater, each luring device is composed of bait boxes connected in series, and a sinker is arranged at the bottom of the bait box at the bottom layer. Fish collecting lamps are arranged at the side edges and the bottom edges of net pieces; a plurality of deepwater cameras are also arranged on the net pieces; a controller is arranged on the fish collecting device, and the controller is connected with the bait boxes, the fish collecting lamps and the deepwater cameras. According to the tuna purse seine fishery manual fish collecting device, due to the fact that the bait box is arranged, fish schools are kept swimming around the floater to attract a new fish school, and the fish school maintenance force of the manual fish collecting device is improved; meanwhile, the phototaxis of the tuna is used, the cluster size is increased through the function of the fish collecting lamps, and therefore the effect of luring the fish schools is enhanced; due to the fact that the deepwater cameras are arranged on the net pieces, the yield of fishing through nets at a time and fishing efficiency are improved, and the purpose of reducing cost and improving benefits is achieved; the materials are automatically added in the bait boxes, and the heavy work of manual bait loading is omitted.

Description

Technical field [0001] The invention relates to a fishery infrastructure, in particular to a tuna purse seine fishery artificial fish collection device. Background technique [0002] Artificial fish collection device, FAD in English, is a device used to round up tuna on a large scale. Because tuna has the habit of gathering around floating objects, people have developed artificial fish collecting devices based on this habit to attract tuna, so that the yield and fishing efficiency of tuna seine nets can be significantly improved. [0003] The trapping capacity of artificial fish collecting devices determines the size of tuna fish clusters. Sometimes a single driftwood can collect tuna up to hundreds of tons and can be fished continuously for several times, so these fish collecting devices can continuously collect tuna populations. At present, the artificial fish collecting devices used by the purse seine fleet in our country are the traditional mode of floats and artificial nets, ...
