Progressive lamplight fish luring system and progressive fish gathering method

Abstract

The invention provides a progressive lamplight fish luring system and a progressive fish gathering method. The progressive lamplight fish luring system comprises a support, a plurality of lamp holdersare fixed to the support in a rigid mode, vertically-downward cylindrical rod-shaped metal halide lamps are inserted below the lamp holders through lamp caps, and side reflectors with arc-shaped plate-shaped horizontal sections are arranged on the backs, back on to the ocean surface, of the metal halide lamps. The lamp holder is connected in a rotating shaft mode relative to the lamp holder, so that the rod-shaped metal halide lamp can obliquely swing in a stepped or electrodeless mode in the direction towards the fishing ship or away from the fishing ship around a rotating shaft arranged inthe horizontal direction. In the fish gathering process, the metal halide lamp can swing, so that the irradiation range of the metal halide lamp moves from far to near, fishes at a far position can follow light beams to gather around a fishing ship, the fish gathering range is enlarged, and the fish gathering effect is improved.

Description

Technical field [0001] The invention relates to the field of aquatic equipment, in particular to a progressive light fish attracting system and a progressive fish collection method. Background technique [0002] In the production of marine fishing, fishing boats use lights to attract fish, and use the phototaxis of fish to attract fish to the vicinity of the fishing boat for fishing, which is a conventional fishing operation. The energy cost consumed by light trapping occupies an important proportion of the overall fishing cost. The metal halide fish collecting lamp is the most commonly used fish collecting lamp in current marine fishing production. [0003] The fish-collecting lamp used for light lure fish is usually hung above the ship’s side. The light of the traditional fish-collecting lamp illuminates all around evenly, and the effective utilization of light energy irradiated on the water surface and underwater is very low. It needs to be further improved through technical im...

AI Technical Summary

Problems solved by technology

[0006] The light energy of the fish-collecting lights on the deck of the fishing boat not only does not contribute to fishing production, but also produces strong light pollution and high heat on the deck, which seriously damages the health of deck operators, and should be protected by technical means

[0007] In addition, in the prior art, the fishing lights are usually fixed, and the irradiation range cannot be deflected, and can only be concentrated in the area close to the fishing boat, so the effect of collecting fish is limited
