North Pacific Ocean laying net fishery fish shoal following lamp capturing method based on light mixed configuration of metal halide lamps and LED lamps

Abstract

The invention discloses a method for capturing a fish shoal following lamp in net laying fishery in North Pacific Ocean based on mixed light configuration of a metal halide lamp and an LED (Light Emitting Diode) lamp, which is characterized in that the LED lamp with adjustable light color and brightness is newly researched and developed, and the LED lamp is mainly an underwater lamp; the LED lamp is formed by five LED light-emitting modules to emit light at an angle of 540 degrees; the LED underwater lamps are distributed on the two sides of a ship board, and the light brightness and color of each LED lamp are controlled through an independent switch and an independent regulator. The color of the LED lamp is white light, blue light or dark green light; the overwater lamps are installed on the two sides of the ship top, and all the overwater lamps are turned off after the fish gathering task is completed; and the underwater lamps are sequentially turned off to guide fish schools into fish guiding lamps at the stern. Based on a light mixing configuration method of the metal halide lamp and the LED lamp, the advantages of the metal halide lamp and the LED lamp are exerted, a novel underwater lamp is researched and developed, and an implementation scheme and an operation method for fish shoal lamp following in net laying fishery are constructed, so that the purposes of improving the production efficiency and the yield are achieved.

Description

technical field [0001] The invention belongs to the technical field of fish-collecting lamps for marine fishery, and in particular relates to a method for catching fish schools and lamps in North Pacific net-laying fishery based on the mixed configuration of metal halide lamps and LED lamps. Background technique [0002] The North Pacific net fisheries mainly catch sardines and Japanese mackerel, accounting for more than 95% of the production. In 2021, sardines will account for more than 70%. At the same time, fish schools do not follow the lights in the North Pacific net fishing industry, that is, fish schools do not follow the lights of underwater lights and move, thereby reducing the probability of fish schools entering the net mouth. The output is reduced, and this phenomenon may have a frequency of about 30 operations. The reasons for the preliminary analysis are as follows: 1) The water temperature is too low; 2) The fish is small; 3) The wind and waves are strong; 4)...

In 2021, sardines will account for more than 70%. At the same time, fish schools do not follow the lights in the North Pacific net fishing industry, that is, fish schools do not follow the lights of underwater lights and move, thereby reducing the probability of fish schools entering the net mouth. Reduced output, this phenomenon may have a frequency of about 30 operations

[0003] 5) Metal halide lamp color is white light, not adjustable

Due to the difficulty in the application of high-power LEDs in high seas fisheries, a very important reason is that there is a partial gap between the fish-collecting effect and traditional metal halide lamps, and it cannot be repaired and replaced in a short time. Therefore, the present invention is based on metal halide lamps and LED lamps. The mixed configuration method of lights and lights, taking advantage of the advantages of their respective fish-collecting lights, developed a new type of underwater lights and constructed the implementation plan and method of fish schools and lights in net-laying fishery, so as to achieve the purpose of improving production efficiency and output
