Problems solved by technology

[0007] However, in these existing fish-collecting lights, all are fish-collecting lights that only attract concentrated fish, and do not necessarily help to improve fishing efficiency.

Embodiment 1

[0043] in such as Figure 6 The interior of the circular tank P (380 cm in diameter, 100 cm in depth, and 90 cm in water depth) filled with seawater shown was tested after acclimatizing calamari to the darkness for 2 hours. The test was performed by irradiating the squid in the water tank P with blue light from the light source 20 . In addition, the light emission conditions of the light source were set to a period of 0.5 s (lighting time 0.25 s, light extinguishing time 0.25 s). In addition, as the light source 20, a light source in which 30 chip-type LEDs (Sharp Corporation, GM5WA06270A) are mounted on a board is used. In addition, the emission wavelengths of the blue, green, and red light sources are respectively blue 462 nm, green 517 nm, and red 622 nm, and the luminosity is 3000 mcd.

Embodiment 2

[0045] As the light emission conditions of the light source, the same implementation as (Example 1) was performed except that the light emission color was blue and the cycle was 0.5s (the lighting time was 0.38s, and the lighting time was 0.12s).

Embodiment 3

[0047] As the light emission conditions of the light source, the same implementation as (Example 1) was performed except that the light emission color was blue and the cycle was 1.0 s (the light-on time was 0.5 s, and the light-off time was 0.5 s).

Abstract

The present invention provides a method to improve the fishing efficiency and a fish-gathering lamp equipment used for this method. This fish-gathering method characterized in that it tempts the sleeve-fish and other marine lives which possess phototoxy to the place next to the lamp-house, light the intensity-regulated lamp at scheduled shining time with scheduled shining cycle to tempt the gathered marine lives so that the marine lives become paralyzed. Furthermore, the lamp equipment for the above-mentioned fish-gathering method characterized in that it have one lamp-house at least, a glittering period-controlling part which controls the glittering period of above-mentioned lamp-house, and a glittering time-controlling part which controls the glittering time of above-mentioned lamp.

Description

technical field [0001] The invention relates to a fish collecting method for fishery and a fish collecting light device used therein. Specifically, it belongs to the technical field of fish-collecting light devices for gathering aquatic animals such as squid, saury, horse mackerel, mackerel, etc., and related to fishing. Background technique [0002] Conventionally, the purpose of using a fish-collecting light in fishing operations is to gather as many target organisms as possible from the wider sea area around the ship into the operation range of the fishing gear and fish them. The fishery operation process consists of the process of detecting target organisms (fish detection), the process of attracting and concentrating (fish collection), and the process of catching fish (fishing). The light of the fish collection light is an important factor that affects fishing efficiency. . Examples of the main target organisms of Jiyudeng fishery include phototaxis squid, saury, hors...
