Embodiment 1

[0043] The squid was acclimatized inside a circular tank P (380 cm in diameter, 100 cm in depth, and 90 cm in water depth) filled with seawater as shown in FIG. 6 , and the test was carried out after making it adapt 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 invention provides a method capable of improving fishing efficiency and a fish-collecting light device used in the method. This method of collecting fish is characterized in that aquatic animals such as phototaxis squid are lured and concentrated near the light source, and light of a predetermined luminous intensity is irradiated with light of a predetermined flashing cycle at a predetermined lighting time to attract the concentrated aquatic animals, so that the aquatic animals become paralyzed. In addition, the fish-collecting light device used in the above-mentioned fish-collecting method is characterized in that it has at least one light source, a flicker cycle control unit for controlling the flicker cycle of the light source, and a device for controlling the lighting time of the light source. Lighting time control unit.

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...
