Embodiment 1
[0023] Principle: (1) According to the phototaxis principle of the golden squid, determine the suitable illumination range of the golden squid, so as to determine the amount of polypropylene (PP) added to the luminous plastic masterbatch.
[0024] (2) The principle of quasi-living erbium formed by the swing of chilled erbium material on the device caused by water flow and air inflation.
[0025] The specific configuration method is as follows:
[0026] 1. Determine the suitable illumination range for golden squid
[0027] The size of the test plastic water tank is 240cm×40cm×40cm, and the two ends are plexiglass walls. Except for the side wall of the light source, the other inner sides are pasted with black screening cloth to prevent light reflection in the box. The light source is a 100W incandescent lamp. Different horizontal light gradients are obtained by adjusting the power supply voltage through the TDGC-3 voltage regulating transformer and artificially adjusting the di...
Embodiment 2
[0037] The technical solution of this embodiment includes the following steps: making the food attracting device, combining the food attracting device with bait, illuminating light, and applying.
[0038] 1. Manufacture of food-attracting device
[0039] The lure device comprises a float, a string, a soft fluorescent plastic clip 1 and a soft fluorescent plastic clip 2;
[0040] The float, a 5 cm diameter spherical plastic, has a knotted earring ( image 3 );
[0041] Described thin rope is a nylon rope, is 20cm long, and has good flexibility.
[0042] The soft fluorescent plastic card strip 1 is made of soft fluorescent plastic with a width of 0.5cm, a length of 40cm, and a thickness of 0.1cm. The ratio of polypropylene and luminous plastic masterbatch in the soft fluorescent plastic card strip is 1:2 ( That is, polypropylene: luminous plastic masterbatch = 1:2), there is a hole 5 with a diameter of 1mm on the top of the soft fluorescent plastic clip 1 for connecting strin...
Embodiment 3
[0049] The technical solution of this embodiment includes the following steps: making the food attracting device, combining the food attracting device with bait, illuminating light, and applying.
[0050] 1. Manufacture of food-attracting device
[0051] The lure device comprises a float, a string, a soft fluorescent plastic clip 1 and a soft fluorescent plastic clip 2;
[0052] The float, an 8 cm diameter spherical plastic, has a knotted earring ( image 3 );
[0053] Described thin rope is hemp rope, and length is 30cm, and has good flexibility.
[0054] The soft fluorescent plastic card strip 1 is made of soft fluorescent plastic with a width of 1cm, a length of 80cm and a thickness of 0.15. The ratio of polypropylene and luminous plastic masterbatch in the soft fluorescent plastic card strip is 1:1. The top of the plastic clip 1 has a small hole 5 with a diameter of 2mm, which is used to connect the string; the center of the soft fluorescent plastic clip 1 has 15 snaps ...
