After identification, a total of 41 species were caught by the four solar powered underwater fishing lights.
The LED white light group caught a total of 31 species, including 26 species of fish,
2 species of cephalopods, 2 species of shrimp, and 1 species of crab, belonging to 8 orders, 19 families and 26 genera;
green light group caught a total of 37 species, including 31 species of fish,
2 species of cephalopods, 2 species of shrimps, and 2 species of crabs, belonging to 9 orders, 22 families and 30 genera;
LED blue light group caught a total of 33 species, including 26 species of fish,
2 species of cephalopods, 2 species of shrimps, 2 species of crabs, and 1 species of mantis shrimp, belonging to 9 orders, 19 families and 26 genera;
A total of 21 species were caught in the metal halide lamp group, including 16 species of fish.
2 species of cephalopods, 2 species of shrimp, and 1 species of crab, belonging to 6 orders, 12 families and 18 genera.
solar powered underwater fishing lights catch rate:
It can be seen that LED solar powered underwater fishing lights have the highest catch rate of 10.896 kg/h.
followed by LED green lights, LED blue lights and metal halide lights.
It can be seen that the catch rate of LED fish-collecting lamps is higher than that of metal halide lamps.
and the catch rate of LED white light lamps is significantly higher than that of other groups.
It is 1.64 times of LED green light, 1.86 times of LED blue light, and 4.26 times of metal halide lamp;
The catch rate of LED green lights is slightly higher than that of LED blue lights;
the catch rate of metal halide lights is significantly lower than that of other types of fish-collecting lights.
solar powered underwater fishing lights difference:
There were differences in the number and species of dominant species in the catches of the four Jiyudeng species.
Chinese calamari is a common dominant species. After analyzing its catch rate.
it is found that the catch rate from large to small is LED white light, LED green light, metal halide light, and LED blue light.
The Chinese squid catch rate of LED white light is much higher than that of the other three fish collection lights.
which is 3.39 times that of LED green light, 4.30 times that of metal halide light, and 7.07 times that of LED blue light.
One-way analysis of variance was performed on the carcass lengt.
and body weight between individuals captured by LED lamps and individuals captured by metal halide lamps.
It was found that there was no significant difference in carcass length (p>0.05) .
and body weight (p>0.05) between individuals captured by LED white light lamps and metal halide lamps;
was no significant difference in carcass length (p>0.05) .
and body weight (p>0.05) between individuals captured by LED green light and metal halide lamp;
There were significant differences in carcass length (p < 0.05) .
and body weight (p < 0.05) between individuals captured by LED blue light and metal halide lamp.
