Beginning on May 1, many sea areas in my country have entered the fishing moratorium during the low season. The fishing moratorium is in the low season, when the temperature is high and the sun is abundant, which is conducive to the reproduction of marine algae and ferns, and the food for the fish is sufficient. In addition, the spawning period of fish is mostly in summer, and the fishing suspension period can better allow fish to reproduce in the low season. With the arrival of July, the weather is gradually hot, and many places have ushered in the fishing season one after another, tasting the delicious seafood on the table. Did you know that lighting also plays an important role in ocean fishing? Let's come together next Learn about these things about "fishing".

       Many fish are phototaxis, but what they really like is some shimmer. The fishing boats that use lights to round up and lure fish operate at night, using the "phototaxis" of animals. Popular science of phototaxis: Phototaxis refers to the characteristics of animals producing directional movement to light stimulation.

       Positive phototaxis: directional movement towards the light source, such as: saury, sardines, blue round trevally, bamboo mackerel, cephalopods, etc. Negative phototaxis: Directional movement away from the light source, such as: oriental bonito, bream, pike, bonito, etc. ——Yu Wenzhao, "Phototaxis Physiology of Fish [M]"

       Due to the particularity of the environment, the characteristics of the light field formed by the fish-collecting lamp in the water have also been well studied. The light emitted by the fish-collecting lamp is absorbed and scattered by the sea water, forming a light field with a strong to weak intensity. People divide this light field into four parts according to its light intensity.
