Marine Lighting Science | How much impact does lighting have on offshore fishing?

1. Lighting and offshore fishing

Starting from May 1, many sea areas in my country have entered the summer fishing moratorium. The fishing moratorium falls in the summer season, when the temperature is high and the sunshine is sufficient, which is conducive to the reproduction of marine algae and ferns, and there is sufficient food for fish. In addition, the spawning period of fish is mostly in summer, and the fishing moratorium in the summer season can better allow fish to reproduce.

With the arrival of July, the weather is getting hotter and the fishing season has begun in many places. As you taste the delicious seafood on the table, do you know that lighting also plays an important role in ocean fishing? Now, let the editor take you to understand these things about "fishing".

2. "Phototaxis" of fish

Many fish have phototaxis, but what they really like is some low light. Fishing boats that use lights to round up and lure fish operate at night, taking advantage of the "phototaxis" of animals.

3. Underwater “Light Field”

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

4. Squid on the Dinner Table

Do you know how the squid you love to eat is caught from the sea? This marine mollusc with a lifespan of only one or two years actually contributes more than 500,000 tons of high-quality protein to my country's fishery every year. And fishing for squid is also a technical job. There are a series of requirements from methods, methods to tools.

5. Good tools lead to good harvests

Fishing by luring fish with light has become a very common method of operation, especially in distant water fisheries. The fish-gathering lamp is an indispensable product in the light fish luring operation. With the continuous development of lighting technology, the corresponding fish-gathering lamp products have also been updated and iterated.
