The working principle of the black light lamp is the same as that of the ordinary fluorescent lamp. It is also composed of a ballast, a starter, a lamp tube, and a lamp holder. The difference is that the lamp tube is black, and the emitted light is less than the incandescent light, but a kind of pair. The insects have light with strong attraction. Just put the black light on a height of about 50 centimeters from the water surface, put a rainproof shed on it, turn on the power supply, and switch at night. The flying insects will be within a radius of 5 kilometers around the light, especially the moth will automatically fly to the light. However, when it comes to falling under the lamp, it is eaten by the freshwater fish and it is particularly effective. The required electricity consumption is only 0.2 per 10 o'clock (that is, from dark to bright night), but the flying insects introduced can reach about 10 kilograms, and sometimes even more, greatly reducing the cost of planting freshwater and whitefish breeding feed, and relatively increasing the economy. Benefits are worth promoting and applying.
In short, there are many ways to improve the economic benefits of freshwater fish breeding. The situation varies from place to place and the methods vary. Everyone should start from the actual conditions of the local area and work hard to save costs and improve technology. I believe that the economic benefits of freshwater fish breeding will be higher and higher, and the area for freshwater fish breeding will also grow.
