A natural bait-free large-scale fish farming method for purifying drinking water sources

Abstract

Disclosed is a natural bait-free large-scale fish farming method capable of purifying the source of drinking water. A special device floating net combination is arranged in the water area of the source of drinking water, a natural fish bait storage and breeding bank is arranged in the floating net combination, a floating net and the natural fish bait storage and breeding bank are provided with a water flea inducing lamp and a mosquito inducing lamp, one third of natural fish bait can be stored, and the natural fish bait can breed by itself to be eaten by fish on an outer net of the floating net, so that the fish on the floating net has the same nature environment growth mode as wild fish. All bacterium plankton, microorganism and various insects harmful to the human health in the water are delicious food for fish, the fish can grow, the water area of the source of drinking water is purified, and if the fish grows well, it means that the water quality of the water area is good, so that people can drink the drinking water without worries. The natural bait-free large-scale fish farming method and device do not need any artificial fodder, and one person can manage the area of more than three square kilometers. As no artificial fodder is used, environment protection and pollution prevention are realized, and the quality of the fish is the same as that of wild fish.

Description

technical field [0001] The invention belongs to a fish farming method and device, in particular to a bait-free large-scale fish farming method for purifying drinking water sources. Background technique [0002] With the rapid development of my country's industrial and agricultural modernization, it has brought great damage to water resources, and industrial pollution has been well controlled under the guidance of the government, but an effective solution to agricultural pollution has not yet been found. The most serious agricultural pollution is fish farming in cages. Where there are fish farming in cages, the waters will be polluted. [0003] Because the water quality of the polluted water source is getting worse every year, the consequences of allowing this kind of cage fish farming to continue to develop will be unimaginable, and it will harm future generations. [0004] The existing fish farming industry all uses fish bait to feed, which causes environmental pollution o...
