Novel crayfish feeding method capable of reducing water pollution

Abstract

The invention discloses a novel crayfish feeding method capable of reducing water pollution, and belongs to the field of agricultural sewage treatment. According to the novel crayfish feeding method capable of reducing water pollution, a breeding area and a feeding area are included, an evenly-dispersed crayfish feed is spread on the feeding area, an eating area is arranged between the breeding area and the feeding area, a plurality of catching cages are placed in a water tank, the clean and safety of the crayfish breeding water are realized, and the problem that a water body is polluted is solved from the source; by using crayfish predation habits, feeding in water is changed to feeding on shore, the crayfish is forced to catch food on ashore, the situation of eutrophication of the waterbody due to excessive putting of feed in water is avoided, and waste of feed is avoided by feeding on shore; and in addition, the crayfish can be caught unexpectedly when eat, so that more efficiencyand convenience are achieved than a traditional ground cage capture method.

Description

technical field [0001] The invention relates to the field of agricultural sewage treatment, in particular to a novel crayfish feeding method which can reduce water body pollution. Background technique [0002] Agricultural sewage refers to the sewage or liquid substances discharged during the process of crop cultivation, livestock raising, and agricultural product processing, which affect human health and environmental quality. Its sources mainly include farmland runoff, feedlot sewage, and agricultural product processing sewage. Sewage contains various pathogens, suspended solids, fertilizers, pesticides, insoluble solids and salt, etc. [0003] At present, in addition to eating the food in the pond, the crayfish raised in the pond will also be fed with feed. The feed will be dissolved by water after being thrown into the pond, and the feed will not be completely eaten by the crayfish every time. There will be residues, and long-term feeding will cause eutrophication and ...

AI Technical Summary

Problems solved by technology

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a new crayfish feeding method that can reduce water pollution, which can realize the cleanness and safety of crayfish breeding water quality, and solve the problem of water pollution from the source , using the habit of independent predation of crayfish, changing feeding in water to feeding on the shore, forcing crayfish to go ashore to prey, avoiding eutrophication caused by too much feed in the water, and feeding on the shore can also avoid waste of feed , In addition, when crayfish are eating, they can be caught unexpectedly, which is more efficient and convenient than the traditional ground cage capture method
