Method and device for increasing oxygen in pond

Abstract

The invention discloses a method and a device for increasing oxygen in a pond, which are characterized in that an inflation oxygen increasing method is used and a light pest attracting device is arranged at an air suction port of an inflation oxygen increasing device, so that attracted pests are sucked into water and fish stocks attracted by the light pest attracting device eat and kill the pests in the water, and thus, when the oxygen increasing work is completed, the effects of killing the pests and feeding fishes are achieved. According to the invention, various ecological benefits can be realized when the oxygen increasing work of the pond is completed.

Description

technical field [0001] The invention relates to a pond aeration method and a device thereof, in particular to an aeration method and a device for fish ponds. Background technique [0002] Pond aquaculture has a history of thousands of years in my country and is the leading aquaculture method for freshwater aquaculture. At present, my country's pond culture area is 2.429 million hectares, with a total output of 13.31 million tons, accounting for 72% of my country's total freshwater aquatic product output. But pond culture has many problems. Among them, the problem of hypoxia in ponds is particularly prominent. In order to pursue benefits, the density of pond culture is relatively high, so it is easy to cause the death of fish due to hypoxia. In summer, it is often seen that a large number of fish schools float up and exhale. For this reason, various methods of increasing oxygen emerge in an endless stream. However, the purpose of various aeration methods is relatively sin...
