Method for improving water quality in aquaculture

Abstract

The invention relates to the technical field of aquaculture, in particular to a method for improving water quality in aquaculture, which comprises the following steps: S1, crushing a water quality modifier, adding sweet potato starch and water, uniformly mixing, putting into an extruder, extruding, and preparing into spherical water quality improving balls by a rounding machine; and s2, uniformly throwing water quality improving balls into water once every 15 days, wherein the throwing dosage is 1-2.3 kg / 1m water depth per mu of water surface; wherein the water quality improver is prepared from the following raw materials in parts by weight: 25 to 35 parts of EM bacteria, 20 to 25 parts of probiotic, 25 to 30 parts of bacillus subtilis, 15 to 25 parts of faecalis coccus, 10 to 15 parts of an algae growth accelerant, 10 to 12 parts of a compound oxygen supply agent, 10 to 20 parts of a heavy metal adsorbent and 10 to 12 parts of a photosynthesis accelerant. According to the present invention, the surface tension of the water body can be reduced, the oxygen absorption capacity of the water body can be improved, the excessive aging of algae in the water can be prevented, and the photosynthetic efficiency of aquaculture can be improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for improving water quality in aquaculture. Background technique [0002] my country is a big fishery country in the world. In recent years, the aquaculture industry has developed rapidly, and intensive high-density farming has become a development trend. However, it also leads to the destruction of the ecological environment of aquaculture. Due to lack of attention to planning, unreasonable breeding methods, blind pursuit of high density and high yield, excessive use of feed and medicine, seriously exceeding the carrying capacity of water bodies, fish diseases and water quality problems continue to worsen. The residues of drugs and feed, the excrement of organisms, the accumulation of dead bodies and organic residues lead to serious pollution of water bodies. The quality of water directly affects the health of aquatic animals. With the deepening of the concept of e...

Problems solved by technology

[0003] After the existing water quality improvers are put into use, the photosynthetic effect on the underwater algae plants is not strong, which leads to the frequent emergence of aquatic animals at night, and the water quality improvers cannot reduce the surface tension of the water body , so that the ability to dissolve oxygen in the water body is low, which will lead to the aging of algae in the water
