Problems solved by technology

In order to increase the aquaculture output per unit water body, one-sided pursuit of high yield often excessively increases water body nutrition, excessive baiting, fertilization, and increased stocking density, resulting in a sharp increase in nitrogen and phosphorus content in water, decreased transparency, and water quality deterioration. The bait and cultured species in the water body A large number of metabolites accumulate at the bottom of the pond, causing serious pollution
If things go on like this, the natural ecology of the water body is destroyed, aquatic animal diseases spread in the breeding space, aquatic animal diseases occur frequently, and fishery losses are huge
[0003] In order to prevent diseases, it is common to use fish medicines in the whole breeding cycle at present, but the use of fish medicines can only be used as a temporary solution, and it brings more ecological consequences such as drug resistance and accumulation of residues in aquatic products and the environment, forming Vicious circle, no fundamental improvement

Embodiment 1

[0036] A method for improving the aquaculture environment, comprising the steps of:

[0037] (1) Drain the water in the pond, clean the bottom of the pond, introduce clean water to a water depth of 5cm, sprinkle electrolytic water for sterilization, and drain the water in the pond again;

[0038] (2) Evenly lay a layer of pool bottom material on the bottom of the pond, and then evenly spray a layer of expanded vermiculite suspension;

[0039] (3) Slowly inject clean water to a water depth of more than 1.5m, and then put compound microorganisms and compound active enzymes into the pond.

[0040] Among them, the electrochemical water in step (1) is prepared by using electrochemical water treatment equipment to prepare a sodium chloride solution with a mass concentration of not less than 2‰, and the indicators are as follows: the mass concentration of available chlorine is 70mg / L, and the concentration of ozone is 3mg / L , pH 6.5, redox potential 900mV, hydrogen peroxide 15mg / L. ...

Embodiment 2

[0057] (2) Evenly lay a layer of pool bottom material on the bottom of the pond, and then evenly spray a layer of expanded vermiculite suspension;

[0058] (3) Slowly inject clean water to a water depth of more than 1.5m, and then put compound microorganisms and compound active enzymes into the pond.

[0059] Among them, the electrochemical water in step (1) is prepared by using electrochemical water treatment equipment to prepare a sodium chloride solution with a mass concentration of not less than 2‰, and the indicators are as follows: the mass concentration of available chlorine is 100mg / L, and the concentration of ozone is 4mg / L , pH 7.5, redox potential 1100mV, hydrogen peroxide 20mg / L...

Embodiment 3

[0074] A method for improving the aquaculture environment, comprising the steps of:

[0075] (1) Drain the water in the pond, clean the bottom of the pond, introduce clean water to a water depth of 6cm, sprinkle electrolytic water for sterilization, and drain the water in the pond again;

[0076] (2) Evenly lay a layer of pool bottom material on the bottom of the pond, and then evenly spray a layer of expanded vermiculite suspension;

[0077] (3) Slowly inject clean water to a water depth of more than 1.5m, and then put compound microorganisms and compound active enzymes into the pond.

Abstract

The invention discloses a method for improving an aquaculture environment. The method for improving the aquaculture environment mainly comprises the three steps of cleaning the bottom of a pond and using electrified water to conduct sterilization treatment, making the bottom of the pond paved with a pond bottom material and spraying expanded vermiculite suspension liquid, throwing composite microorganisms and composite active enzyme after water is injected, the three steps are indispensable, and cannot be reversed, every step goes forward one by one, all the steps are are linked with one another, and therefore the aquaculture environment is improved.

Description

technical field [0001] The invention relates to a method for improving the aquaculture environment. It belongs to the technical field of aquaculture. Background technique [0002] my country's aquaculture industry is developing rapidly, and it is the only large fishery country in the world where the aquaculture output exceeds the fishing output. At present, domestic aquaculture is dominated by the traditional aquaculture model, which is characterized by "dense, mixed, and round", which is a backward aquaculture model that obtains high yields through multi-species, high-density and large-scale fertilization and feeding. In order to increase the aquaculture output per unit water body, one-sided pursuit of high yield often excessively increases water body nutrition, excessive baiting, fertilization, and increased stocking density, resulting in a sharp increase in nitrogen and phosphorus content in water, decreased transparency, and water quality deterioration. The bait and cul...
