Biological preparation for balancing water quality for aquaculture

Abstract

The invention discloses a biological preparation for balancing water quality for aquaculture. The biological preparation comprises the components of: sodium humate accounting for 49 percent, sodium thiosulfate accounting for 35 percent, biological flocculants accounting for 10 percent, bacillus subtilis accounting for 3 percent, streptococcus faecium accounting for 3 percent, wherein the bacillus subtilis is 3,000,000,000 / g and the streptococcus faecium is 3,000,000,000 / g. According to the biological preparation, the nutrition of a water body is balanced, the water quality is improved, the blue-green algae outburst is controlled, the growth of beneficial algae is activated, dissolved oxygen of the water body is increased, the content of beneficial microorganisms in the water body is increased, the occurrence of chronic nitrate and nitrous acid poison incidents of fishes can be prevented, the immune globulin and the antibody level of the fishes are improved, and the herd immunity of the fishes is improved; and by adding the streptococcus faecium, the true nutritive value of feed is improved, the concentration of ammoniacal nitrogen in excrements also can be reduced, and the pollution to the water quality is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a biological agent for balancing water quality in aquaculture. Background technique [0002] With the rapid development of the aquaculture industry, especially the development of large-scale high-density aquaculture today, the proportion of aquaculture in the aquaculture industry is increasing. Due to the continuous expansion of market demand, the aquaculture density of aquaculture farmers is also increasing. With the continuous increase of aquaculture density, the deterioration of water quality cannot be ignored, mainly manifested in: water pollution caused by fish feces, and the impact of human domestic sewage and agricultural sewage, resulting in water quality deterioration. The water quality of some farmers has seriously deteriorated, and the aquaculture parameters such as ammonia nitrogen, nitrite, and dissolved oxygen in the water continue to deteriorate; the degree of ...

Problems solved by technology

However, there are few types of biological agents currently used to balance water quality in aquaculture. At present, antibiotics are used too much in the aquaculture process. Long-term use will reduce water quality and affect the growth of fish in aquaculture.
