Water quality improver for aquaculture and preparation method thereof

Abstract

The invention provides a water quality improver for aquaculture and a preparation method thereof, and belongs to the technical field of aquaculture. The water quality improver includes immobilized algal fungal pellets, corn, carrot, nitrifying bacteria, amino acids and chitosan. The preparation method includes the steps: drying corn and carrot in the sun, and smashing the corn and carrot into powder after 500-800 MHz microwave treatment; mixing chitosan and amino acids with the powder, adding the nitrifying bacteria after ball milling for 2-3 h, then continuing to carry out ball milling for 50-70 min, and thus obtaining a powder mixture; and preparing spherical particles from the powder mixture by a particle preparation machine, then mixing with the immobilized algal fungal pellets evenly,and thus obtaining the water quality improver. The water quality improver can remove nitrogen, phosphorus and organic substances from aquaculture water, inhibits the growth and reproduction of pathogenic microorganisms, decomposes harmful substances and purifies the water quality; the preparation method can improve the preservation period of the prepared water quality improver and improve the useeffect of the prepared water quality improver.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aquaculture water quality improver and a preparation method thereof. Background technique [0002] Under the background of rapid development of aquaculture industry, continuous expansion of aquaculture area, overload of aquaculture capacity, and traditional aquaculture methods still leading the industry, organic matter such as residual bait, feces, and biological debris in aquaculture ponds continues to accumulate at the bottom of the pond, and organic matter is in anoxic state. Ammonia nitrogen, nitrite, hydrogen sulfide and other toxic products formed by incomplete oxidation under the environment endanger the life and life of aquatic animals. According to incomplete statistics, the total area of ​​my country's inland waters is 17.47 million hectares, of which 6.75 million hectares can be cultivated, and 5.66 million hectares have been utilized, with a utiliza...

AI Technical Summary

Problems solved by technology

First of all, basic research is still relatively weak, lack of systematic research, research on mechanism of action, residual toxicology, etc. is relatively small, and there is a lot of blindness in use (Wang Hongwei et al., 2011), such as chlorine preparations are easily affected by organic matter. The "three causes" (carcinogenic, teratogenic, mutagenic) chlorinated substances, and their existence, are also very irritating to aquatic animals (Ma Shirong et al., 2007). Residues of metal ions, such as metal ions, cause safety hazards to the health of farmed animals and animal food

Secondly, the market of water quality regulators is chaotic, and the phenomenon of indiscriminate use and abuse is serious, threatening the safety of aquatic products

Improper use control will easily cause serious damage to the water body environment, aggravate the deterioration of the water body environment, cause the survival rate of farmed animals to decrease, slow down the growth rate, etc., and seriously affect the economic benefits of aquaculture.

Finally, there are still problems such as irregular management and unsound relevant standards for aquatic medicines.

There are many names of water quality regulators. Due to the large differences in raw materials and production processes, many of them do not have unified industry standards and national standards. In particular, the screening and cultivation of microecological preparations are complicated, and the quality is uneven. Due to the concentration of bacteria, The recovery rate is unstable, microorganisms are greatly affected by the external environment, and the ability to resist adverse environments is poor, which leads to unstable use of microbial water quality improvers, which can not achieve the purification effect, and may lead to strain variation and the emergence of potential diseases
