Slowly-released microorganism water quality improver for aquaculture and preparation method of improver

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a lowly-released microorganism water quality improver for aquaculture and a preparation method of the improver. The improver is prepared from, in weight percentage, 30%-50% of compound microorganism bacterium agents, 40%-60% of nutritional agents, 1%-5% of thickening agents and 1%-10% of stabilizers, and the number of microorganism living bacteria exceeds 2 billions / g. according to the improver, harmful substances effecting growth and reproduction of fishes in water are utilized, transformed and degraded by the aid of growth and metabolism of functional microorganisms, so that the water is purified, the lowly-released microorganism water quality improver overcomes shortcomings of a traditional biological improver, large fluctuation of water indexes is avoided, abnormal physiological reaction of aquaculture animals is avoided, influence of external factors such as water temperature, water quality and drug residues on action effect is reduced, the improver is long in action period and can keep water environments for a long time, and aquaculture cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a slow-release microbial water quality improver for aquaculture and a preparation method thereof. Background technique [0002] my country is a big fishery country in the world, and it is also a big aquaculture country in the world. In recent years, aquaculture industry has developed rapidly, and intensive high-density farming has become a development trend, but 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 ...

Problems solved by technology

However, the use of microbial preparations is greatly affected by external conditions such as temperature and drug residues. The use requirements are high, and the actual effect will fluctuate greatly. Moreover, the growth of microorganisms requires oxygen, and the mass reproduction after use will lead to a decline in dissolved oxygen in water. , and the metabolites produced at the same time will change the pH environment of the water body and cause a certain degree of impact on aquatic animals
