What is the effect of Zhengchang microecological preparations in aquaculture?

The application efficiency of microecological agents in aquaculture is very high, and it has the effect of preventing diarrhea, improving water quality and improving anti-stress ability. The results of the breeding test showed that the microecological preparation of fish and shrimp for Zhengchang aquatic products could significantly improve the shrimp and grass carp.

Yes, now it has been widely used, it is used to fertilize water, change the bottom is very good, and there are no drug residues, improve immunity.

Friend, you want to make it clear, for example, if I want to make a micro orange ecological preparation for the quiet drying, what conditions are needed. If you start the cave like this, we still have to talk about it...

Sterilization, disinfection, removal of harmful microorganisms such as wild trash fish.

How to use sodium thiosulfate in shrimp farming.

The amount of crab pond should be larger! Meters of deep water are generally used once before changing the bottom, one is to detoxify, and the other is to adsorb and increase the transparency of the water body. The effect of the bottom modification product is not affected by the upper part of the water body! Especially when it rains, the effect of muddy water is obvious!

I am a technical service for hairy crab breeding in Gucheng Lake! Any questions you can ask me!

Microecological preparations are live microbial preparations made by using normal microorganisms or substances that promote the growth of microorganisms. In other words, all preparations that can promote the growth and reproduction of normal microflora and inhibit the growth and reproduction of pathogenic bacteria are called "microecological preparations". It is of great help to the health and growth of animals, and there are many good microecological preparations on the market now, such as:

Shanghai Muxin Biotechnology****.

1. It can be used as a supplement for calcium in shrimp and crab farming.

2. Water quality management can be used to adjust the ratio of nitrogen and phosphorus in water.

3. Buffer, supplement phosphorus and calcium in the water body, which is conducive to shrimp and crab molting, and is of little use to herring and grass carp. It is mainly shrimp and crabs that supplement calcium.

Superphosphate, referred to as general calcium, is a phosphate fertilizer directly prepared by decomposing phosphate rock with sulfuric acid. The main useful components are the hydrate of calcium dihydrogen phosphate Ca(H2PO4)2·H2O and a small amount of free phosphoric acid, and also contains anhydrous calcium sulfate component (useful for sulfur-deficient soils).

Superphosphate contains 14% 20% of effective P2O5 (of which 80% and 95% are soluble in water), which is a water-soluble fast-available phosphate fertilizer. Gray or off-white powder (or granules) can be directly used as phosphate fertilizer. It can also be used as an ingredient for compound fertilizers.

1 It can be used as a calcium supplement in shrimp and crab farming.

2. Water quality management can be used to adjust the ratio of nitrogen and phosphorus in water.

3.Buffer: Replenish phosphorus and calcium in the water body, which is conducive to the molting of shrimp and crabs, and is of little use to herring and grass carp.

It is mainly shrimp and crabs that supplement calcium.

It is of little use to herring and grass carp.

It is mainly shrimp and crabs that supplement calcium.

Superphosphate is used at the mouth of the grass herring fish pond, mainly to stabilize the water quality and cultivate excellent algae phase.

Buffer: Supplement phosphorus and calcium in the water body, which is conducive to the molting of shrimp and crabs.

Aquaculture water treatment agents are generally divided into two categories: biological agents and chemical agents. Biologics contain photosynthetic bacteria, nitrifying bacteria, Enterococcus faecalis, etc. Chemical agents include sodium thiosulfate, activated carbon, etc.

You can come and see the production of Lvdayuan.

It can regulate the microecological environment of the digestive system of the breeding object: the beneficial bacteria are strong and thus eliminate the harmful bacteria, and the beneficial bacteria secrete various beneficial enzymes and trace substances, which can significantly improve the immunity of the breeding object, improve the survival rate, promote growth, significantly improve the feed remuneration, and improve the hatching rate.

Purify water quality: reduce floating organic matter, ammonia nitrogen, hydrogen sulfide, nitrate, etc., purify excrement and residual bait in the water body, and adjust the pH value of the water body; The silt is reduced into scattered sand, which significantly increases the amount of dissolved oxygen and reduces the number of water exchange and dredging.

Regulate the microecological environment of the water body: increase the number of beneficial bacteria, make the harmful bacteria and harmful algae lose the living environment, maintain the ecological balance of the aquaculture water, and greatly reduce the incidence of diseases.

Very much, aquaculture to pay attention to the water quality parameters are: dissolved oxygen ammonia nitrogen nitrite residual chlorine hydrogen sulfide water hardness, salt plate alkalinity, according to the right to breed different aquatic products, there are different requirements for water quality, when the parameters deviate to adjust, there are many treatment agents accordingly. According to the method requirements of each person**, there are very many treatment methods and supplies for each parameter.

Dissolved oxygen ammonia nitrogen nitrite residual chlorine hydrogen sulfide water hardness, salinity alkalinity,
