CATDOLL : CATDOLL: Can EM bacteria solution be used to culture silver carp?

1. Can EM bacteria solution be used to culture silver carp?

Yes, using Baiyibao em bacterial solution:

① Pretreatment: One week before releasing water, spread EM solid fermentation material into the dry pond, about 30 kg per mu.

② Water treatment: 3-10 days before stocking, sprinkle the water surface with 100 times diluted EM stock solution, about 2-4 kg of EM stock solution per mu (depending on the depth of the fish pond). After that, sprinkle once a month depending on the situation (the amount can be reduced appropriately).

③ Feed processing: ferment the feed with EM (see above for the method), mix the fermented feed into ordinary feed at a ratio of 1-5% and feed it. You can also spray 100 times EM dilution directly on the feed (wetness as the degree) and feed it, or mix the feed evenly with 300 times dilution and feed it.

⑶ Feces treatment: EM bacteria fermentation liquid is fermented at a ratio of 1: feces 50 and then added into the water body.

⑷Fish disease prevention and control: When fish float to the surface or overflow the pond, use 2 kg of EM bacterial solution per acre to make a diluted solution and sprinkle it evenly on the water surface, and sprinkle it again after 2 days.

2. Is it better to use EM bacteria to raise fish on rainy days or sunny days?

Generally, it is best to use it on a sunny day, preferably in the morning.

1. If the fermented feces fertilizer plays a role in improving water quality, the fish pond should be stocked with filter-feeding fish, mainly silver carp and bighead carp, which can account for about 70% of the stocking amount. Some omnivorous fish such as tilapia, carp and crucian carp can be appropriately matched.

2. If the fermented feces are made into granular feed and then sprayed with Nong Sheng Le aquatic bacteria liquid and put into the fish pond, it is advisable to release grazing fish, mainly grass carp and bream, which account for about 50% of the input, and then mix it with other fish.

3. On rainy days, the photosynthesis of phytoplankton in the water is poor, and it is not easy to decompose the effective components in the fermented feces. Generally, fertilizer should be applied in the morning on sunny days to avoid wasting labor and fertilizer.

4. The fermented feces newly taken out of the pond should be piled outside for 1-2 days to release gases that are harmful to fish growth.

5. If the fish farm uses fermented manure to raise fish, the design of the pond should take into account the gas production effect and the need for regular fertilizer use in the fish pond. A fermentation tank with middle-layer feeding and bottom-layer semi-automatic discharge is preferred.

How to use Nongshengle aquatic bacteria liquid in aquaculture

1. Spraying feed

1. Direct feeding

Spray Nongshengle Aquatic EM bacteria liquid directly on the feed at 0.2% of the feed amount, stir evenly while spraying, and then feed it directly.

2. Feeding after secondary fermentation of aquatic bacterial liquid

Add Nongshengle Aquatic EM bacteria liquid and an equal amount of brown sugar to 0.2% of the feed amount, then dilute the bacteria liquid and brown sugar 10-20 times with water, put them into plastic barrels or tanks, seal and ferment for 2-3 days (ambient temperature is 30-35℃), then spray the feed and feed. Practice has shown that the effect of mixing the bacteria liquid with the feed after secondary fermentation is better than mixing it with the feed directly for feeding.

3. Notes

○1 The secondary fermentation solution should be used up within 3 days.

○2 The feed mixed with bacteria should be fed immediately. If it cannot be finished at one time, the remaining feed should be sealed and stored. The validity period is one week in summer and one month in winter.

2. Pond Splashing

1. Function

Increase the amount of dissolved oxygen in the water and enhance the photosynthetic effect; improve water quality, eliminate harmful bacteria, enhance immunity, reduce the incidence of disease and reduce losses; improve product quality, growth efficiency, breeding rate and growth efficiency; reduce the use of drugs and produce organic food; have a good preventive effect on fish floating heads and pond flooding;

2. Usage

○1 Three days before stocking the fish, use 5-8 kg of Nongshengle aquatic bacteria liquid per acre of water surface, dilute it 50 times and spray it throughout the pond.

○2 After stocking, use 1 kg of Nongshengle EM bacterial solution per mu for 10 consecutive days, and then spray it 2 to 3 times a month depending on the water quality.

3. Disease prevention and treatment

When fish have bacterial enteritis, printing disease, gill rot, etc., you can soak the diseased fish in 100-150 times high concentration Nong Sheng Le EM bacterial solution, or apply 10-50 times high concentration Nong Sheng Le EM bacterial solution directly to the diseased area. It usually takes 3-5 days to heal.

4. Preservation of aquatic products

For the aquatic product preservation tank, spraying 500 times diluted Nong Sheng Le Aquatic EM bacteria liquid once every 1 to 2 days can extend the shelf life of aquatic products and keep the surface of aquatic products smooth and pleasing.

3. What role does aquatic em bacteria play in aquaculture?

EM bacteria is a new type of composite microecological preparation, which is a brown translucent liquid with a pH value between 3.5 and 4.5. It is made from a composite culture of photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, acetobacter and other microorganisms.

The main functions are: promoting animal growth, improving feed utilization, enhancing the body's disease resistance, removing feces odor, and improving the ecological environment.

4. Please tell me about EM bacteria. . . .

As far as I know, EM bacteria is a kind of mixed bacteria, generally including 80 kinds of beneficial microorganisms from 10 genera in seven categories of microorganisms, including photobacteria, lactic acid bacteria, yeast, bacillus, acetic acid bacteria, bifidobacterium, and actinomycetes. It is not known whether it contains nitrifying bacteria. But it is certain that pure nitrifying bacteria cannot be called EM bacteria.

5. How to use em bacteria

em bacteria need to be used correctly in the fish tank to achieve the maximum effect.

My usage is like this:

1. The use of em bacteria requires the use of filtration equipment, as shown in the following figure

Necessary filter materials need to be added to this filter box to facilitate the growth of beneficial bacteria in EM bacteria.

2. Bacteria house is necessary. The bacteria house I choose is a ceramic tube as shown below. It is small and porous. It is mainly to lay a layer at the bottom of the filter box and put some at the bottom of the fish tank (not necessarily need to lay a layer)

In the filter material box, a layer of filter material needs to be laid on the ceramic tube. I chose a better three-layer filter material (mainly to filter some impurities such as fish feces, after all, the digestion capacity of bacteria is also limited)

3. When all these are ready, you can start the tank. Starting the tank is very simple. First, fill the fish tank with water, and then let it sit for two days, mainly to remove the chlorine in the water. After that, the key is that the Yi Fu Yuan EM bacteria is not poured directly into the fish tank, but after adding a small amount of water to the EM bacteria liquid, it is evenly sprinkled into the filter box, and the upper filter is turned on to let the water in the fish tank flow through the upper filter. This process is to allow the EM bacteria to take root and reproduce in the filter box first. After the EM bacteria and the upper filter equipment start working for 24 hours, the fish that need to be raised can be put in and fed normally. The EM bacteria I chose is the Yi Fu Yuan EM concentrate because it is easy to use.

4. When feeding fish, you can also add EM bacteria (beneficial bacteria survive better in the fish's stomach, which can make the fish eat more actively and digest more thoroughly, and at the same time enhance the fish's resistance). The method is to put the fish food to be fed in a small cup, pour in 1/3 diluted Yifuyuan EM bacteria stock solution, stir and let it stand for 20 minutes, and feed the fish food after the fish food absorbs the EM bacteria solution. Note that when feeding fish food, please close the upper filter, and open it again as needed after the fish has finished eating. Generally, I open it every night at the beginning. After that, I open it every few nights.

5. After a month, the basic microecology of the fish tank is formed. After that, oxygenation and top filtration are necessary. The filter material in the filter box only needs to clean the top white layer of the three layers of filter material, and the others do not need to be cleaned. There is no need to change the water at all. However, even if there is no need to change the water, I will regularly draw out some water from the bottom of the fish tank, because this water is very suitable for watering flowers. While cleaning the fish feces at the bottom that have not been sucked away by the top filter, it can also bring the EM bacteria and nitrates that have survived and reproduced in the water to the soil of the plants, which is really killing two birds with one stone. After pumping out the water, new water needs to be added. The newly added water must be left to stand for a few days to dechlorinate. When adding new water, the fish food fed that day can be processed by EM bacteria to increase the balanced number of EM bacteria in the water.
