CATDOLL : CATDOLL: When the water quality in aquaculture is polluted, what kind of water purification can be used to keep the water color stable for a long time?

If you want to know more about Qifu Aquatic EM bacteria, please contact me

Aquatic experts explain the usage of EM bacteria:

Taking pond fish farming as an example, water purification is required first. One day before stocking, 100 times diluted EM solution is sprinkled on the water surface. Then, it is sprinkled once every 15 days. The frequency of sprinkles is adjusted according to the water quality. Sprinkling is most effective when it rains. EM solution is used per acre.

1 kg. You can use 200 times diluted EM bacteria solution to treat fish feed, such as spraying it on granular feed until it is wet, and use it immediately after spraying.

The precautions for use are as follows: EM bacterial liquid is a brown translucent liquid with a sour taste and a slightly sweet aroma. It must be noted that there is an odor when the bottle is first opened. If the bottom of the container is slightly turbid and there is a small amount of white substance floating on the top, it is normal. After use, the bottle cap should be closed immediately to keep it sealed.

EM bacterial solution should be stored in a cool place away from light. The suitable temperature is 5℃~45℃. If the temperature exceeds this, the vitality of some bacterial strains will be affected, and the dosage should be increased appropriately.

The main effects of aquatic em bacteria liquid:

1. Enhance the immune and disease resistance of fish, shrimp, crab and sea cucumber, and reduce the incidence of diseases such as red skin, rotten gills, hard scales, skin ulcers, poor nutritional metabolism, slow growth, and weakness in aquatic animals;

2. Rapidly degrade harmful substances in water bodies, reduce nitrite, hydrogen sulfide, ammonia nitrogen content, and regulate water quality;

3. Reduce the mortality rate of fresh aquatic products during transportation, and have a special effect on preventing the death of fry and larvae during transportation, thus extending the freshness period of aquatic products;

4. Reduce the residual harmful substances in feed and aquatic animals and improve the quality of aquatic products;

5. Improve feed conversion rate and reduce feeding costs.

6. Inhibit the growth and reproduction of harmful algae and fungi, promote the reproduction of beneficial unicellular algae, and maintain the microecological balance of water bodies;

7. Stabilize water quality, prevent water aging, increase dissolved oxygen content in aquaculture water, and increase aquaculture density.

Water quality control

Take 10 mu of water surface as an example: dilute 10 kg of Qifu Aquatic Bacteria Liquid with water 50 times, and evenly sprinkle it on the water surface. You can also mix the bacteria liquid and bait evenly according to the above ratio when putting bait, and then put them together. The usage cycle is generally 2-3 times a month. It is usually put in the morning on sunny days.

Bait fermentation

Commonly used fermentable materials include: various types of dregs, straw, grass powder, vegetable cakes, animal feces, scraps, etc., and materials can be obtained according to local materials. 1 kg of Qifu Aquatic Bacteria Liquid can ferment 200 kg of bait (calculated by dry weight).

The fermentation method is: dilute the Qi Fu aquatic bacteria liquid 100 times with water (that is, add 100 kg of water), and then evenly mix it with the bait to be fermented, adjust the moisture to about 60%, and then seal and start fermentation. The fermentation time is generally 2-5 days.

The method to judge the humidity is: grab a handful of material with your hand, hold it tightly, you will see water stains between your fingers, but no water will drip, stand up, loosen your hands, and the material ball will fall to the ground and then disperse.

Mixing feed and feeding

If you want to mix Qifu aquatic bacteria liquid into the bait for feeding, you can add Qifu aquatic bacteria liquid at 0.5% of the weight of the feed. The specific method is as follows:

To prepare 100 kg of feed, take 0.5 kg of Qi Fu bacteria liquid and add about 20 kg of water to dilute it. Stir the bait while spraying the diluted Qi Fu aquatic bacteria liquid. After mixing evenly, you can feed it.

Benefits and effects: Producing bioactive substances can reduce feed conversion, enhance the absorption function and disease prevention and stress resistance of aquatic animals, promote growth, significantly reduce the amount of medicine, improve water quality, make the water clear, not rotten or smelly, and reach a visibility of 25-50 cm, and the water change time can be extended by more than 2 times. Full-time use can significantly reduce drug costs by more than 80%. Adhering to the use of Qifu aquatic bacterial liquid throughout the process can significantly increase the survival rate by nearly 30% and increase the efficiency by 20-35% (white shrimp weight gain 15%-60%; freshwater fish average weight gain 10%-30%), and increase the spawning rate by 20-35%. The breeding cycle of the same environment can be put on the market 10-20 days earlier, with obvious comprehensive benefits and a large increase.

Fermented organic fertilizer

Common fermentation materials include: various animal feces, plant stems and leaves, straw, grass powder, etc. Organic fertilizer can proliferate beneficial bacteria through fermentation, promote the reproduction of zooplankton, and avoid water pollution. The fermentation method is the same as the above-mentioned "bait fermentation" method. It is worth noting that if more animal feces are used, the dosage per mu should be 100-150 kg, not too much.

Mainly aimed at aquaculture sites such as large lakes and reservoirs.

(1) Pre-stocking treatment: Dilute the Qi Fu aquatic bacteria liquid 50 times and directly spray it on the spawning grounds of ferocious fish or wild fish to destroy their breeding and growth environment and control their population size.

(2) Feed with Qi Fu Aquatic Bacteria Liquid Fermented Feed. For the fermentation method, please refer to the above-mentioned "Bait Fermentation" column.

(3) Soak a honeycomb-shaped object such as a sponge in a diluted solution (about 10 times) of the Qi Fu Aquatic Bacteria Liquid for 24 hours, and then hang it in the middle of the net cage. The Qi Fu Aquatic Bacteria Liquid will continue to spread through the movement of the fish. The Qi Fu Aquatic Bacteria Liquid hanging object should be replaced once every 7 days, which can completely change the water environment of the net cage.

(4) Use Qifu aquatic bacteria liquid, fermented material, and yellow mud in a ratio of 1:2:4 to make very sticky lumps, weighing 1 to 1.5 kilograms each. After drying, hang bags or baskets near the bait to provide a fixed residence for the beneficial bacteria in Qifu aquatic bacteria liquid and enhance the purification effect, thereby improving and stabilizing the water quality. This lumps should be replaced once a month. 10 to 15 lumps should be placed per mu.

After Qi Fu aquatic bacteria liquid penetrates into the water body, its group action can kill or inhibit pathogenic microorganisms and harmful substances, adjust the breeding environment, increase the dissolved oxygen (oxygen) in the water, promote the activation and growth of normal bacteria and beneficial algae in the breeding ecosystem, and maintain the ecological balance of the breeding water body; mixing it into bait for feeding can directly enhance the absorption function and disease resistance of aquatic animals and promote healthy growth.

The photosynthetic bacteria in Qi Fu Aquatic Bacteria Liquid can also utilize hydrogen sulfide, organic acids, and ammonia in the water to remove ammonium nitrite in the water through denitrification, thereby purifying the excrement and leftover bait pollution in the breeding pond, improving water quality, and reducing diseases.

The main functions of Qifu Aquatic Bacteria Liquid are:

1. Reduce pathogenic microorganisms and unhealthy algae; significantly enhance the immunity and disease resistance of the aquacultured objects, reduce the incidence of disease, and improve the survival rate. Users reported that Qifu Aquatic Bacteria Liquid can nearly double the survival rate of crab seedlings, and increase the survival rate of Chinese grouper from the original 30% to more than 70%.

2. Increase the number of beneficial microorganisms. The number of zooplankton and beneficial algae on the water surface increases, especially the number of red worms, which continue to increase and cover the water surface.

3. Stabilize and improve water quality. The water is clear in color, not smelly or rotten, and has no odor such as hydrogen sulfide and ammonia. The visibility is at 25 to 50 cm for a long time and is relatively stable. The water change time can be extended by more than 2 times.

4. Fish and shrimp feces, impurities and waste materials at the bottom of the pond will not turn into silt but appear as loose sand.

5. Promote growth and significantly increase the weight gain rate. Practice has proved that under the same environment, after using Qifu aquatic bacterial liquid, the turtles can be put on the market 10 to 15 days earlier, the average per mu yield will increase by 20% to 35%, the egg laying volume will increase by 25%, and the egg laying time will be extended. Some experiments have shown that after using Qifu aquatic bacterial liquid in a normal temperature new turtle pond, the egg laying time is extended by nearly 70 days, and the hatching rate is better; the bait is not smelly, which improves the breeding environment.

Real large-scale or professional farmers will choose high-quality microecological preparations to use and achieve considerable benefits and reduce costs and risks. A good product will always create benefits for customers, and will not become a cost for customers. On the contrary, choosing low-priced or diluted products may seem more economical, but in fact, you are the one who suffers the most. As long as you insist on using good products for 1 to 3 months, you will find that the farming benefits are significantly different.

Qi Fu Company was established in 2005 and is one of the earliest companies in China to engage in the research and development and production of EM bacteria fermentation agents. Over the past 9 years, the company has always led the industry with its absolute product technology advantages and extensive market customer share.

At present, the products produced by Qifu Company include fermentation bed pig breeding strains (bacterial liquid), breeding strains (bacterial liquid), planting strains (bacterial liquid), aquatic strains (bacterial liquid), deodorizing disinfectant, feces fermentation strains (feces decomposers), microbial growth promoters, etc. At the same time, the company produces general preparations such as EM strains and EM bacterial liquid to meet customers' needs for diverse uses of products.

You can use the Guanbionlong bioreactor, which is stable and efficient in the long term, and can effectively decompose pond feces, feed residues and other debris, and excrete ammonia nitrogen.

It can also reduce breeding costs and improve breeding efficiency. It can be used for about 4 years and release probiotics into the breeding pond.
