What is the use of sprinkling brown sugar in fish fry ponds?

Fish pond fish farming is an important part of China's aquaculture industry, and in its breeding process, the stocking work of seedlings is very important, including stocking density, stocking treatment, etc. So how many fry are put in an acre of fish pond? What are the preparations before seedling?

The details are as follows: How many fry are put in an acre of fish pond?

Generally, it is more appropriate to put no more than 1,000 fish fry in one acre of fish pond, such as 400-850. However, it also depends on the influencing factors such as the size of the fingerling, the stocking pattern and the size of the fish pond, so the number of fry is uncertain, and it is necessary to pay attention to the reasonableness.

What are the preparations before seedling?

1.Fish pond clear pond.

After fishing in autumn and winter, the pond water is drained to remove silt, weeds and wild fish in the pond. The silt around the pond is stacked on the slope of the pond, thickened, widened and leveled the bottom of the pond.

2.Disinfect thoroughly.

Use drugs to clean the pond and disinfect it, and kill all the wild trash fish, pathogens and predators that have an impact on the fish in the fish pond. Commonly used Qingtang drugs are croton, rotenin and quicklime.

3.Cultivating fertilizer water.

If it is a new pond, due to the lack of various nutrients, the number and frequency of use of base fertilizer are higher than that of the old pond, and organic fertilizer + compound fertilizer + EM bacteria can be used to cultivate fertilizer water.

4.Fingerling selection.

According to the local climatic conditions, bait, fertilizer source, etc., choose the best fish species suitable for the local area. If the fry are transported over long distances, it is best to put them in a fry box for temporary rearing before restocking. At the same time, the fish fingerlings should also be disinfected, and the fish body can be soaked in a certain concentration of salt water or medicinal solution to kill the germs and parasites parasitic on the fish body.

Brown sugar cannot directly serve as a fertilizer or water, but it can be used to activate or cultivate beneficial flora, such as yeast, lactic acid bacteria, etc.

The role of brown sugar in aquaculture.

1. Glucose can be used for the emergency synthesis of ATP in the state of stress, improve the non-specific resistance of the body, that is, improve the ability to resist stress, and effectively alleviate the stress response of the fish body during the fishing process.

2. Glucose can play a role in detoxification and detoxification, and effectively enhance the disease resistance and immunity of the fish body.

3. Effectively supplement the carbon source and energy required for the growth of the body, promote metabolism, and improve the survival rate of transportation.

4. With the splashing of biological agents, it can speed up the improvement of water quality and alleviate the deterioration of pond water quality caused by fishing.

5. **Fish debonding, bleeding and scaling and other diseases.

Brown sugar cannot play the role of fertilizer and water, and it needs to be fermented with bacteria before it can be used to fertilizer water. Such as: super EM strains.

1 bottle of strain + 4 kg of brown sugar + 80 kg of water + closed fermentation for 24 hours = 84 kg of stock solution;

1. When putting seedlings in the pond: soak the fry for 15 minutes with 30ml of activated bacterial solution mixed with 10kg of water; 3-5 days before seedling, 2kg of activated bacterial solution should be sprinkled on the whole pool of each mu of water, and it should be used once every 15 days or so;

2. Splashing the whole pool: 1kg of activated bacterial solution is used per mu of water, which can be used twice in a row, and it can be used every 10 days or so in the middle and late stages of breeding, and the dosage can be increased to 2kg mu as appropriate;

3. Mixing feeding: 100kg feed uses activated bacterial solution, 2 times a day, for 3-5 days.

It is generally used externally, splashed. If the water quality in the pool is fertile, the algae are vigorous, and the pH value usually fluctuates greatly, by applying baking soda or sugar, flour, etc., carbon dioxide can be appropriately supplemented, which can prevent algae from falling and the pH value is too high, which is conducive to stabilizing the water quality and preventing or slowing down the occurrence of stress reaction.

If the water quality in the pond is not good, too fat, and the pH value exceeds the standard, you can add some brown sugar appropriately to promote the generation of carbon, stabilize the water quality, and prevent the occurrence of the problem of the stress source of the bath.

Brown sugar has no effect on crab farming.

Crab farming essentials:

1.Detoxification: reduce or eliminate the toxicity of drug residues and heavy metal substances (copper sulfate, etc.) in Qingtang, and eliminate the impact of toxic substances on crab seedlings. Such as crab seedlings crawling nets, going ashore and even dying.

Main measures: 1) Use antidotes to eliminate drug residues and the toxicity of heavy metals in water bodies.

2) The whole pond is sprinkled with Baijiling (10 acres of bags) to improve the physique and anti-stress ability of crab seedlings.

2.Fertilizer water: In the process of river crab breeding, the water body is required to maintain a certain degree of fertility, and crabs cannot be raised in lean water, which is very important to improve the yield and its market specifications.

In the early stage of breeding, fertile water can cultivate the natural bait of river crabs, improve the photosynthesis ability of the water body, and provide sufficient dissolved oxygen for the water body. At the same time, it can also promote the growth of aquatic weeds and prevent the occurrence of moss.

Main measures: 1) Nuobiqing biological water purification agent (20 acres of bags) + Bilude (10 acres of bags) + organic fertilizer poured in the whole pool, and then used again after 10 days depending on the situation.

2) Youcaile (4 acres of bags) + Bilude (10 acres of bags) + organic fertilizer poured in the whole pool, depending on the situation, 10 days after the use of another time.

3.Grass planting: aquatic plants play an important role in the process of river crab breeding, first of all, aquatic plants are indispensable for maintaining the ecological balance of the whole water body, which can not only release oxygen through photosynthesis, but also absorb organic substances in the water body to purify water quality.

Secondly, aquatic weeds can be used as bait and habitat for river crabs, and play a role in regulating water temperature during the high temperature season.

Main measures: 1) Fertilization: must be green (10 acres of bags) + organic fertilizer or granular fertilizer.

2) Keep the aquatic plants fresh: Use Nuobiqing biological water purifier (10 acres bag) to keep the aquatic plants fresh.

4.Snail stocking: snail feeding is an important part of ecological breeding of river crabs, snails can not only provide fresh animal bait for river crabs, but also can ingest organic particles in the pond, filter feed plankton, and play a role in cleaning the water body.

Main measures: depending on the water quality of the pond, the method of batch delivery is adopted, generally 300 500 catties per mu is appropriate, and the water quality is too thin. Affect the shelling and growth of river crabs.

1. If the water quality in the pond is not good, too fat, and the pH value exceeds the standard, you can add some brown sugar appropriately to promote the generation of carbon, stabilize the water quality, and prevent the occurrence of bath stress.

2. It can maintain the normal growth of beneficial microorganisms in water, control harmful substances such as ammonia nitrogen and hydrogen sulfide, and maintain a balanced ecological structure.

3. After the crab eats brown sugar, it supplements the carbon source and energy required by the body, promotes metabolism, increases the resistance of aquatic animals, and prevents the occurrence of diseases.

4. It can replace the function of detoxification of some drugs, reduce the occurrence of pathogenic bacteria, and make breeding safer.

5. In the process of aquaculture, when photosynthetic bacteria are used, adding some brown sugar can activate the bacteria faster and play a greater role.

There is a supplementary water body to supplement the carbon source.

Supplementing the carbon source of the water body not only supplements the nutrients needed by the aquatic plants, but also supplements the nutrients of the water body, which is still good. I suggest that you divide it into two parts, one is the input of amino acids, the other is brown sugar, if you have the conditions, you can buy molasses, because the input of molasses is very low, and it is also a very good choice.

Summary. Third, it is used together with phosphate-solubilizing bacteria and brown sugar to increase the utilization rate of phosphorus.

Third, it is used together with phosphate-solubilizing bacteria and brown sugar to increase the utilization rate of phosphorus.

The most commonly used phosphorus cultivation Shenlu fertilizer in aquaculture is superphosphate, but it has poor water solubility and low utilization rate, so how to increase the utilization rate of calcium phosphateFirst of all, soak the phosphate fertilizer overnight before use, and then splash it in the morning on a continuous sunny day without wind, and do not open the aerator after use, the longer the phosphate fertilizer stays in the water body, the higher the utilization rate.

Of course, red ponds are the best skin care products for women. Brown sugar, also known as red sugar and purple sugar, is coarsely refined sucrose. It has a sweet taste and a special aroma of sugar cane, which can be used to color meat dishes.

Nutritional efficacy: Although brown sugar has more impurities, it retains nutrients well, and in addition to sucrose, it also contains a small amount of iron, calcium, carotene and other substances. It releases energy quickly, has high nutrient absorption and utilization, and is believed by traditional Chinese medicine to strengthen the spleen and warm the stomach.

The effect of invigorating blood and dissipating cold. Brown sugar can effectively relieve women's dysmenorrhea caused by cold and body weakness. It also contains the ingredient "motherwort", which can promote uterine contractions and discharge the uterine cavity after childbirth.

In addition, brown sugar can play a certain auxiliary role in arteriosclerosis, and is not easy to induce dental diseases such as dental caries.

Eat in a good way: about 30 grams per day. Excessive consumption can affect appetite and digestion and absorption in the gastrointestinal tract.

It is advisable for pregnant women to take it for 7 to 10 days after giving birth. People with cold and abdominal pain can use brown sugar ginger soup to dispel the cold. Patients with diabetes and high blood sugar should not consume it.

Brown sugar should not be drunk with milk. Brown sugar is easy to breed bacteria during storage, so brown sugar water should be boiled and drunk, not boiled water.

Selected Collection: High-quality brown sugar is dark red in color, bright in color, no impurities, no mildew, and has a strong sweet taste. Brown sugar easily absorbs odors and should not be placed together with condiments with strong odors, and should be packed in glass or ceramic containers.

Store in a cool, dry place. The shelf life is generally 18 months. Brown sugar is not highly refined, retains more vitamins and minerals, per 100 grams of brown sugar contains 90 mg of calcium, 4 mg of iron, about 3 times that of white sugar and brown sugar, and also contains a small amount of riboflavin (vitamin B2) and carotene.

According to the Compendium of Materia Medica, brown sugar has the effect of dissolving blood stasis, dissipating cold and invigorating blood, warming the stomach and strengthening the spleen, and relieving pain. In China, there is a custom of mothers eating brown sugar and women drinking brown sugar water to replenish blood during menstruation. In addition, if you are cold or wet in the rain, drink a bowl of ginger brown sugar water to prevent colds.

This may have something to do with the abundance of minerals in brown sugar, especially iron. Iron in traditional Chinese diet is better than plant food, poor absorption and utilization, and the incidence of anemia in women, especially pregnant women, is high, and the iron in brown sugar is undoubtedly a good supplement, which is especially important in the era when animal food is not abundant. Nowadays, animal foods that are high in iron in the diet are abundant, and it is no longer so important to drink brown sugar water.

Habitual practice, willing to drink brown sugar water, can relieve abdominal pain and enhance physical fitness. It can also raise blood pressure. If your blood pressure is low, drinking brown sugar water can help.

Brown sugar replenishes blood, and patients with anemia should drink more.

It is used when making sugar rolls.
