CATDOLL : CATDOLL: Many fish farms use chicken manure to raise fish. How do they do it?

1. Many fish farms use chicken manure to raise fish. How do they do it specifically?

Fresh chicken manure needs to be fully fermented before it can be used to fertilize the water and raise fish. Fermented chicken manure organic fertilizer not only has a good effect on fertilizing the water, but also can prevent fish from being hypoxic due to high temperature caused by natural fermentation. Chicken manure treatment method: Qiangxing composting fermentation agent 1 pack 200 causes water hypoxia, and in an anaerobic environment, a large number of anaerobic harmful bacteria and harmful substances breed, seriously polluting the water quality, such as ammonia nitrogen, nitrite, hydrogen sulfide and other harmful substances. So I think it is necessary to control the excessive degradation of organic matter, so in the water body.

Since chicken manure has high nutritional value, it is often used for pig and sheep farming after certain processing. Of course, it is feasible to use chicken manure for aquaculture, and it is easier to use chicken manure for fish farming than for livestock farming. Although chicken manure has many benefits for fish farming, you must be careful when using it, otherwise it may cause discomfort to the fish. First of all, the chicken manure must be fermented before use. If it is used directly to feed fish, you can mix some probiotics for fermentation.

Fresh feed is better than pig manure feed. Because chicken feed is made of bean cake, corn, etc., it is rich in nutrition. Feeding fish with chicken manure can not only provide high-quality palatable feed for fish, but also fertilize the water and promote the growth of fish. Seal the fermentation. Be careful not to move the bag easily to avoid breaking the bag and causing air leakage. 4. Fermentation is completed. After one to three days of sealed fermentation, there is a fragrance escaping. Be careful not to open the bag casually to check. After opening the bag, it should be tied immediately. After fermentation is completed, it can be processed.

Untreated chicken manure cannot be used to feed fish. After being dehydrated by chicken manure solid-liquid separation equipment, chicken manure can be used directly to feed fish. It is almost odorless and has low viscosity and can be used as fertilizer. The bag must be strictly sealed, airtight and watertight. The top should be slightly raised to prevent water from entering. After fermentation for 3-12 days, the koji fragrance will be produced (depending on the weather and temperature) and it can be used.

Evenly add 20% to 30% wheat or rice bran to the chicken manure, then spread it out in the sun to dry, then sieve to remove impurities, put it in a bag or pile it in a dry place. Because chicken manure contains a large amount of nutrients, high mineral content, and a full range of varieties, using chicken manure to raise fish not only saves commercial feed, but also improves the economic benefits of raising chickens and fish, reduces environmental pollution, and promotes ecological balance.

It is best to deodorize before reuse. You can add 7% of green vitriol (ferrous sulfate) and 3.5% of fly ash to raw chicken manure, dry and mix at 60-80℃, and then remove the stench from the chicken manure. Alternatively, you can use Yifuyuan feces fermentation agent to ferment and deodorize. Pigs, cattle, and fish like to eat deodorized chicken manure, and it can also be used to feed chickens. When using chicken manure to feed livestock and poultry, chicken manure can account for 10%-30% of the feed, and the feeding effect is better if it does not exceed 15%-20%. Fermented chicken manure can be directly put into water fertilizer or processed into fish feed.

When you raise chickens and ducks at home, you can collect their feces and put them in fish farms, where they can serve as fertilizer for the fish.

2. Is it illegal to raise fish by throwing chicken manure into reservoirs?

It is illegal to use chicken manure to raise fish in reservoirs.

It is prohibited to use fertilizers in reservoirs to raise fish, which is stipulated by law. It has caused water pollution and deteriorated water quality, affecting the people's water for production and life. In order to strengthen water quality management, protect the limited reservoir water resources in our county, and control the man-made reservoir water pollution from the source, in accordance with the "Environmental Protection Law of the People's Republic of China", "Water Pollution Prevention and Control Law of the People's Republic of China", "Fisheries Law of the People's Republic of China", "Aquaculture Quality and Safety Management Regulations" and other relevant laws and regulations on "strictly prohibiting the pollution of drinking water sources" and "whoever pollutes shall be responsible for the treatment", the county government has decided to prohibit the use of fertilizers and livestock and poultry manure to raise fish in all small and medium-sized reservoirs in the county after research.

3. What are the benefits of fermenting chicken manure?

Fresh chicken manure is not recommended, and chicken manure for fertilization needs to be fermented before it can be used.

Fermented chicken manure is a fast-acting and long-lasting fertilizer. Because fermented chicken manure has strong fertility, the amount used must be controlled. Please apply fertilizer two weeks before sowing or planting.

What are the advantages of organic fertilizer

The simple answer: soil rich in organic matter, diverse nutrients, and full of life!

3. Improve the utilization rate of fertilizers. Organic fertilizers contain more nutrients but the relative content is low and is released slowly, while chemical fertilizers have a high unit nutrient content, fewer ingredients, and are released quickly. The two are used in a reasonable combination and complement each other. The organic acid produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in the soil and chemical fertilizers. Organic fertilizers and chemical fertilizers promote each other, which is beneficial to crop absorption and improves the utilization rate of fertilizers.

2. Increase yield and improve quality. Organic fertilizers are rich in organic matter and various nutrients, which provide nutrition for crops. After decomposition, organic fertilizers provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate the decomposition of organic matter, and produce active substances that can promote crop growth and improve the quality of agricultural products.

1. Improve soil and improve soil fertility. After organic fertilizers are applied to the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, mature the soil, enhance the soil's ability to retain and supply fertilizers and its buffering capacity, and create good soil conditions for the growth of crops.

There are a lot of nutrients left in chicken manure, with high mineral content and complete varieties. Using chicken manure to raise fish not only saves commercial feed, but also improves the economic benefits of raising chickens and fish, reduces environmental pollution, and promotes ecological balance. Chicken manure is rich in nutrients, including 18.7% crude protein, 2.5% fat, 13% ash, 11% carbohydrates, 7% fiber, 2.34% nitrogen, 2.32% phosphorus, and 0.83% potassium. It is very nutritious, so it is of great practical significance to develop and utilize chicken manure as a new feed or fertilizer resource. However, the traditional method is to directly sprinkle it into the water for use, which is easy to spread infectious bacteria, so it is best to process it, such as after fermentation with Nongsheng-Le-em bacterial liquid, these shortcomings are changed and the nutrition is improved. This method is simple and convenient, and the effect of using it for fish farming after fermentation is good.

Uses of fermented chicken manure

1. It can be used to breed fish and shrimp without polluting the water quality. It can be used as fish and shrimp feed and as a water fertilizer product; 2. It can be used to breed mealworms, maggots, and earthworms to establish an ecological breeding model; 3. It can be used to make biological organic fertilizers for planting, flowers, etc.

2. Fermenting chicken manure as organic fertilizer can enhance the disease resistance of crops. During the fermentation process of organic materials in fertilizer fermentation products, accompanied by a large number of rapid reproduction of microorganisms and a series of complex biochemical reaction processes, microorganisms will produce a large number of special metabolites during the reproduction process (such as enzymes, hormones, antibiotics, these substances are naturally produced by the organisms themselves, not external chemical hormones and antibiotics, only benefits without any toxic side effects), among which hormones can stimulate the rapid growth and development of crops; while antibiotics can significantly inhibit the spread of soil-borne pathogens and improve the disease resistance and stress resistance of crops. Unfermented crude organic fertilizers not only do not have these advantages, but because they carry pathogenic bacteria, they become the main source of infection for the spread of crop diseases. Therefore, these products of fertilizer fermentation agents have good disease resistance after fermentation, which is a good method worth recommending, saving pesticide costs and improving economic benefits.
