All fish farmers know that our fish pond is a complex ecosystem. There is sunshine and air above the water surface; There are terrestrial plants on the pond foundation; Water includes fish, various aquatic plants, insects, fleas, algae, fungi, bacteria, viruses, organic matter and inorganic salts. There is silt at the bottom of the pool, and the organisms, organic matters and inorganic salts on it also grow. There is an extremely complicated relationship of mutual nourishment, mutual help and mutual restriction between them. Ecological farming is to make rational use of their relationship to produce the aquatic products we need. Rational use of their relationship, whether from the economic benefits, social benefits or environmental benefits, can achieve the best results, which is ecological farming.

Second, what is green and pollution-free aquatic products?

First of all, the breeding base must be certified, and the most important thing is that the atmosphere, soil and water quality must meet the requirements of the national standard of "Safety and Quality of Agricultural Products-Environmental Requirements of Aquatic Products Origin" and the standard of the Ministry of Agriculture of "Freshwater Aquaculture Quality of Pollution-free Food"; Secondly, aquaculture must be carried out in accordance with the technical operating rules for the production of pollution-free aquatic products, from the stocking of fry to the use of all inputs such as feed, fertilizer and fishery medicine, to the fishing, storage and transportation, quality inspection, bagging and listing of products, and all links must meet the requirements of relevant standards or norms; Third, products must be sampled and tested by authoritative quality inspection institutions designated by the government, and they can only enter the market after they are completely qualified and certified.

What is the significance of aquaculture?

1, environmental benefits: the traditional farming mode not only consumes a lot of water, but also uses a large number of drugs prohibited by the state, such as copper sulfate, malachite green, trichlorfon and furan drugs. A large number of water changes have caused great damage to the environment. At the same time, it also caused immeasurable damage to the bottom of the fish pond, greatly destroyed the ecological environment of the fish pond, and led to a large number of malignant pathogenic microorganisms multiplying. Aquatic products spread through the food chain, which not only harms people's health, but also destroys the environment.

2. Social benefits: With the improvement of people's living standards, people's awareness of environmental protection has been strengthened, and more attention has been paid to food safety. In addition, with China's accession to the WTO, aquatic products must meet the food safety standards of other countries. Therefore, for the health of people in China and the high profit of aquatic products export in China, ecological farming must be implemented.

3. Economic benefits: The traditional farming mode has caused a serious imbalance of microbial flora in fish ponds, a large number of pathogenic microorganisms have increased, and drug resistance has increased, so fish farmers have to increase the dosage of drugs. As a result, fish diseases have not healed, fish bodies have been injured, the yield has dropped sharply, the quality has declined, the cost has increased, and flooding incidents have occurred frequently. This is the main reason why the conventional fish farmers in Datong Lake and its surrounding areas give up fish farming and the phenomenon of cotton planting in fish ponds appears. Fish farmers in Hubei took the lead in applying the ecological farming method of microbial agents and produced gratifying results. The grass carp they produced occupied Yueyang fresh fish market in Hunan and some other fresh fish markets in Hunan with the absolute advantage of 1 yuan lower than ours per kilogram. In the cultivation of Monopterus albus, it is also soaked with drugs, which seriously affects the growth and product quality of Monopterus albus and makes the cultivation cost high. What's more, the overwintering Monopterus albus died in the box, which sounded the alarm for us not to carry out ecological farming. We farmers must change our production concept! Get out of the strange circle of traditional farming mode.

Fourth, advocate the feasibility of ecological farming.

With the progress of aquatic science in China, the systematic technology of ecological aquaculture has been developed and scientific standards have been formulated. At the same time, we also developed high-efficiency, low-residue, low-dose aquatic drugs suitable for ecological farming, especially Chinese patent medicines and traditional Chinese medicine extracts, and Tianyi EM, a beneficial microbial preparation for animal strength feed additives produced by Shenzhen Xikean Company. It is also a full guarantee for us to carry out ecological farming. The case of grass carp yield exceeding one and a half tons per mu in Guangdong can also be used as evidence of the feasibility of ecological farming.

Five, how to implement ecological farming

Ecological farming covers a wide range, mainly including the following categories. (a) artificial ecological environment feeding method. (2) Multi-variety stereoscopic cultivation method. (3) Open-flow or micro-flow culture. (4) closed circulating water industrial culture method. (5) The mutually beneficial aquaculture of aquatic products and crops. (six) the use of microbial preparation culture method. Limited by space, I can't explain them one by one here, so I will focus on the use of microbial agents. If you are interested in the first five methods, please consult our department. What is the method of microbial preparation culture? In recent 10 years, viable microbial preparations have been gradually applied and popularized in aquaculture, which has provided a strong guarantee for pollution-free and healthy aquaculture production. At present, the commonly used products are photosynthetic bacteria preparation, Bacillus, lactic acid bacteria preparation, Tianyi EM raw dew and so on. They can decompose organic substances such as bait and fish manure left in the water, reduce the ammonia nitrogen content in the water, make the aquaculture water clean, and thus improve the environment; They can improve the gastrointestinal environment of breeding objects, enhance appetite, promote growth and improve feed reward; They can also enhance the immune function of cultured objects, improve immunity and enhance disease resistance; It can also strengthen beneficial bacteria and prevent and reduce the occurrence and spread of bacterial diseases.

First, what is aquatic ecological farming?

Fish friends all know that our fish pond is a complex ecosystem. The sun is above the water and air; Children have terrestrial plants; Water is fish, various aquatic plants, insects, fleas, algae, fungi, bacteria, viruses and organic and inorganic salts. These organisms and organic and inorganic salts also grow at the bottom of the mud. There is an extremely complicated relationship between them, and ecological farming is to make rational use of their relationship with each other to produce the aquatic products we need. Rational use of the relationship between them, whether from the economic benefits or social benefits and environmental benefits as a whole, can achieve the best results, which is ecological culture.

Second, what is green and pollution-free aquatic products?

First of all, the breeding base should be certified, and the most important thing is that the atmosphere, soil and water quality must meet the requirements of "quality and safety of agricultural products-environmental requirements of aquatic products origin", national standards and "water quality of pollution-free freshwater aquaculture products" standards of the Ministry of Agriculture; Secondly, pollution-free aquatic products should be cultured in accordance with the production technical regulations, from fry stocking to the use of all inputs such as feed, fertilizer and medicine, to product fishing, storage and transportation, quality inspection, bagging and listing, etc., all links must meet relevant standards or norms; Third, products must be inspected by authoritative sampling inspection institutions designated by the government, fully qualified and licensed before they can enter the market for sale.

Third, what is the significance of aquatic ecological farming?

1, environmental benefits: the traditional culture mode not only has a large amount of water, but also the application of large doses of substances prohibited by the state, such as copper, malachite green, trichlorfon, furan and other drugs, and a large amount of water, which has caused great damage to the harsh habitat. At the same time, it has caused immeasurable damage, and the ecological environment in the fish pond has been greatly destroyed, and a large number of pathogenic microorganisms have multiplied viciously. The aquatic products spread through the food chain, which not only does harm to human health, but also does great damage to the environment.

2, social benefits: With the improvement of people's lives, people's awareness of environmental protection has been strengthened, and people pay more attention to food safety. Coupled with China's accession to the WTO, aquatic products must meet the food safety standards of other countries in order to enter the international market. Therefore, for the sake of people's health and the high profits of China's export of aquatic products, they must implement ecological farming.

3. High performance-to-price ratio: The traditional farming method has caused a serious imbalance of microbial flora in fish ponds. Pathogenic microorganisms are swallowed up by macrophages, and their resistance is enhanced. As a result, fish farmers have to increase the dosage of drugs. As a result, fish bodies are injured, the output is sharply reduced, the quality is reduced, and the cost is increased. Pan Tong often occurs. This is because the conventional fish farmers in our Datong Lake and surrounding areas give up fish. It is strange that the fish pond is mainly caused by how much cotton is produced. Fish farmers in Hubei took the lead in applying the ecological farming method of microbial agents, and achieved gratifying results. They produced grass carp with an absolute advantage of less than I per kilogram 1 yuan, occupying the fish market in Yueyang, Hunan Province and the fresh fish market in other parts of Hunan Province. Soaking medicine was also used in the culture of Monopterus albus, which seriously affected the growth and product quality of Monopterus albus and made the culture cost high. To make matters worse, the eel boxes in winter have become my death hole, and they have not sounded the alarm for our ecological farming. Fish farmers must change our production concept! Break away from the traditional reproductive cycle model.

Fourthly, the feasibility of promoting ecological agriculture.

With the progress of aquatic science in China, systematic technology suitable for ecological farming has been developed, and scientific standards have been formulated. Fishery drugs with high efficiency, low residue and low dosage have also been developed for ecological farming, especially traditional Chinese medicines and extracts of traditional Chinese medicines, as well as beneficial microbial preparations, and vitality, a nourishing animal feed additive produced in em Providence and Shenzhen, has been revealed. Its ecological agriculture has been fully protected. There is already an example of grass carp yield of half a ton per mu in Guangdong, which can also be used as evidence of the feasibility of ecological farming.

Fifth, how to implement ecological agriculture.

Ecological agriculture covers a wide range, and it has the following main aspects. (A) the ecological environment of artificial breeding method. (2) Three-dimensional multi-variety breeding method. (c) Open water or water micro-culture method. (d) The method of circulating water in closed factory farms. (5) Crop breeding methods of aquatic symbiosis and mutual benefit. (6) A preparation method using microbial culture. Due to the limitation of space, I can't talk about 1 1 here. We mainly use microbial agents to illustrate this method. If you are interested in the first five methods, please consult me. What is the propagation method of microbial agents? 10 Over the past few years, microorganisms have been gradually applied in aquaculture, which has promoted this healthy aquaculture and provided a strong guarantee for pollution-free production. At present, more products are prepared by photosynthetic bacteria, Bacillus and lactic acid bacteria, such as the original em revealed by providence. They can decompose organic substances such as bait and fish manure left in the water, reduce the ammonia content in the water, make the aquaculture water clean and improve the environment; They can improve the breeding environment of gastrointestinal tract, enhance appetite, promote growth and improve feed reward; They can enhance the immune function, immunity and disease resistance of the target culture; It can strengthen beneficial bacteria and prevent and reduce the occurrence and spread of bacterial diseases.
