First, artificial ecological environment breeding method. That is, artificially creating a water area that meets the environmental conditions for the production of pollution-free aquatic products to carry out pollution-free culture, such as: farming of shrimp and crabs with grass. Now it has been developed into pollution-free shrimp and crab culture; grape or vine plants are planted on fish pond dumplings. The use of awnings to raise frogs has become a common type of frog ecological farming; livestock, poultry, aquaculture and forage grass are combined together, and livestock, poultry, fish and pond slopes are fed with pollution-free commercial feed. Feeding grasses to raise fish and livestock, livestock and manure fertilizers are fermented by biogas digesters to make forage grasses and cultivate water quality fertilizers; in winter, pond pond fertilizers can be used as base fertilizers for grass cultivation. This artificial ecosystem farming method , is a form of development potential of pollution-free aquaculture. Second, the use of microbial preparations culture method. In the past 10 years, microbial microbial preparations have been gradually applied in aquaculture, which has provided strong protection for pollution-free and healthy aquaculture production. At present, more products are used photosynthetic bacteria, Bacillus, Lactobacillus preparations, probiotics, Xifei Li, EM preparations. They can decompose the organic matter such as residual baits and fish dung in the water, reduce the ammonia nitrogen content in the water, make the aquaculture water body cleaner, and thus improve the environment; in addition, they can improve the gastrointestinal tract environment of the cultured subjects and increase appetite; Strengthen the immune function of the breeding object, improve immunity, and enhance disease resistance. Third, more varieties of three-dimensional breeding method. Aquatic animals live in different water layers under the control of the food chain, forming a relatively stable ecological balance and playing an important regulatory role in protecting and improving the ecological environment. Applying this principle to aquaculture production, a multi-species three-dimensional polyculture method has been formed. For example, grass carp (or grass carp) is the main fish culture. Mixing a certain amount of plutonium, alfalfa, cockroach, pupae, etc. in the same pool is a representative model. The combination of varieties of this model is very reasonable: using grass (or part of the commodity) to feed grass carp (or cockroach), the excrement they excrete can be fertilizer and water, which is conducive to the cultivation of plankton, and pupae, pupae and filter-feeding plankton reduce the water quality, The crickets and clams also feed on the leftover bait, detritus, and benthos, which play a role in cleaning the environment. Through the joint action of maggots, cockroaches, cockroaches, and cockroaches, it not only purifies the water environment, but also promotes the growth of grass carp (or grass carp), the main cultivar. If properly matched with a bit of fierce carnivorous fish (such as cockroaches, cockroaches, clams, oysters, etc.) in the system, use of them to eat wild fish in aquaculture waters and fish bodies with poor or ill health can not only prevent The incidence of major breeding species and the spread of diseases can also reduce costs and increase income. Fourth, closed-cycle water factory farming method. This is one of the most advanced production modes of aquatic products today. He is in a specific aquaculture facility, using modern high-tech means to conduct multiple sterilization and disinfection of aquaculture water, heating and oxygenation, feeding pollution-free feed, so that the breeding object is always in the best living and growing environment. Products are not only pollution-free, but also meet the requirements of green food. However, this breeding mode has the characteristics of high input, high output, and high risk. At present, it is only suitable for popularization and application in the surrounding areas of large and medium-sized cities and economically developed water-scarce regions. Fifth, open flow or micro-water aquaculture method. This method mainly uses the natural fall of rivers and lake reservoirs for flow culture. Due to good water quality and excellent environment, supporting the use of non-environmental pollution feeds, and raising famous fish, as long as the appropriate breeding density, it is rarely diseased. Therefore, it is not necessary to use drugs or very few drugs, and the product can usually meet the standards of pollution-free aquatic products. Six, aquatic product and crop reciprocity breeding method. This mainly refers to past methods such as paddy field cultivation, alfalfa field cultivation, mushroom field cultivation, and paddy field cultivation. Now it must be produced in accordance with the standards of pollution-free aquatic products, strictly control the use of pesticides, reduce drug residues, and ensure the greenness of aquatic products.
