First, the artificial ecological environment breeding method The artificial eco-environmental culture method artificially creates a water area that meets the environmental conditions for the production of non-pollution aquatic products, and selects the appropriate cultured species for pollution-free culture based on the principles of aquatic ecology. For example, the cultivation of shrimps and crabs with grasses has become one of the main modes for the development of pollution-free shrimp and crab cultivation and the construction of large-scale ecological breeding bases; the planting of grape or vine plants on the pond of fish ponds is used to build shade sheds. , has become a common type of frog ecological farming; fish, livestock, poultry, grass (vegetable) organic combined breeding method, that is, livestock, poultry, aquaculture and forage grass planting together, using non-environmental pollution feed animal husbandry , Poultry, fish, ponds and slopes are reared on grasses to feed fish and livestock, and livestock and poultry manure are fermented and used as feed for fertilization and water quality cultivation. In winter, the fish pond fertilizer in Qingtang can be used as a base fertilizer for grass, thus forming a virtuous cycle of material flow. This artificial ecosystem breeding method is a form of development potential of pollution-free aquaculture. Second, microbial preparation culture method In recent years, microbiological live bacterial preparations have gradually been applied and promoted in aquaculture, which has provided strong protection for pollution-free and healthy aquaculture production. At present, more products are used in light Taiwan bacterial preparations, Bacillus, Lactobacillus preparations, probiotics, Xifei Li, EM preparations. They can decompose the organic matter such as residual baits and fish manure in the water body, 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 objects, increase appetite, promote growth, and improve Feed rewards; at the same time, they can also strengthen the immune function of the breeding object, improve immunity, and enhance disease resistance; it can also strengthen beneficial groups to prevent and reduce the occurrence and spread of bacterial diseases. Third, multi-variety three-dimensional breeding method Under the regulation of the food chain, aquatic animals live in different water layers, forming a relatively stable ecological balance, which constitutes the diversity of organisms and plays an important regulatory role in the protection and improvement of the ecological environment. Therefore, applying this principle to aquaculture production has resulted in the formation of a multi-species three-dimensional polyculture. For example, grass carp (or grass carp) is the main fish and a certain amount of plutonium, plutonium, alfalfa, alfalfa, etc. is mixed with the pond. The combination of varieties of this model is very reasonable; with grass (or some commercial materials) do not feed grass carp (or pupae), their excrement can be fertilizer, is conducive to the cultivation of plankton, plutonium, earthworms filter food plankton reduces the water quality鲤, while 鲤, 鲫 鲫 以 以 with grass carp leftover bait, debris and benthic organisms to eat, play a role in cleaning the environment. Fourth, aquatic product and crop symbiosis breeding method This mainly refers to the past "rice field cultivation", "Population of Pak Pak Tin," "Zi mushroom field farming," "Pud Tian breeding" and other methods, and now must be produced in accordance with the standards of pollution-free aquatic products Strictly control the use of pesticides, reduce drug residues, and ensure that the aquatic products are green and pollution-free. V. Open flow or microfluidic aquaculture The open flow or microfluidic aquaculture method mainly utilizes the natural fall of the water bodies of rivers and lakes to carry out aquaculture. 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.
