Like fish farming in rice fields, fish vegetable symbiosis is also a technology that has moved from ancient times to modern times, from tradition to innovation. In the past decade, fish and vegetable symbiosis and aquatic pastoral technology have been promoted and applied nationwide as one of the eight main models of modern aquaculture technology promoted by the Ministry of Agriculture and Rural Affairs. Chongqing Tongnan, Bishan, Dianjiang, Sichuan Chongzhou, Jianyang and other places have actively demonstrated and achieved good results. In today’s global emphasis on ecological and biodiversity conservation, bioremediation technology is widely recognized as the most economical and effective remediation technology for water environment. And this technology conforms to the trend, not only doing a good job in ecological protection and building beautiful homes, but also increasing the economic income of farmers and promoting rural revitalization.
By planting various plants on the surface of the pond, utilizing plant roots to absorb nitrogen, phosphorus and other plant nutrients formed by the decomposition of fish excrement in the water, and through the symbiotic and mutually beneficial relationship between fish and plants, fish farming is achieved without pollution or less pollution, wastewater is not discharged, vegetable planting is not fertilized, and fish and vegetable dual harvest are achieved. The pond water environment is effectively repaired, which is a comprehensive planting and breeding model that can recycle resources.
A large amount of organic matter stored at the bottom of the pool can be gradually elevated to the surface for oxidation and decomposition through technical measures, for plant species to absorb and utilize. Through long-term consumption, the pond sludge gradually decreases, and the entire pond water environment is effectively restored.
Through water pastoral technology, the pond water environment has been restored, resulting in a thinner water body that is not conducive to the growth of parasites and pathogens. This objectively reduces the density of parasites and pathogens and reduces the risk of fish disease.
When the water is good, the number of fish getting sick will be reduced, and the dosage will inevitably be reduced. This will not only save the cost of medicine, but also help to ensure the quality and safety of aquatic products. The quality of fish that implement fish vegetable symbiosis technology is better than that of fish that do not implement fish vegetable symbiosis technology, which is also the principle of good water culture and good fish.
Which fish are mainly farmed in aquatic fields? Different breeding varieties have different technical models, one of which is the symbiotic technology of non herbivorous fish and fish in ponds. In ponds where non herbivorous fish such as catfish, catfish, and catfish are mainly raised, shading nets are used as floating beds and water spinach is planted to purify water quality.
