“Fish and vegetable symbiosis” zero emission ecological and economic benefits double harvest

In modern facilities greenhouses, fish ponds are arranged in a row, and various freshwater fish swim freely in the water; On the three-layer three-dimensional vegetable planting rack, various vegetables are thriving… In the “Fish and Vegetable Symbiosis” ecological farm of Deqing Baiyuankang Ecological Agriculture Co., Ltd. (hereinafter referred to as “Baiyuankang”) located in Deqing County, Zhejiang Province, the scene of fish and vegetables “harmonious coexistence” and common growth has become a daily phenomenon.

In recent years, the People’s Government of Luoshe Town, Deqing County has continuously strengthened the integration of the three industries, combined with market supervision, health and other departments to strengthen guidance for food production enterprises, and gradually opened a new chapter of sustainable circular zero emission low-carbon production. One typical case is Baiyuankang’s “fish vegetable symbiosis”.

Baiyuankang is located in the National Rural Industry Integration Demonstration Park in Dongheng Village, Luoshe Town, covering an area of 120 acres. Adopting a modern and high-tech hybrid production method that combines planting and breeding, Baiyuankang combines four technologies: “industrialized circulating water aquaculture”, “soilless cultivation”, “fish vegetable symbiosis”, and “efficient active peptide concentration and separation”. Through the complete construction of animal, plant, and microbial ecological chains, it achieves a sustainable, recyclable, efficient, pollution-free, full biological cycle, and fully controllable biological agricultural production model.

Water flows out of the fish pond and undergoes complex treatment processes. The fecal residues are converted into nutrients required by the planting system through the microbial system. After being absorbed and filtered by the vegetable roots, the circulating water returns to the aquaculture pond. At Baiyuankang’s “fish vegetable symbiosis” ecological farm, we have achieved the goal of “raising fish without changing water, and planting vegetables without fertilizing”. At present, Baiyuankang has constructed more than 10 “fish vegetable symbiosis” projects, continuously replicating and expanding the ecological agriculture industry.

The relevant person in charge of Baiyuankang stated that the “fish vegetable symbiosis” model deviates from soil cultivation and avoids the use of pesticides. The vegetable yield is more than 5 times higher than traditional cultivation, and the fish yield is 10 times higher than pond aquaculture. While the production method is more environmentally friendly, the economic benefits are also significantly improved. In addition, there is also guidance from government departments in terms of production standards, fundamentally ensuring the quality and safety of fish and vegetables.

Fishing nets, fish barrels, and other fishing gear cannot be used interchangeably. It is strictly prohibited to touch water bodies with hands, and timely disinfection and sterilization are clearly stipulated, “said the relevant person in charge of the Luoshe Office of the Deqing County Market Supervision Bureau. It is understood that the People’s Government of Luoshe Town, in conjunction with the market supervision department, has seized the key point of food safety and ensured that employees produce qualified products according to requirements by urging Baiyuankang to strengthen employee training and standardize production operations.

Moreover, on the basis of fish and vegetable cultivation, Baiyuankang has broken through the conventional production and preparation process of active peptides, that is, by stimulating fish to synthesize small molecule peptides with unique biological functions, secrete them into aquaculture water bodies and extract them, and then carry out deep processing of peptide series products, further extending the “zero emission” ecological agriculture industry chain. At present, Baiyuankang has launched and sold three peptide products.

In addition, the People’s Government of Luoshe Town has collaborated with Baiyuankang to build a health research and learning camp, exploring the establishment of a new pattern of diversified ecological agricultural industry development through the production and research of a zero emission base that combines ecological and environmental protection with planting and breeding. At the same time, Baiyuankang actively helps other peers to jointly develop the health industry by sharing experiences.

The zero emission production model of ‘fish and vegetable symbiosis’ can bring higher output, lower costs, better environmental protection, and more employment opportunities to the agricultural industry in Deqing area, while promoting agricultural modernization and sustainable development. In the future, we will continue to explore the way in which one production of biological farms drives the integration of two and three industries, and promote this ecological and economic benefits dual harvest planting model to a greater extent The relevant person in charge of the People’s Government of Luoshe Town said.
