Fish and vegetable coexisting in one water “double harvest”

Located in the depths of the Taihang Mountains, Ganquan Jing Village used to have no Ganquan, let alone wells. For generations, it relied on dry wells to collect rainwater or fetch water from neighboring villages a few miles away. A few years ago, deep wells were drilled and reservoirs were built in the village, completely bidding farewell to the bitter days of difficult drinking and water use.

What is fish vegetable symbiosis? Zhao Xiaobo, the head of Xingsheng Vegetable Planting Professional Cooperative in Pingding County, Yangquan City, explained that fish vegetable symbiosis is a new type of composite farming system. It combines aquaculture and hydroponic cultivation, two completely different technologies, through clever ecological design, allowing fish and vegetables to coexist in synergy. Everything that happens in the fish vegetable symbiotic greenhouse is like a natural ecological chain – fish grow in fish ponds, and the aquaculture tail water is filtered to remove nutrients left by fish manure, making it suitable for vegetable cultivation; The tail water from vegetable planting flows back to the fish pond after disinfection and sterilization, which is not wasteful for fish farming.

The fish and vegetable symbiosis project of Xingsheng Vegetable Planting Professional Cooperative in Pingding County, Yangquan City covers an area of nearly 10 acres and has three fish and vegetable symbiosis greenhouses. In the vegetable planting area, water lilies float on the water like sleeping beauties. The water in the pool is flowing and clear to the bottom. In the fish farming area, bass, tilapia, koi, and other fish are swimming freely in the water and are expected to be available for sale in a while.

The fish and vegetable symbiosis project was only recently completed and is currently in the exploratory The fish and vegetable symbiosis project was only recently completed and is currently in the exploratory stage, “said Zhao Xiaobo, In terms of vegetable cultivation, the first batch of water lilies were tested. If the water lilies are growing well, the next step is to ‘move’ lettuce, sea cabbage, celery, and other vegetables to hydroponic ponds. In terms of fish farming, there are currently 13 fish ponds in the greenhouse, raising more than 30000 fish of different types and high economic value. If the farming is successful, we plan to increase the variety of fish breeding based on market demand.

Although the project covers a large area and earns a lot of income, there are not many workers working in the fish and vegetable symbiotic greenhouse. Originally, the entire cycle of the project was automatically completed by an intelligent system, and workers only needed to manage fish and vegetables. Impurity filters, water circulation systems, dissolved oxygen controllers… In order to build a good fish and vegetable symbiosis project, the Xingsheng Vegetable Planting Professional Cooperative in Pingding County, Yangquan City has added many intelligent equipment, reducing labor intensity for workers and improving work efficiency.
