Moving "fish's home" into the "giant bucket", "zero emissions" environmental protection fish output increased by 15 times

The Yangtze River Daily Da Wuhan Client August 31st News Moving the "Fish's Home" into a "giant bucket" from the pond, this fish farming method of Wuhan Huafengju Ecological Agricultural Development Company, not only the annual fish producing fish production It is about 15 times higher than the traditional water surface farming, and zero emissions can be achieved.

On the 31st, at this aquatic base in Wangjiahe Street, Huangpi District, a reporter from the Yangtze River Daily saw a row of "giant buckets".

On the escalator and standing next to the "bucket" more than 2 meters high, you can see the full picture of "bucket" about 8 meters in diameter. The water flow in the "giant bucket" is constantly no fish. Once they are eaten, it will lead to countless fish floating.

Zou Shenghua, general manager of the company, introduced that this "giant bucket" is called the land -based circle. It is a kind of aquaculture equipment based on mature products in combination with market mature products.

The capacity of each land -based ring nourishing pool is about 125 cubic meters, which can breed special aquatic products such as sea bass and mushrooms. The annual output of a single pool is 8,000 to 10,000 kg, which is much higher than that of traditional ponds. He introduced interestingly that because the water in the pond is constantly circulating, the fish in the pond has been exercised more than the fish pond breeding.

The true characteristics of the land -based circle nourishing ponds are that the facility has the dual characteristics of saving the area of ​​the aquaculture water and environmental protection and energy saving. Zou Shenghua introduced that the circular pool is connected to the ecological pool built by the external network through the pipe network. The fish is in the circle of nursing ponds and grows through artificially. Microfiller and ecological pool physical filtration and ecological purification, re -inject the ring nursing pool to form a closed -loop recycling system.

Liu Zidong, a senior engineer of Wuhan Aquatic Products Technology Promotion and Guidance Center, introduced that in the traditional aquaculture, after several years of pond breeding, the water and dredging of water and such as residual bait, excrement, etc. will consume water. The natural purification of ecological pool water plants and pupae can be used for recycling, which can improve the utilization rate of water body and reduce environmental pollution at a high degree. "The filtering organic matter is used as the fertilizer of plants in the park, and the aquatic circulation breeding basically achieves 'zero emissions'."

The water body used by cleaning cycles also allows high -density breeding in the breeding circle.

At present, there are more than 60 circular land -based ring nourishing ponds and similar container farming waters in the aquatic base, and cultivate special aquatic products such as bass, mushrooms, cod, and round kisses. The fish can reach about 2 million kg. Next month, a group of sea bass at the base will be listed on sale.

It is reported that the breeding model of the circle of centered ponds is around 2018. It is a new type of aquaculture facility breeding model. It has the characteristics of ecological environmental protection and green emission reduction. It is the current green, healthy and high -quality breeding model that the city has developed vigorously.
