The Bureau of Agriculture and Rural Affairs of the Chinese city of Qinzhou recently organized a meeting for the promotion of the fishery and aquaculture wastewater treatment facility. The meeting was attended by more than 60 people interested in further developing aquaculture with modern facilities while protecting the environment.
Other priority objectives of the meeting were to promote the transformation and improvement of the fish farming industry, to build a modern and high-performance working system, without losing sight of product safety, resource conservation and respect for the environment.
Among those attending the meeting were leaders of the fishing and aquaculture sector, as well as representatives of the Qinzhou Municipal Bureau of Agriculture and Rural Affairs, members of the same department in Qinnan District, the Social Affairs Bureau of the Qinzhou Port Area Free Trade Zone and representatives of aquaculture companies.
“During the meeting, they visited the facilities of three fishery and aquaculture wastewater treatment demonstration facilities, called ‘Three Ponds and Two Dams’ and located in Hengfeng Village in Qinnan District itself.“
There, Qin Bozhong, deputy director of the Municipal Aquatic Technology Promotion Station, explained in detail the operation of the ‘three ponds, two dams’ system and a wetland treatment mode, which unifies the farms.
The company’s scientific design has improved traditional drainage channels into ecological ditches. In addition, it has adopted the ‘three ponds, two dams and one wetland’ system to treat aquaculture farm wastewater, greatly reducing nitrogen and phosphorus content, and effectively improving the rearing and breeding environment.
360 shrimp breeding greenhouses
Meanwhile, in Qinnan District, technician Liu Darong from Jianshan Agricultural and Rural Service Center introduced the base construction plan in detail. Darong, one of those responsible for setting up the greenhouse shrimp breeding base of the local professional aquaculture cooperative, explained that by the end of March 2021, 360 shrimp breeding greenhouses were installed and the ‘three ponds and two dams’ for treatment were built.
Also visited were Kenong Planting Professional Cooperative’s shrimp breeding base with ecological circulating water in a land-based circular pond and Qinzhou Shengnong Aquaculture’s greenhouse breeding base, both in Qinnan District. In the latter, the technician in charge explained the breeding mode, single pond production, market price, economic benefits and gave data on product marketing and promotion.
After the tours, the event ended with a symposium, during which the researcher of the Qinzhou Agriculture and Rural Affairs Bureau, Fu Lanfang, gave an overview of the landscape of modern fishing and aquatic product facilities.
“In his lecture, Lanfang talked about the requirements for developing modern fish farms with strength, improving traditional aquaculture, while promoting the development of high-quality farming in Qinzhou.“
At the same time, the researcher from the Bureau of Agriculture and Rural Affairs stressed the importance of installing wastewater treatment technology when developing farming facilities. Finally, he reminded that the direct discharge of such water is strictly prohibited, always to ensure the environmentally friendly development of aquaculture, as well as its high yield and efficiency.
Recall that, at present, aquaculture in facilities is developed in the city through multiple modalities. The main ones are the hanging culture of large-sized oysters; the one carried out in deep waters in storm-resistant cages; the culture in shrimp factories; the culture in shrimp greenhouses; the culture in circular ponds on land; and the culture in circulating waters.
50% of Qinzhou’s fish production
Fish farming production from the facilities located in the city reached 281,000 tons in the last period, accounting for more than 50% of the city’s fish production.
According to the Qinzhou Municipal Bureau of Agriculture and Rural Affairs, the city will continue to promote fish production in modern facilities, form a reverse force mechanism, guide major aquaculture entities to develop their production in environmentally friendly facilities in an orderly and scientific manner, and accelerate industrial transformation and upgrading.
At the same time, the bureau members highlighted the importance of attracting investment in fish farms, attracting social capital to develop facilities, assisting the development of fisheries in the city, and contributing to the social and economic development of Qinzhou.
