Recently, researcher Xie Jun, associate researcher Gong Wangbao, and associate researcher Li Zhifei from the Pearl River Fisheries Research Institute visited Qingyuan City, Guangdong Province to carry out aquaculture green tail water emission reduction survey. Liu Zhihong, deputy director of the District Agriculture and Rural Bureau, received researcher Xie Jun and his party and introduced Qingxin’s main achievements in the adjustment of industrial structure.
Fresh freshwater aquaculture maintains the traditional scale breeding of large freshwater species such as bighead carp, silver carp, carp, carp, carp, etc. On the one hand, it develops and improves the quality of hanging water fish. On the one hand, it has successively introduced and promoted Feng carp, white pomfret, sturgeon, osmanthus, soft-shelled turtle, ornamental fish, Roche prawn, Australian freshwater crayfish, California perch, northern river bream, scallop, northeastern crucian carp, catfish, Yangtze river catfish, tilapia More than ten species such as fish. With the implementation of scientific cultivation, management, ecological breeding and other technologies, the average output value of ponds per mu has been increased from 800 to 900 yuan to 10,000 yuan, and the benefits have been greatly improved. A fresh and emerging aquatic industry represented by osmanthus fish farming has been formed, and has now become a pillar industry of the district’s rural economy. The osmanthus fish farming area in Qingxin District exceeds 30,000 mu, with an output of nearly 10,000 tons, and an annual output value of about 500 million yuan, accounting for nearly 70%of the fishery output value of the entire district. It has become a provincial industrial park and has obtained geographical indication product certification. Under the situation of rapid industrial development, Qingxin is currently encountering environmental protection pressure and technical bottlenecks of green transition tailwater emission reduction, and hopes the Pearl River will provide technical support.
Xie Jun, a researcher, said that Qingyuan and the Pearl River have a long-term cooperation basis. The next step will be the water area aquaculture capacity planning, green aquaculture model and tail water ecological treatment. Cooperation. After the meeting, experts from Pearl River Research Institute investigated the status of tail water treatment in Osmanthus Flower Industrial Park, Qingyuan, Foshan Junction Waters, and Hongye Aquaculture Professional Cooperative, and provided suggestions for the transformation and upgrading of aquatic products in the area.
