Anfeng Town, Xinghua City, declared war on the tailwater of river crab farming

On November 13, Anfeng Town, Xinghua City, held a mobilization meeting for the treatment of tailwater from river crab farming, mobilizing the whole town to go all out to declare war on river crab farming tailwater. At the meeting, Anfeng Town issued an implementation plan on the implementation of the tailwater treatment of river crab farming, and signed a letter of responsibility for the tailwater treatment of river crab farming with each village.

Anfeng Town is the "hometown of China's river crabs", the town has a variety of aquaculture water area of 178,000 mu, of which 38,100 mu of ditch and pond aquaculture area, 139,900 mu of embankment aquaculture area, river crab annual output of 98,000 tons, output value of 1 billion yuan, driving 38,000 people to employment and entrepreneurship, to promote the high-quality development of the town's economy and society. With the rapid development of the river crab breeding industry, the ecological environment "old and difficult" problem caused by the discharge of aquaculture tailwater has become more prominent. Driven by economic interests, some farmers do not regulate the use of drugs, direct discharge of aquatic grasses into the river, and disorderly discharge of tailwater, which seriously affects the healthy and sustainable development of the river crab industry and brings greater pressure to the construction of the local ecological environment. From the perspective of protecting the sustainable development of fishery resources, Anfeng Town aims to create a leading benchmark in the ecological breeding industry, gathers the strength of decisive victory, implements a 14-month special action for the tailwater treatment of river crab farming, effectively solves the "old and difficult" problems of the ecological environment around the masses, and ensures that a river of clear water flows eastward.

Anfeng Town highlights source prevention and control, comprehensive policies, promotes the ecology of breeding methods and tailwater treatment facilities, and plans to use one year to implement the corresponding tailwater treatment area through "in situ restoration + ectopic restoration", establish aquaculture tailwater treatment facilities, apply new technologies and new processes such as physical and biological purification treatment, accelerate the construction of aquaculture water circulation treatment system, and achieve recycling water reuse and standard discharge.

In the tailwater treatment of river crab farming, Anfeng Town promotes ecological breeding, on the basis of reasonable layout, optimizes the breeding varieties, introduces the "Yangtze River No. 1" and "Yangtze River No. 2" river crabs, "Taihu No. 1" and "Taihu No. 2" green shrimp, trial breeds "Taihu Bream", "Youhu No. 1" and other excellent varieties with good benefits and less pollution, and at the same time vigorously promotes the ecological three-dimensional breeding mode such as multi-species polyculture, rice fishing, and comprehensive breeding of rice frogs, and integrates the application of environment-friendly breeding technologies such as energy conservation and emission reduction, land and water saving, etc. Promote the quality of aquatic products and the improvement of the water environment. In 2022, the town will promote multi-variety polyculture area of 60,000 mu and "rice + N" mode planting area of 20,000 mu.

Anfeng Town revised and improved the operating procedures for the tailwater treatment technology of river crab farming, and popularized the knowledge of pollution-free river crab breeding water quality specifications, crab medicine use guidelines, and key points for the use of crab compound feed to crab farmers; Establish a river crab inspection and testing center to strengthen the sampling of river crab production and circulation links. Anfeng Town adheres to the annual inspection system of crab seedling breeding farms, accelerates the pace of improvement of river crab seedlings, builds 5 standardized crab seedling breeding bases, and strives to achieve a production capacity of 1 billion crab seedlings in the town. At the same time, we should do a good job in the supervision of inputs, run the supervision of inputs through all aspects of production, sales and use, and achieve the "five unifications" of unified seedlings, unified disinfection and disease prevention, unified feed, unified medication, and unified sales, and gradually establish and improve the traceability system for the quality of river crabs.
