Report title: Basic situation of aquaculture water environment and wastewater treatment investigation in Guangdong Province

Dr. Wang Yaohua, R&D Director of Nutriera Group, shared the concept of comprehensive tailwater control from the source. He mentioned that manure is the root cause of water quality deterioration and pond wastewater discharge pressure. It is usually regarded as waste and becomes a burden on the water environment. However, under the concept of "Nutrition-Animal Health", fish and shrimp manure are regarded as a nutrient that can be recycled and reused. It is an effective technical solution to slow down water pollution and discharge in ponds: the front end uses innovative feed comprehensive technology to improve the efficiency of feed utilization and conversion and reduce fecal discharge, the back end uses the water body animal protection combination scheme to continue to decompose and transform water feces into small particles of nutrients or floc nutrients that can be utilized by zooplankton and phytoplankton, and fish & shrimp can further feed on zooplankton and phytoplankton, thereby greatly improving the recycling efficiency of nutrients, and starting from the source, greatly reducing the burden of wastewater emissions.

Dr. Wang Yaohua, R&D Director of Nutriera Group, made a report on "Application Strategy of Nutrition-Animal Health Technology in Comprehensive Treatment of wastewater"

Since Nutriera Group firstly proposed the technical concept of "Nutrition-Animal Health" in the industry in 2019, it has carried out in-depth theoretical research and practical innovation in response to this concept. The concept of "Nutrition-Animal Health" pioneered by Nutriera Group has been registered for copyright, and gratifying results have been achieved in many species such as largemouth bass, yellow catfish, grass carp, and white leg shrimp. In order to share the latest progress in animal nutrition and animal health with the industry, Nutriera Group launched a series of activities of "Nutrition-Animal Health Expert Lecture Hall", which has received high attention and recognition from the industry. In the future, Nutriera Group will further give full play to its advantages in technological research and development, and cooperate with scientific research institutions and related units to explore and optimize wastewater comprehensive treatment technologies and schemes, and make unremitting efforts to promote the transformation of aquaculture fishery industry and the green and healthy development.
