The”Jianghan Lakes Clean Aquatic Water Purification Biology-Ecological Basis and Guarantee Strategy” jointly declared by the Yangtze River Fisheries Research Institute of the Chinese Academy of Fishery Sciences and the Institute of Hydrobiology of the Chinese Academy of Sciences won the 2020 National Natural Science Foundation of China Regional Innovation Development The joint fund focuses on funding. The project strives to study the water ecological effects of pond farming and rice-fishing integrated farming models by analyzing the sources, transformations and causes of nitrogen and phosphorus in typical aquaculture models of Jianghan Lakes within 4 years; research on enhanced cleanliness from the perspective of biology and ecology Aquatic water purification mechanism, clarify the nitrogen and phosphorus cycle mechanism in the pond-purified wetland clean aquatic system and the biological-ecological synergy mechanism of net zero discharge of the system tail water; reveal the nitrogen and phosphorus recycling and energy efficiency of the rice-fishing integrated planting and breeding system The mechanism of flow; finally determine the tail water discharge threshold based on the cultivation capacity and the functional zoning of the receiving water body.
In order to successfully complete this goal and task, from April 1 to 2, 2021, the Institute of Hydrology and the Yangtze River Institute jointly visited Jingzhou, located in the core area of the Jianghan Plain, to investigate the basic situation of the project implementation area in order to formulate feasible Experimental research program. The investigation was led by researcher He Feng, director of the Institute of Hydrobiology, researcher Li Chuangju, deputy director of the Yangtze River Research Institute, researcher Zhang Hui, director of the research office, and core members of the project, including researcher Li Zhongjie, researcher Li Gu, researcher Qiu Dongru, researcher Zhou Qiaohong, and researcher Xu More than 20 experts including researcher Dong participated.
At the Pond Ecological Engineering Technology Research Center of the Chinese Academy of Fishery Sciences, which is based on the Yangtze River Research Institute, everyone visited the center’s current operations including ditch wetland-pond compound circulating aquaculture, rice field-pond compound planting and indoor integrated circulation The clean aquaculture model of aquaculture and other systems, and highly praised the compound pond culture concept, ecological filter construction technology, immobilized ecological floating bed technology and rice field ex-situ restoration technology. In the Agricultural Science and Technology Park of Yangtze University in Jingzhou Agricultural High-tech Zone, everyone visited different types of ecological planting and breeding models, and listened to Professor Zhu Jianqiang from Yangtze University on the field engineering transformation, water quality control, breeding separation, and non-point source of rice and shrimp model research and development. Introduction to systematic work such as pollution control. Through on-site visits, everyone said that the bases for this investigation all have complete infrastructure and scientific research conditions, which provide a basic guarantee for the smooth implementation of joint fund projects.
Director He Feng said that the joint fund provides conditions for the close cooperation between the Yangtze River Institute and the Institute of Hydrobiology, and this survey marked the official launch of the project. Deputy Director Li Chuangju hopes that the team members will unite and cooperate, seek truth and be pragmatic, and work out research and technical routes around the project goals, and finally form a comprehensive decision-making system for clean aquaculture that takes into account the ecological and environmental requirements of the Jianghan Lakes. It is a good choice for the Jianghan Lakes and even Hubei aquatic products. The green development of aquaculture provides scientific and technical support.
