Abstract：Changli Reservoir is located in the northwest of Donghai County, Jiangsu Province, in Shuangdian Town. It is situated in a warm-temperate humid monsoon climate zone with distinct four seasons. The average annual temperature is around 15°C, with abundant precipitation, an average annual rainfall of about 913 mm, and a frost-free period of 225 days throughout the year. The average annual sunshine duration is about 2,300 hours, with ample sunlight. The reservoir has a catchment area of 52,500 mu, with an average surface area of about 3,000 mu, an average water depth of 3 meters, and a storage capacity of 21.11 million cubic meters during the flood season. The water quality of the reservoir is clear, the water area is vast, and there are rich aquatic plants and animals, with sufficient natural feed, making it a natural aquaculture site. This water surface was contracted by Li Qianfang from Shili Street, Donghai County, in 2015 for aquaculture, and has had 10 years of experience in large water surface aquaculture. He has his own unique insights into aquaculture technology and disease prevention in large water surfaces. The following is a summary of related aquaculture technologies and disease prevention techniques and experiences, for reference by the broader fish farming community.
