Abstract：Crab management measures. 'Scientific Fish Farming': What are the main impacts of the plum rain season on crab farming? How to reduce the impact? Cheng Yongxu: The plum rain season in the middle and lower reaches of the Yangtze River has a multifaceted impact on crab farming, including the crabs themselves, aquatic plants, and environmental factors, which are interrelated and influence each other. Every 5-7 days, use potassium peroxysulfate compound salt (200 grams/acre) to improve the bottom. After the rain, spray slaked lime (5-10 kilograms/acre) to stabilize pH, and promptly turn on the aerator to increase the dissolved oxygen content in the water.
