Scientific stocking of fish stocking is the key link of aquaculture, we should grasp the principle of “five can not be ignored”. First, you can not ignore the Qing Tong disinfection. Fish species must be drained before drying ponds, remove silt, tamp pool, repair the sluice, to create a good environment for fish growth. At the same time Qing Tong disinfection. Dry pond, per acre (1 mu = 667 square meters, the same below) with lime 70 to 80 kg of water Quanchiposa. With clear ponds, available lime per acre 125 to 150 kg of splashed water. Second, we can not ignore the quality of fish species. Fish species quality requirements complete scale, neat specifications, bright color, strong physique, swimming lively, anti-water strong. Stocking varieties and quantity should be based on food, water quality and other conditions identified, grassland is rich
