As the saying goes, fish can not do without water. Water is the place of fish’s life activities, and its relationship can be understood from what people often refer to as “fish and water”. To fish high yield, we must first have a more suitable water environment, that is, fresh water, adequate oxygen, no poison. The water quality is closely related to the environmental conditions of the pond. The environmental conditions of the high-yielding fish ponds are as follows: ① area of 4-10 mu and water depth of 2-3 m; ② rectangle with east-west orientation with aspect ratio of 2: 1; Medium viscosity of loam, sediment thickness of about 20 cm of sludge, in order to facilitate water and fertilizer, fertile water; ④ water
