Background technique

Aquaculture is the productive activity of multiplying, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture has extensive culture, intensive culture and high-density intensive culture. Extensive farming is to put seedlings in small and medium-sized natural waters, and develop aquatic products entirely by natural bait, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive culture is the cultivation of aquatic products by feeding and fertilizing methods in small water bodies, such as pond fish culture, cage fish culture and pen culture.

At present, most of the water in aquaculture ponds is static and has poor fluidity. Self-contamination sources such as bait and fecal excrement of farmed animals accumulate at the bottom of the pond. If they are soaked in water for a long time, they will rot and deteriorate under the action of microorganisms, and dissolve N, P, etc. It can cause the accumulation of harmful substances such as ammonia nitrogen and COD in the water body, and it is also easy to cause diseases to be rampant and seriously affect the water quality. Therefore, it is often necessary to change the water in the whole pond on a regular basis. Conducive to the normal growth of farmed animals.
