Most of the shrimp shells are eaten by the shrimps again in the early stage of cultivation. In the later stage of cultivation, when the cultivation density is increased, the number of the shrimp shells or dead shrimps is increased, and a large amount of shrimp shells or dead shrimps can be accumulated at the water outlet. When the breeding pond discharges sewage, in order to avoid live shrimps from escaping from the water outlet, a layer of filter screen is generally required to cover the water outlet or the water outlet pipe of the breeding pond. The filter screen only allows small particle substances such as the excrement of the shrimps to pass through, but not allows the live shrimps to pass through. However, the shrimp shell and the dead shrimp are hard and the size of the shrimp shell and the dead shrimp is the same as that of the live shrimp, and the shrimp shell and the dead shrimp cannot pass through the filter screen. However, the accumulation of too much shrimp shells and dead shrimps can cause the blocking of organic matters such as shrimp feces at the water outlet. If the organic matters such as the shrimp feces and the like cannot be discharged out of the culture pond in time for separation treatment, the organic matters can be decomposed into soluble substances such as ammonia, nitrite and the like under the action of bacteria in water, and the substances have toxic action on the growth of prawns.
