Industrial aquaculture system and method for prawns

The industrial aquaculture system comprises an aquaculture pond, an upper cover is fixed to the top of the aquaculture pond in an inserted connection mode, a limiting block is fixed to the inner wall of the aquaculture pond in a welded mode, and a stainless steel net plate is placed on the limiting block; a water body purification structure is arranged on the lower side in the culture pond and comprises a supporting net frame, bolting-silk net cloth and a sand bed; a mounting groove is formed in the bottom of the culture pond, and an air inlet branch pipe is mounted in the mounting groove through a support. The invention further discloses a corresponding breeding method, water flow is driven by air flow to form a circulation system, the sand bed not only plays a role in filtering, but also can become an effective carrier of a micro-ecological system to keep the stability of the micro-ecological system, and therefore it can be guaranteed that water is not changed or a small amount of water is added within thre
