PROBLEM TO BE SOLVED: To provide a pond structure for land-based aquaculture, the structure being extremely simple and inexpensive in a mechanism for forming a circular flow, being also mild in a water flow speed, and being suitable for aquaculture of fry and young shrimp, and provide a land-based aquaculture method using the same.;SOLUTION: A pond structure is provided in which the water entering from an inflow port 5 flows to an outflow port 4 by an air flow AF from a main air diffusion unit 3 while bypassing along a sidewall of a pond body 2, and thereby a slow circular flow along a sidewall inner circumference of the pond body 2 can be formed constantly. While depending on an extremely simple mechanism, water flow blind spots such as the lack of oxygen becomes hard to be formed in the pond body 2, the land-based aquaculture having more higher population density is made possible. Also, the formed current is gentle, the swimming against the water flow becomes easy even if aquaculture target species such as the young shrimp and fry are small, and thereby healthy aquaculture conditions where stress is hard to be accumulated and an extinction rate is low can be maintained.;SELECTED DRAWING: Figure 11;COPYRIGHT: (C)2019,JPO&INPIT
