A layer of conical shaped wells 100 and corresponding first drain valves 310 may be provided in the fish pond 5 and aquaculture may take place in the body of aquaculture water 7 above the layer of conical shaped wells 100.

Two layers of conical holes 100 and corresponding first drain pipe valves 310 can be arranged in the fish pond 5 at intervals up and down, and aquaculture is carried out in the aquaculture water body 7 above the two layers of conical holes 100 respectively. The tapered cavity 100 may be made of a transparent material so that light is obtained from the aquaculture water 7 arranged above the lower tapered cavity 100. A light emitting device can be arranged at the lower side of the conical hole 100 structure arranged at the upper layer to supplement illumination for the culture water body 7 above the conical hole 100 arranged at the lower layer. Two layers of conical holes 100 are arranged in the culture water body 7, so that two aquatic animals can be respectively cultured, and a string prevention structure is arranged between the two layers, so that the two aquatic animals are prevented from being mixed.

In specific use, the structure of the conical cave 100 is immersed in the aquaculture water 7 in the fish pond 5, that is, each part of the structure of the conical cave 100 can be balanced by the pressure of the aquaculture water 7, and the advantages of the structure of the conical cave 100 are that the requirement on the water pressure resistance is low, the manufacturing cost of the structure of the conical cave 100 is low, and the connection process of the conical cave 100 and the sewage pipes is simple, easy to maintain and low in use cost. The function of the conical well 100 is to intercept the free-settling aquaculture manure and to organize it to collect at the bottom of the conical well 100. If the fish pond 5 is arranged above the land surface, the water surface of the culture water body 7 is obviously higher than the land surface, and the bottom 6 of the fish pond is close to the land surface, the culture feces can be timely removed under the condition of not consuming energy only by the pressure of the culture water body 7. If the fish pond is located in a pit significantly below the ground or in the natural body of water 11, these farmed manure will need to be pumped out of the conical pit 100 by a drain pump provided on a drain valve. The conical hole 100 is arranged in the fish pond so as to prevent the culture manure from settling at the bottom 6 of the fish pond and being difficult to remove in time so as to influence the quality of the culture water body 7.

The fish pond 5 of the present invention may also be disposed in a natural body of water 11, including rivers, lakes, and reservoirs.
