[0002] Fish farming is an important way to obtain aquatic products. Generally, farming needs to be carried out in ponds, cages or fences. Excavating ponds not only needs to occupy land, but also use machinery to excavate and organize the land, which is labor-intensive, time-consuming and expensive. Although the cost of setting net cages and net enclosures on large water surfaces is low, they are restricted due to their great impact on water quality and failure to meet environmental requirements. Gradually decreasing, under the condition of not polluting the water environment, it is necessary to explore new fishery production methods to obtain more aquatic products and meet people's requirements

Embodiment Construction
[0008] The present invention is illustrated in conjunction with the accompanying drawings, a semi-enclosed floating multi-layer ecological breeding water tank, characterized in that the water tank is composed of a water tank floating ring 1, an upper filter water-permeable ring 2, a water tank upper edge water-proof ring 3, and an upper grille plate 14. The vertical wall of the closed water tank 8, the middle grille plate 15, the bottom grille plate 17, the conical water tank bottom 9, the sewage filter cover 11, the sewage storage tank 22, the inflation system, the sewage system, and the bait delivery system; The main body is a cylindrical shape with a closed periphery made of a closed water tank vertical wall 8. The closed water tank vertical wall 8 is made of transparent polyethylene material. The water tank body has a diameter of 5-10 meters and a height of 1.5-2.2 meters. Made of transparent polyethylene material, the upper mouth of the conical water tank bottom 9 is consi...

Abstract
The invention designs a semi-closed floating type multi-layer ecological culture water tank. The water tank comprises a water tank floating ring, an upper-layer filtering water permeable ring, a watertank upper-edge water partition ring, an upper-layer grating plate, a sealed water tank vertical wall, a middle-layer grating plate, a bottom-layer grating plate, a conical water tank bottom, a sewage discharge filtering cover, a sewage storage tank, an inflation system, a sewage discharge system and a bait feeding system. By using the water tank, planktonic feeding fishes are stocked in an upper-layer culture area, feed eating fishes are stocked in a middle-layer culture area, and bottom fishes are stocked in a bottom-layer culture area. An inflation system is used for conducting inflation and oxygen enrichment on a water area of the water tank, a bait feeding system is used for feeding bait, residual bait enters the bottom-layer culture area to be eaten by the bottom fishes, fish manureand other pollutants are accumulated in the sewage storage tank, and the accumulated pollutants are discharged out through a sewage discharge pump. At the same time, the upper-layer filtering water permeable ring on the upper portion of the water tank body filters surrounding water when the pollutants are discharged, the water then enters the water tank body, only a small amount of water needs tobe supplemented, the culture waste pollutants are extracted from the water area for discharging, the surrounding environment of the culture areas is not influenced, and the requirements for ecological and environmental protection are met.
