Circulating water symbiotic aquaculture device for aquatic animals and plants

The utility model belongs to the field of symbiotic aquaculture devices for aquatic animals and plants and discloses a circulating water symbiotic aquaculture device for the aquatic animals and plants. The technical problems that according to an existing circulating water fish culture device, cost is high and cultivated objects face survival risks are solved. A carrier pipe extends into an aquaculture box from the bottom of the aquaculture box and reaches to the upper portion of the aquaculture box, a water outlet of the carrier pipe is located above an aquaculture groove, a water pump is installed on the carrier pipe, an inclined plate is installed on the lower portion inside the aquaculture box, and a return pipe is installed at the bottom of the aquaculture groove. The bottom of the return pipe extends into the aquaculture box, a water outlet of the return pipe is close to the upper end of the inclined plate, a residual feed collector is arranged at the position, close to the lower end face of the inclined plate, of the bottom of the aquaculture box, a residual feed gathering box is fixedly connected with the bottom of the residual feed collector, a drain valve is arranged at the bottom of the residual feed gathering box, and aquaculture media are contained in the aquaculture groove. The circulating water symbiotic aquaculture device for the aquatic animals and plants is used for culturing fishes and cultivating aquatic vegetable.
