Feeding: the fodder is discharged back by the feed bin bottom, gets into underwater feeding pipe 61, and under the rivers drive of hydraulic drive ware drive, gets into the feeding distributor box 62 that is located drain pipe 3 intracavity, redistributes for a plurality of feeding bifurcated pipes 63, through throwing the material export and get into in the lower floor's pond, accomplish the work of throwing the material. By means of underwater monitoring (underwater camera), the degree of fish body satiety is judged according to the gathering degree of fish swarms and residual baits near the underwater feeding outlet, so that a switch (feeding valve in the above) of the feeding machine is controlled.

3. Fish feeding: the fish can be fed in and out by the aid of the upper and lower fish outlet pipes. When fish feeding operation is needed, the fish outlet pipes are respectively connected to the outlets of the pump pipes of the fish suction pump, fish are sucked out of the original fish pond under the hydraulic driving of the fish suction pump, and are conveyed to the first culture pond unit 101 and/or the second culture pond unit 102 through the fish outlet pipes and are discharged by the corresponding fish collectors. The pipeline at the front end of the fish outlet pipe is provided with an infrared fish counting device, operation is carried out according to the fish inlet amount of each layer of culture pond unit, after one layer is put in, the fish outlet pipe is switched to carry out fish inlet work of the other layer of culture pond unit.

4. Fish discharging: the fish outlet pipe is connected with a pump pipe of a fish suction pump, the water of the culture pond unit needing to be discharged is drained to a proper water level to enable the fish to be gathered, the fish suction pump is started, the fish enters from the fish collector, and the fish is conveyed out of the fish culture pond through the fish outlet pipe.

5. And (3) dead fish collection: when dead fish are collected, the high-pressure air pump is started, the air is transmitted to the bottom of the fish outlet pipe through the air supply pipe, the dead fish are sucked into the fish collector under the action of air lifting, and then the dead fish are discharged from the fish pond through the fish outlet pipe and flow into the dead fish collecting box (device), so that the dead fish collecting work is completed.

6. An air chamber 7: in order to supplement the air required by the air of the swimming bladders for cultivating the fishes, the air chamber 7 is arranged, the air needs to be supplemented periodically, during the work, the air pump is started, enters the air chamber 7 through the air supplementing pipe, and is accumulated at the upper end of the air chamber 7 to form an air chamber, and the cultivated fishes can swim to the air chamber 7 to swallow the air when the air needs to be supplemented.
