Adaptive Feeding Device and Method for Swimming Fish Based on Photo-acoustic Coupling Technology

An adaptive feeding device for swimming fish based on photo-acoustic coupling technology, comprising:

• a recirculating aquaculture pond, a recirculating water treatment system, a high-definition waterproof camera, a feeding machine having a feeding port, and a LED supplement light, a PLC, a digital signal processor, a display, and a hydrophone;
• wherein the recirculating water treatment system is installed outside the recirculating aquaculture pond;
• the high-definition waterproof camera is installed directly above the recirculating aquaculture pond, and the high-definition waterproof camera is connected to an input end of the digital signal processor;
• the feeding machine is installed directly above the recirculating aquaculture pond, and there is the feeding port of the feeding machine at both sides of the high-definition waterproof camera;
• there are several LED supplementary lights under the feeding machine;
• the feeding machine is connected to an output end of the PLC;
• the hydrophone is secured inside the recirculating aquaculture pond and connected to the input end of the digital signal processor;
• an output end of the digital signal processor is connected to the input end of the PLC and the display at the same time.
