Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an automated fishpond fishing device. Background Technology

[0002] With the advancement of technology and the development of aquaculture, recirculating aquaculture systems (RAS) are gradually becoming an important development direction for the aquaculture industry as a highly efficient, environmentally friendly, and controllable modern aquaculture model. This method achieves water resource recycling by constructing a closed ecosystem, reducing dependence on and pollution from the external environment, while simultaneously improving aquaculture efficiency and product quality. The aquaculture pond system is the core area of ​​RAS, used to house and cultivate aquatic organisms. Depending on the species being farmed, the ponds can be designed in various shapes, such as circular, square, or rectangular. To improve wastewater collection and discharge efficiency, most ponds are designed as circular. However, when fishing in circular ponds, conventional fishing nets often create an angle difference with the pond's inner wall, leading to fish leakage. Therefore, we propose an automated fishpond fishing device to solve this problem. Utility Model Content
