A runway type recirculating water aquaculture apparatus for temporary culture of freshwater fish

Abstract

This utility model relates to the field of aquaculture equipment technology, and discloses a racetrack-type recirculating aquaculture system for the temporary holding of freshwater fish. It includes an outer shell, with an aquaculture mechanism on the inner wall of the shell for efficient aquaculture. The aquaculture mechanism includes an aquaculture pond located on the right side of the inner wall of the shell. A water collection trough is located in the middle of the inner wall of the shell. A circulation component is located on the left side of the inner wall of the aquaculture pond. A cleaning component is located on the inner wall of the water collection trough. A sludge collection component is located on the inner wall of the aquaculture pond. An oxygenation component is located on the right side of the shell. A drainage component is located on the left side of the cleaning component. In this utility model, two circulation pumps lift the aquaculture water to the aquaculture pond. A bag filter at the bottom of the circulation pipe performs preliminary filtration of the water. When the water in the clear water trough reaches a certain height, it flows back to the aquaculture pond along the drainage pipe. This system has a small footprint, low energy consumption, and strong adaptability.
