Fish swimming ability measuring device

The invention relates to the technical field of water conservancy projects, in particular to a fish swimming capacity measuring device. Comprising a fish swimming assembly, a water flow circulation assembly and a behavior observation assembly, and the fish swimming assembly is used for providing a target swimming environment for fishes; the water flow circulating assembly is connected with the water inlet and the water outlet of the fish swimming assembly and used for providing circulating water flow for the fish swimming assembly; the behavior observation assembly is installed above the fish swimming assembly and used for observing the swimming behavior of the fish, analyzing the swimming behavior and determining the swimming ability of the fish in the target swimming environment. The fish swimming ability measuring device can measure the swimming ability of the fish in the target swimming environment, so that a scientific and reasonable fish passing facility can be designed according to the measured swimmin
