The invention provides equipment for improving the live transportation survival rate of edgy fishes. The equipment comprises a tank (1), a plastic cover film (2) matched with the tank (1), and a water purifier (3). The water purifier (3) comprises a water distribution layer (4), an ice cube layer (5), a filter cotton layer (6), an active carbon layer (7), and a water storage layer (8), wherein the above layers are arranged from top to bottom. The lower part of the tank (1) is provided with a water inlet pipe (9) to be connected with the water distribution layer (4) via the water purifier. The upper part of the tank (1) is provided with a provided with a water outlet pipe (10) to be connected with the water storage layer (8) via the water purifier. The water outlet pipe (10) of the water purifier is provided with an airlift pump interface (11). According to the technical scheme of the invention, a water quality purification method for water in transportation facilities is provided for aquaculture practitioners during the transportation process based on the physiological characteristics of saury and shad. In this way, the collision injured risk of fishes when frightened is reduced, and the water quality of the transportation water is improved. Meanwhile, the metabolites of fishes are timely eliminated, so that the stress reactions of edgy fishes, such as saury and shad, are reduced. Moreover, the risk of mechanical traumas and the risk of physiological endogenous injuries during the transportation process are reduced. The live transportation survival rate of fishes is improved. Furthermore, the temporary-rearing or cultivation survival rate of fishes after the transportation process is improved.
