The swimming ability of fish is one of the important parameters in fishway engineering design and the key basis for successful fish migration in fishway. The induced velocity, critical velocity and burst velocity of Lateolabrax japonicus in Minjiang River Basin of Fujian Province are studied. The experiment is conducted in an open channel glass flume by using velocity gradient method. The characteristic velocity of lateolabrax japonicus in Minjiang River Basin is obtained for the first time, i.e. the mean values of relative induced velocity, relative critical velocity and relative burst velocity are 0.88, 2.29 and 2.65 BL/s（BL：Body length）, respectively. This study reveals the difference between lateolabrax japonicus in Minjiang River Basin and Yangtze River Basin. The relative critical velocity of the lateolabrax japonicus in the Minjiang River Basin is slightly higher than that in the Yangtze River Basin, and the relative burst velocity of the lateolabrax japonicus in the Minjiang River Basin is obviously higher than that in the Yangtze River Basin. The formula of induced velocity is improved based on the experimental data. It is firstly proposed that the total induced velocity be divided into the base part and the body length increasing part, and the basic induction velocity of Minjiang lateolabrax japonicus is 0.002 3 m/s..
