Abstract
There are many kinds of swimming mode in the fish world, and we investigated two of them, used by cyprinids and bulltrout. In this paper we track the locomotion locus by marks in different flow velocity from 0.2 m°s−1 to 0.8 m°s−1. By fit the data above we could find out the locomotion mechanism of the two kinds of fish and generate a mathematical model of fish kinematics. The cyprinid fish has a greater oscillation period and amplitude compared with the bulltrout, and the bulltrout changes velocity mainly by controlling frequency of oscillation.
