Abstract: Currently, hydraulic project development requires assessment of environment implications. Understanding fish shape, swimming ability and energy cost of the fish during swimming will helpful to design fish-friendliness hydraulic structure. In this paper, a self-propulsion of 3D-fish model has been developed. The interaction of the fish and fluid are taken into account. The fish swimming velocity, torques andenergy expending during swimming with different shapes are calculated. The fish swimming ability with different beat frequency (1. 43, 0. 94 and 0. 64 Hz) are also analyzed. The study has following objectives: to determine the mechanisms of fish swimming, fish swimming velocity and analyses the energy of the fish expended consider the fish length, body shapes, tail beat frequency.
