It is well known that fishbone oscillations occur in the tokamak plasma at high {epsilon}{beta}p and in the presence of large hot trapped particle population. We adopt and extend the formalism of Chen et al. to analyze the trapped hot ion induced fishbones in the ITER-type plasma. Using the familiar assumptions like large assumptions like large aspect ratio and low beta, we considered the stability of the trapped-ion induced internal kink mode in the presence of alphas and one other species of hot ions.
