• An aim of this paper is to compare a proposed simple model for the target strength (TS) of swimbladder fish with existing models. Through the comparison we verify the validity of the simple model. Particularly, two more sophisticated models are compared with: namely, the exactly solvable soft spheriod model and the ray-Kirchhoff approximate model. The comparisons show that at high frequencies or intermediate frequencies the present model can yield results in reasonable agreement with that from the other two models respectively. Indirect comparison with experimental data is also briefly made. It is shown that the model may facilitate general calculation of the target strength of swimbladder fish.
