英文摘要：

This paper introduces the lateral line system, which is a system of sensory organs in fish, used to detect the features of water movement. In order to study the physiological mechanism of the lateral line system, the capability of the lateral line system to detect water velocity, acceleration, pressure, and the source of vibration was analyzed. Experiments were conducted to study the effects of water velocity, turbulence, and shear stress on the behaviors of fish, in order to explore the response patterns of fish. The fish injuries caused by turbulence and shear stress are also discussed in this paper. In addition, the SVP hypothesis, a new method to study the behaviors of fish in response to the hydrodynamic environment, is introduced. Based on the description and analysis of the methods used to determine the relationship between fish behaviors and water movement, we draw the conclusion that to study the fish behaviors in response to the hydrodynamic environment, it is essential to work out an appropriate metric for coupling the hydrodynamic factors and the characteristics of water movement.
