Abstract：Otter board is one of the most important component fishing gears for expanding the mouth of trawl net in horizontal direction. The hydrodynamic characteristic of otter board has a directly effect on fish efficiency. This paper deals with the research on hydrodynamic characteristics of 4 kinds of otter board，rectangular flat, vertical cambered plate, vertical v-shape cambered plate and biplane-type otter board. To improve and optimize the otter boards, the paper summarizes several acting factors of hydrodynamic characteristics. And it clarifies the problems and future development of otter boards in our country from three aspects including airfoil theory, model test and computational fluid dynamics，

Key words：otter board；hydrodynamic characteristic；influence factors；problem and prospect
