Abstract

The burst speed is the highest swimming speed of fish. Fish can migrate through fishways, when the maximum velocity in fishways is smaller than the burst speed. Therefore it is necessary to understand the burst speed of fish. In this study, an investigation on the burst speed of Zacco platypus under the condition that the body length and flow velocity are changed was conducted. The results show the swimming speed increases rapidly after starting swimming and acceleration decreases gradually. Finally, the swimming speed reaches to the burst speed. The burst speed divided by the body length decreases with an increase of the body length and increases with an increase of the flow velocity. The burst speed is generally known as a value ten times of the body length of fish. However, it was found that the burst speed of Zacco platypus is up to 30 times or more of the body length from the present experiments.
