Fish schooling behavior properties and 1/f fluctuation

Abstract

We describe an experimental study on dynamics of fish schooling behaviors. There are very few paper about quantitative and practical information of fish school behavior properties. In order to obtain information of dynamical fish school behaviors, experiments with Japanese dace Tribolodon hakonensis and Ayu Plecoglossus altivelis were carried out. We calculated time series data of fish school radius from individual positon coordinate data. We confirmed that fish school radius fluctuation was 1/ƒ fluctuation.
