The paper describes a method to construct the information transfer network of fish school based on video data and transfer entropy. We first obtain the collective behavior video of zebra fish in the experi- ments and get the position and velocity of each individual using computer vision tracking method, and then calculate the transfer entropy between any two individuals to determine the information transfer relationship, finally build the informa- tion transfer network. The relationship between the number of information exchange and the speed of information transfer is revealed and the frequent substructures are detected through network analysis. We provide a new approach for fish school information transfer research by modeling the information transfer
