TY - JOUR ID - Takagi_04 L3 - citeulike-article-id:5100583 N2 - We investigated the validity of a mathematical model to describe fish schooling behaviour towards a simple set-net model. We apply a model considered to be "an autonomous decentralized system" and based on Newton's equation of motion. It includes the parameter M, which indicates "the quantity of information exchange" (i.e. the number of neighbours that affect an individual's behaviour) and strongly affects fish school size and schooling behaviour in an enclosed space.
