A simulation study on fish behavior affected by obstacles

In this paper, a mathematical model is proposed to describe various behavior patterns adapted to different environments around a fish school. In this model each individual fish behaves autonomously; and at the same time a specific order of the school is formed based on the environmental effect and the information exchange among other individuals. Simulations are carried out for the case where the school is affected by a square obstacle. Especially, the relationship between the order of the school and the state of each individual is investigated
