Role of Allelomimesis of Individuals in Fish School in Collective Evasion of Predator Attacking
A simulation model of collective motion of a fish group was presented to investigate the role of the allelomimetic action of fish individual in schooling behaviors and in collective evasion of predator attacking.Allelomimesis, doing what your neighbors do, is considered as the essential tactic of decision-making by which coherent collective behaviors such as schooling are generated. To simulate a fish schooling behavior in various situations by a single model, we assumed that a fish individual can make three kinds of actions simultaneously, allelomimetic action, avoiding collisions with neighbors and evasion of predator, and it is determined depending on the situation what action each individual gives priority over the other actions. We took account of the effect of energy consumption on the actions.We investigated using the present model how and to what extent fish individuals mimic their neighbors in case of no predator so that the fish group shows good schooling behaviors. The main purpose of the present modeling is to investigate how much each individual pays attention to predator besides neighboring fishes in order to evade predators attacking without straying from the school.
