Examine the underlying behavioral mechanisms and local interaction rules that generate cohesive schooling in fish.
Constructed a computer simulation treating individual fish speed and direction as stochastic variables dependent on the heading and position of nearby neighbors.
Modeled three behavioral interactions—approach, avoidance, and parallel orientation—through repeated random number generation across varied parameter combinations.
Unified group movements emerged in the absence of a designated leader and without individuals having global awareness of the entire school.
Cohesive schooling required two core individual behaviors: approach movement to facilitate aggregation and parallel orientation to maintain aligned group travel.
Varying model parameter combinations produced a wide diversity of dynamic movement patterns in the simulated fish schools.
