This research aims to understand how schooling fish generate cohesive movement patterns through self-organized dynamics of aggregation and dispersion.
Experimental data was collected in a ring-shaped tank with varying group sizes.
Group cohesion, aggregation-dispersion scale, and directional fluctuations were measured.
A data-driven dynamical model evaluated attraction and alignment interactions among fish.
Schooling fish maintain optimal cohesion by alternating between aggregation and dispersion movements.
Duration of each movement type remains constant regardless of group size, but coordinated movement duration increases with group size up to 20 fish, then decreases.
Different interaction parameters create various collective motion states, such as milling and ordered states.
