What is Zebrafish Shoaling?
Shoaling is the natural tendency of zebrafish to form cohesive social groups. Shoaling behavior provides a robust readout of social motivation, anxiety, and sensory integration. Disrupted shoaling is observed in genetic models of autism spectrum disorder, schizophrenia, and after anxiogenic drug treatment.
ConductVision tracks multiple zebrafish simultaneously with markerless identity preservation, computing nearest-neighbor distance, group polarization, and cohesion metrics frame by frame. The software outputs individual and group-level statistics for pharmacological screening and social behavior genetics studies.
