An individual based model of fish school reactions: predicting antipredator behaviour as observed in nature
An object‐orientated, two‐dimensional, cellular automata (CA) model is developed to describe and predict the schooling behaviour of fish in general, with Norwegian spring‐spawning herring, Clupea harengus L., being used as a case study. The CA model is applied to visualize internal school dynamics b...
