We performed numerical simulation to investigate the effect of noisy prey dynamics on predator group chase efficiency. For direct interpretation, the chase efficiency is defined as the average number of predators within the sighting radius of a prey at steady state. It is widely believed that random trajectories cause a higher probability of survival for preys. Our results however challenge such conclusion in the case of group chase wherein we observe a stochastic resonance effect with higher chase efficiency at some noise intensity level. A phenomenological model captures the numerical data as a competing effect of the tendency of preys and predators to form into clusters.
