The authors investigate a periodic Watt-type predator-prey system with impulsive perturbations at fixed moments of time. Sufficient conditions for the existence of a periodic solution are proved. The main results are obtained by using the continuation theorem of coincidence degree theory. The uniform persistence of the system is also studied.
