A swarm of plankton such as Daphnia can provide a natural source of electric noise needed for the mechanism of stochastic resonances (SR). The swarm noise as OU noise produced by incoherent Daphnia activity was modeled. The fast geometric decay of the noise intensity D(R) and of the dipole signal amplitude A(r) restricts the spatial region of SR to a narrow band around the swarm boundary. The spatial distribution of the average phase locking period for the subthreshold signals produced by the swarm was calculated.
