In this paper,the dynamics behavior of a plankton model in foraging arena were investigated.Firstly,it was proved that there was a unique global positive solution starting from the positive initial value.Then,sufficient conditions for extinction and persistence in mean were obtained by comparison theorem for sto-chastic differential equation.In addition,it was proved that there existed a unique ergodic stationary distribu-tion.Finally,the theoretical results were verified by numerical simulation.
