• Beddington-DeAngelis functional response
• Stochastic perturbation
• Moment boundedness
• Global attractivity

Some dynamical properties of a stochastic non-autonomous predator-prey system with Beddington-DeAngelis functional response are studied. Firstly, we show the existence, the uniqueness and the positivity of the solution. Secondly, we study the boundedness of moments and the upper-growth rate of the solution. Then we investigate the global attractivity of the system. Finally we introduce some figures to illustrate our main results.
