Bardeen proposed a gravitationally collapsing magnetic monopole black hole solution which is free of singularity. In this article, we have studied the size and shape of the rotating Bardeen blackhole shadow in presence of perfect fluid dark matter. we have discussed how the parameters such a spin, magnetic monopole charge and influence of dark matter affects the shadow of our blackhole. The apparent shape of the blackhole was studied by using two observables, the radius Rs and the distortion parameter R_s. Further the blackhole emission rate is also studied, we found out that for rotating Bardeen in PFDM ,For a constant monopole charge, the emission rate increases with increase in dark matter parameter, the emission rate decreases with increase in magnetic charge and spin.

    Ray-traced images of a rotating Bardeen black hole in perfect-fluid dark matter show D-shaped shadows, Doppler-brightened crescents, and redshift patterns that shift with spin, magnetic charge, and dark matter strength.
