  In the present study, the effect of stirring speed and the type of cross linking agent on the size and formation of microencapsulated Silver carp (Hypophthalmichthys molitrix) oil were investigated. The gelatin/gum Arabic was used for encapsulating and the capsules were prepared by complex coacervation. Microcapsules were analyzed by optical microscopy technique and particle size analyzer. Results suggested the use of glutaraldehyde as the cross-linking agent instead of formaldehyde can caused the Microcapsules become spherical shape, smooth surface with no obvious dents and narrower particle size distribution. The average particle sizes were ۵۳۷.۲±۰.۸ μm, ۸۴.۴±۰.۵ μm, ۱۲.۹۸±۰.۴ μm, ۸.۲۴±۰.۵ μm, and ۴±۰.۷ μm at the homogenization stirring speed of ۱۰۰, ۳۰۰, ۵۰۰, ۷۵۰ and ۱۰۰۰ rpm respectively. The best conditions of experiment were with ۲۵% glutaraldehyde at ۱۰۰۰ rpm of stirring speed.
