21 fish feed samples were acquired commercially in UAE markets. Their ash and moisture contents were found to be 1.96% - 12.49% and 3.22% - 9.59%, respectively. The mineral content of the ash of 7 products was determined by WD-XRF. 13 products were analyzed for MP contamination and showed an MP count of 0.7 - 9 particles per gram. The MP concentration in the fish feed products showed no correlation with the price of the products.
