The effect of storage on the nutritional composition of pelleted fish feed as well as the antinutritional components was studied using two commercially formulated feeds: Coppens (exotic) and vital (local) feeds. Feed samples were purchased and monitored in storage at ambient temperature forth nightly for 6 weeks using standard procedures. Result obtained showed reduction in feed quality with increasing storage period with significant difference (P > 0.05) in all nutrient components (moisture, protein, lipid, ash, crude fibre and nitrogen free extract).There was however no significant difference (P>0.05) between the nutritional components of both feed samples during the storage period. Anti-nutritional components detected in feed samples were oxalate, phytate and tannins with phytate having the highest values in both feed sample.
