This study has about to compare the protein, fat, carbohydrate, fiber, ash and humidity between Oreochromis niloticus (importfish) and Oncorhynchus mykiss (farmed trout).The samples were collected from Ahwaz bazars by determining their entry origin. Data analysis was carried out using the SPSS17 software, Duncan's test and the one-way variance analysis (ANOVA). The significant difference was determined level of 95% (P=0.05). The level of carbohydrate in the muscle of both studied fish was 2.72±1.59 and the rate of fiber was non-measurable and zero. The maximum rate of protein, fat and ash were respectively 22.14, 6.76, 3.8g per 100g dry weight. The maximum rate of the humidity was also 75.6%. The maximum amount of protein and fat was seen in farmed trout (Oncorhynchus mykiss) and the maximum rate of ash and humidity was observed in Oreochromis niloticus. The rate of ash and protein didn't have a significant difference between two species (P≥0.05) but there was a significant difference between the rate of humidity and the amount of fat (p<0.05).
