The aim of this study was to assess protein, lipid, carbohydrate, fiber, ash, and moisture in two species of fishes, Aspius vorax and Carasobarbus luteus, in 2011. Fifteen samples of Carasobarbus luteus and 12 samples of Aspius vorax were collected from the Karkheh River. Mean levels of protein, lipid, ash, moisture in Carasobarbus luteus were 17.19±0.36, 3.23±0.15, 1.28±0.07 and %74.03±0.32, respectively. Similarly, the same chemical contents in Aspius vorax were 18.10±0.36, 2.60±0.20, 1.18±0.09 and %72.10±0.40, respectively. Level of moisture in muscle of two species of Aspius vorax and Carasobarbus luteus were significancantly different (P<0.05), but no significant difference was noticed for protein, ash and lipid (P>0.05). However, Protein in muscle tissue of Aspius vorax was more than Carasobarbus luteus, but lipid, moisture and ash in muscle tissue of Carasobarbus luteus was more than Aspius vorax. Therefore, the results showed that, in terms of animal protein, Aspius vorax is more appropriate compared to Carasobarbus luteus.
