The Study and Comparison of Some of Chemical Compositions in Muscle of Three Endemic Species of Cyprinidae from Hor-e-lazim Wetland in Khoozestan Province

The aim of this study was to assess protein, lipid, carbohydrate, ash, and moisture and zinc and iron in three species fish Barbus pectoralis, Carasobarbus luteus and Aspius vorax from Hor-e-lazim wetland Khoozestan Province. 27 Samples were collected of Barbus pectoralis, Carasobarbus luteus and Aspius vorax Hor-e-lazim wetland. Data were analyzed with SPSS18 software in terms of t-test which determine prese or non-presence of the significant difference in level 95 precent (P=0.05). This study between of protein, ash and carbohydrate in muscle of Barbus pectoralis, Carasobarbus luteus and Aspius vorax from Hor-e-lazim wetland dosenot show significance different (P>0.05), but lipid and moisture in three species fish significance different (P<0.05). The highest of protein (17.5±0.62), lipid (3.43±0.2) and carbohydrate (0.61±0.009) in muscle of Barbus pectoralis and the highest of ash (1.56±0.15) and moisture (80.73±0.2) in muscle of Carasobarbus luteus. The lowest of protein (16.23±0.25) and lipid (1.3±0.17) were observed in muscle of Carasobarbus luteus and the lowest ash (1.02±0.072) and moisture (77.43±0.45) were observed in muscle of Barbus pectoralis. Concentration of iron in muscle of Barbus pectoralis, Carasobarbus luteus and Aspius vorax was 10.96±0.25, 10.46±0.28 and 9.73±0.2 mg Kg-1 ww. Concentration of zinc in muscle of Barbus pectoralis, Carasobarbus luteus and Aspius vorax was 11.9±0.36, 12.9±0.36 and 10.93±0.27 mg Kg-1 ww.
