| Abstract | ||
| The objective of the current study involved determination chemical composition (including lipid, protein ash, moisture and glycogen) in four fish species from Tigris River in North of Iraq. The chemical analysis revealed that the lipids in muscles of four fish species Carassius carassius, Mastacembleus mastacembleus, Barbas luteus and Silurus triostegus were 8.573 ±0.841 %, 7.715±0.736 %, 8.532± 0.685 %, and 14.650±0.554 % respectively. Proteins content in Carassius carassius, Mastacembleus mastacembleus, Barbas luteus and Silurus triostegus were 310.4 ± 3.649 mg/g, 380.5 ± 2.530 mg/g, 305.1 ± 1.800 mg/g and 321.7 ± 3.587 mg/g of the fresh weight, respectively. The study also shows that ash content and moisture ranged from 1.55± 0.078and 2.99± 0.363%, 76.05± 0.540 and 80.73± 0.147% of the fresh weight, correspondingly. The concentrations of protein in the fishes were significantly different among the species. Concentration of protein was the highest in muscle of Mastacembleus mastacembleus and lowest in the muscle of Barbas luteus. The highest concentrations of glycogen was found in the Carassius carassius among the four species (p<0.001). | ||
