The aims of this study were to characterize the lipids isolated from Pangasius pangasius and Pangasius sutchi and to analyze the nutrient contents of these fishes. The specific gravity, refractive index and viscosity co-efficient were (0.97 ± 0.01 and 0.94 ± 0.02 at 30°C), (4.88 ± 0.25 and 5.49 ± 0.30 at 30°C) and (448.96 ± 2.5 and 421.76 ± 2.1) for P. pangasius and P. sutchi, respectively. Likewise, Chemical characterization of lipids of both fishes has shown the significance results. Besides, P. pangasius and P. sutchi contained carbohydrate, protein, cholesterol and lipids of 1.89 ± 0.35% and 0.75 ± 0.11%, 35 ± 2.1% and 38.37 ± 2.5%, 17.46 ± 1.15% and 13.79 ± 0.37%, and 10.01 ± 1.11% and 6.16 ± 0.54%, consecutively. The percentages of moisture, dry matter and ash were found in fair amounts. Furthermore, the minerals of P. pangasius such as calcium, phosphorus and zinc contents were lower and iron contents were higher than P. sutchi. The fatty acids profile of P. pangasius and P. sutchi were identified as lauric acid (13.36 and 4.26% ), palmitic acid (26.15 and 29.32%), oleic acid (46.07 and 59.16%) and stearic acid (14.40 and 7.24%), respectively.
