The specific gravity, refractive index and viscosity co-efficients were (0.93 ± 0.03 and 0.91± 0.03 at 30C), (1.76 ± 0.21 and 1.34 ± 0.22 at 30C) and (438.43 ± 2.5 and 411.34 ± 1.2) for C. striatus and C. marulius, respectively. Besides, the lipids of both fish showed significant results in case of chemical characterization. On the contrary, C. striatus and C. marulius contained expected amount of carbohydrate, protein, lipid and cholesterol. The percentages of moisture, dry matter and ash were found in fair amounts. Furthermore, the minerals of C. striatus such as calcium and magnesium contents were higher but iron and zinc contents were lower than C. marulius. But, the percentages of lead, mercury and chromium of both fish were precisely in traces amounts. The fatty acids in C. striatus and C. marulius were identified respectively; lauric acid (2.73 and 5.55 %), palmitic acid (17.79 and 27.74 %), oleic acid (36.81and 31.35 %), linoleic acid (3.45 and 2.49 %) and stearic acid (25.79 and 21.81%) Keywords : C. striatus; C. marulius, lipids, fatty acids, nutrients
