The present study was carried out to characterize the lipids isolated from Clarias batrachus and to analyze the nutrient contents of these fishes. The specific gravity (0.87 at 30°C), refractive index (5.19 at 30°C), co-efficient of viscosity (448.26) were measured. Besides, the quantitative analysis of acid value (1.93), percent of free fatty acids (0.97%), saponification value (179.88), saponification equivalent (311.87), iodine value (53.93), peroxide value (43.63), ester value (177.95), unsaponificable matter (1.96%), acetyl value (16.09), reichert-meissel value (3.13), cholesterol (15.46%) were evaluated. Likewise, carbohydrate, protein and lipids were 6.26, 14.14 and 6.91% respectively. Moisture contents were 78% but ashes were (0.1%). Further, the mineral studied as calcium, phosphorus and C. batrachus was identified as lauric acid (2.6%), palmitic acid (37.41%), oleic acid (49.1%) and stearic acid (3.6%) arachidic acid (3.04%) and behanic acid (4.21%) respectively.
