The study was conducted with a view to assess the nutritional composition of freshwater carps Ctenopharyngodon idella and Hypophthalmichthys molitrix in Cauvery Delta. Fish samples were chemically analyzed for moisture, carbohydrate, protein, lipid and ash. When chemical composition of two fish species collected was compared, the differences were substantial. Considering proximate composition highest content of moisture (76.98%) was recorded in Hypophthalmichthys molitrix than Ctenopharyngodon idella (72.60%). Lipid content was slightly more in Ctenopharyngodon idella (2.43%) than Hypophthalmichthys molitrix (2.21%). Eminent levels of protein and lipid were observed in Ctenopharyngodon idella while lower in Hypophthalmichthys molitrix. The percentages of protein content ranged between 15.34% in Hypophthalmichthys molitrix to 17.53% in Ctenopharyngodon idella, which is quite high. Carbohydrate content present in Hypophthalmichthys molitrix was recorded 1.08% which is less than Ctenopharyngodon idella where it was recorded 1.13%. The range of ash content from 1.18 - 1.38% gave an indication that the fish sample may be good source of minerals such as calcium, potassium, zinc, iron and magnesium.
