Comparative Study on Body Composition of Two Chinese Carps, Common Carp ( Cyprinus carpio ) and Silver Carp ( Hypophthalmichthys molitrix )

摘要

Fish is influencing almost every niche of human life. It is considered as one of the most importantanimals, on account of its widespread role economically, nutritionally and as a medicinal tool. Intensive researchabout different aspects of fish has been under its way all around the globe. The current study was conductedon two fish species Cyprinus carpio and Hypophthalmichthys molitrix available to consumer in fish marketand hotels at Timergara, District Dir Lower Khyber Pakhtunkhwa Pakistan. This study was designed to evaluatethe body composition of these two widely consumed Chinese carps. For common carp water content, protein(Dry), protein (Wet), Fat (Dry), Fat (Wet), Organic content (Dry), Organic content (Wet), Ash (Dry) and Ash(Wet) ranged (in percentages) from 65.09-67.1, 65.9-66.8, 24.7-25.4, 18.9-19.3, 7.69-8.45, 85.6-86.7, 28.97-29.56,8.98-9.99 and 3.1-3.89 respectively, while for silver carp these constituents ranged from 74.87-76.8, 64.5-68.7,24.89-26.5, 18.89-20.1, 7.89-8.9, 86.7-89.4, 27.6-29.7, 12.38-13.86 and 4.52-4.97 respectively. Results showed thatthese fish are having high nutritive values. The present study also revealed that there is a significant difference(P<0.05) between body composition of the studied fish species. Moreover, variations also exist between thespecimens of the same species for all the constituents.
