Comparison of protein, fat, ash and dry matter content of common carp, Cyprinus carpio L. and silver carp, Hypophthalmichthys molitrix fillet

Abstract

In this study, protein, fat, ash and dry matter content of common carp and silver carp fillets at different weights were compared. For this purpose, two years old common carp and silver carp were studied at the weights of 500, 700, 1000, 1300 and 1600 g, during the culture period (eight months). After selecting the desired fish, length and weight were measured and then 100 grams of fillet was isolated from the fish and the biochemical composition was evaluated. The results of the present study showed that the average protein, fat, ash and dry matter content were in the common carp fillet, respectively: 10.209±2.106%, 9.429±0.937%, 1.407±0.198%, 21.03±1.62%, and in the silver carp, respectively: 14.187±1.86%, 7.55±1.56%, 1.498±0.2% and 23.149±1.05%. In addition, the results of this study indicate that there is no significant difference between the quality factors of common carp and silver carp in different fish classes (p>0.05). The results showed that fish weight had no effect on fillet quality. The protein, ash, and dry matter contents of common carp fillet are lower than that of silver carp. Meanwhile the fat content in the fillet of common carp was higher than silver carp the results of the present study showed that the fillet composition of these cyprinid species was dependent of their feeding regimes.
