Survey of some Chemical Compositions and Fatty Acids in Cultured Common Carp (Cyprinus carpio) and Grass Carp (Ctenopharyngodon idella), Noshahr, Iran

Abstract

3 Abstract: Ecological studies have found a negative correlation between the risk of developing heart diseases and fish consumption because of their long chain omega-3 fatty acids. In this study to determine of som e chemical compounds (proteins, lipids, moisture and ash) and fatty acids were determined for two cultured species, common Carp (Cyprinus carpio) and Grass carp (Ctenopharyngodon idella). Results of this study showed amount of saturated fatty acids (SFA) in common carp and Grass carp were 35.21 ± 2.19% and 27.18 ± 2.63% respectively, SFA in common carp was higher compared to grass carp (P 0.05). This study showed in grass carp PUFA was higher than SFA, while in common Carp SFA was higher than PUFA (P 0.05).
