Comparison of Nutrient Composition in Muscles of Wild and Farmed Yellowcheek Carp

Abstract

Abstract: A comparative analysis on the nutrient composition of muscles of wild and farmed yellowcheek carp was carried out in the present study. The results showed that wild and farmed yellowcheek carp muscles did not significantly differ in water content (P = 0.07779 ＞ 0.05). Wild yellowcheek carp was significantly higher in the contents of crude protein and ash than farmed yellowcheek carp (P= 0.00115, 0.00415 ＜ 0.05), while crude fat content in farmed yellowcheek carp was significantly higher than in wild yellowcheek carp (P= 0.000215 ＜ 0.05). The essential amino acid index of farmed yellowcheek carp muscle was 94.16 compared with 66.03 for mild yellowcheek carp muscle. Both values meet the FAO/WHO requirements. The total percentage of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in wild and farmed yellowcheek carp muscles represented 4.25% and 4.8% of total fatty acids, respectively. Taken collectively, the results obtained suggest that farmed yellowcheek carp is superior to wild yellowcheek carp in terms of both amino acid composition and total content of EPA and DHA, while wild yellowcheek carp is superior in terms of protein content and n-3/n-6 PUFA ratio.

Key words: yellowcheek carp, muscle, nutritional quality
