Abstract:

The muscle nutritional components of Channa argus and golden Channa argus were compared to provide reliable data for the nutritional value research of golden C. argus. The conventional nutrient components, amino acids and fatty acids in the muscle of C. argus and golden C. argus were determined and analyzed by using the national standard test method, and SPSS16.0 was used for studying the results. The results showed that the content of crude protein, crude fat and ash between C. argus and golden C. argus were not significantly different (P>0.05), while the moisture content of the golden C. argus was significantly higher than that of C. argus (P<0.05). Among the 17 amino acids detected in the 2 species of C. argus, glutamic acid (Glu) content was the highest, cysteine (Cys) content was the lowest, and the ratios of EAA/TAA and EAA/NEAA were 39.29%-39.66% and 77.20%-79.36% respectively. There was no significant difference in the content of saturated fatty acid, monounsaturated fatty acid and polyunsaturated fatty acid between C. argus and golden C. argus (P>0.05), as well as the content of DHA and EPA. The content of oleic acid and linoleic acid of golden C. argus were significantly higher than those of C. argus. The above results indicate that golden C. argus is a kind of fish with high nutritional value as well as ornamental value, and has good prospects for development and utilization.
