Abstract: Analysis of the nutrient content of wild and farmed Channa argus muscle tissue showed that crude fat content in wild Channa argus was significantly lower than that in the farmed variety (p < 0.05). However, the content of n-3 polyunsaturated fatty acids (PUFA) and c22:6 (DHA) in the muscle of wild Channa argus was higher than that in the farmed Channa argus, where the ratio of n-3/n-6 of the two samples was 1.21 and 0.65, respectively. A total of 17 amino acids were detected in the muscles of wild and farmed Channa argus, where the content of total amino acids, delicious amino acids, and essential amino acids in the farmed Channa argus was higher than that in the wild variety. The ratio of essential to total amino acids (EAA/TAA) in the muscles of wild and farmed Channa argus was 42.66% and 42.28%, respectively. The ratios of essential to non-essential amino acids were 74.40% and 73.26%, respectively, which were higher than the ideal protein patterns recommended by Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO). The essential amino acid index of wild and farmed Channa argus muscles was 63.48 and 70.82, respectively. In both samples, potassium showed the highest mineral content, whereas trace elements were significantly higher in muscles of the farmed variety than wild Channa argus (p < 0.05). In conclusion, the farmed Channa argus fed with low-value, wild trash-fish shows good development prospects for .
