| Abstract: | Nutritional components in the muscle of Silurus soldatovi were analyzed with routine methods. The results showed that contents of crude protein, crude fat and moisure in muscles were 16.47%, 2.36% and 79.94%, respectively. In muscles, the total content of 17 common amino acids in muscle was 15.74%, the content of 8 essential amino acids accorded with the FAO/WHO standard ftmdamentally. According to nutritional evaluation in amino score （AAS） and A/E, the first limited amino acids were （Met ＋Cys）. The content of polyunsaturated fatty acid （PUFA） in fatty acids was 23.6%, higher than that in other economic fishes. It was concluded that it was one of freshwater fishes with better nutritive value. |
