[ Method] With Si niperca chuatsi as the control , the protein content , water content , fat content , fatty acid content and the amino acid in the muscle of S . kneri and S . scherzri were analyzed . [ Result] The protein content in the muscle of S . kneri and S . scherzri were 18 .71 % and 18 .99 % , resp . , and the water content were 76 .06 % and 76 .16 % , resp . Though the fat content in muscle was not high , their unsaturated fatty acid content was higher , being above 20 % , especially they had abundant EPA and DHA , and the unsaturated fatty acid content was higher than saturatedfatty acid content . The protein content was rich and the amino acid content was high in the muscle , which could supply body essential amino acid conten
