Abstract: Contents of moisture, crude protein, lipid and crude ash were analysed in different parts of muscle, carapace, calipesh and fatty block of juvenile Chinese soft-shelled turtle (weight: 11.5- 18.0g), one-year old Chinese soft-shelled turtle (weight: 100.0- 125.5g), two-year old Chinese soft-shelled turtle (weight:220.0-263.0g) and three-year old Chinese soft-shelled turtle (weight: 450.0-480.0g), and so was the composition of fatty acids. The contents of crude protein in muscle, calipesh and carapace ranged from 18.33% to 24.74%. The contents of lipid in muscle、 calipash and carapace were fairiy low. The fatty acids in muscle contaned 32.39% highunsaturated fatty acids, among which EPA (C20:5 Eicosapentaenoil acid) was about 7% and DHA (C22:6 Docosaheraenoic acid) about 8% of tatal fatty acids.
