Abstract:The ratio of muscle in whole body and the composition of fatty acids and mineral elements of muscle in Tor (Foliter) brevifilis brevifilis were determined and analyzed on the basis of 18 specimens collected respectively from the Qingshui River and the Duliu River in Guizhou, China in October, 2004. The results showed that the ratio of muscle in whole body averaged 66.91%. There were 14 fatty acids, including 5 saturated and 9 unsaturated fatty acids (with an average total content of 39.49% and 58.83% respectively). A total of 9 mineral elements were determined in the muscle. Of the 9 mineral elements, the range of average contents of macroelements including Ca, P, k, Na and Mg was 116.35 mg/100 g1313.33 mg/100 g and that of microelements including Cu, Zn, Fe and Mn was 0.19 mg/100 g5.20 mg/100 g. Ca : P averaged 1 : 4.31. The correlation analysis demonstrated that the ratio of muscle in whole body, ratio of sex gland in whole body, and the contents of C18:2, C20:1, P and Cu increased significantly along its growth of body respectively, but the contents of C20:5, K, Mg and Mn significantly decreased during its growth. t-test and correlation analysis showed that there were significant differences in the contents of C20:5, Mg, Mn, Zn and Fe in the muscle between the specimens collected respectively from the Qingshui River and the Duliu River, which likely resulted from the difference of aquatic environment between the two rivers.
