%X In this paper, measurements were made on the ratios of flesh in whole body and the biochemical composition, energy and amino acids of muscle in the F2 generations of Aristichthys nobilis Black-spot and A. nobilis White-spot, which were newly breeding fishes originally living in the four major Chinese carps breeding site in Changsha. Samples of 6 individuals of each group were collected. The ratios of flesh in whole body of A. nobilis Black-spot and A. nobilis White-spot were 77.47% and 77.53%, respectively. The biochemical compositions (%, wet) of A. nobilis Black-spot and A. nobilis White-spot were that: the moistures of muscle were 80.56% and 79.38%, protein 17.01% and 79.38%, fat 17.01% and 17.67%, ash 1.25% and 1.35%, non-nitrogen extract 0.37% and 0.40%, the content of energy were 4.43kJ/g and 4.72kJ/g, while as E/P were 26.04kJ/g and 26.71kJ/g, respectively. Seventeen common amino acids and nine essential amino acids for human were found in the composition of amino acids of muscle. In the dry sample of A. nobilis Black-spot, the total content of amino acids, which was 81.32g/100g, the content and ratio of essential amino acids, which were 40.05g/100g and 49.25%, respectively, the content and ratial of 4 kinds delicious amino acids, which were 29.13g/100g and 35.82%, respectively, were lower than that of A. nobilis White-spot, with 86.63g/100g, 40.05g/100g, 48.53%, 31.57g/100g and 36.44%, respectively, Whereas the percentages of essential amino acids in total amino acids (49.25%) and essential amino acids to non-essential amino acids (0.97) were higher than that of A. nobilis White-spot, with 48.53% and 0.94, respectively, however all the differences mentioned above were not significant (P>0.05); According to nutrition evaluation i.e., the amino acids score (AAS) and chemical score (CS)], the limited amino acid of A. nobilis Black-spot and A. nobilis White-spot were valine, leucine and threonine, while the first limited amino acid was valine, with leucine as the first limited amino acid of A. nobilis Black-spot on the basis of AAS; The essential amino acids gram to total nitrogen gram (E/TN) and the essential amino acids index of A. nobilis Black-spot were lower than that of A. nobilis White-spot, with 2.62, 77.98 and 2.67, 79.6, respectively (P> 0.05), but both of them are higher than that of A. nobilis from other producing areas, indicating that: both A. nobilis Black-spot and A. nobilis White-spot, the new kinds of freshwater fishes with better nutritive value and raising value, deserving of exploitation and utilization and have a good economic prospects.
