【 摘 要 】

This study analyzed the chemical composition of the dorsal muscle tissue of Hypophthalmus edentatus, in particular, fatty acids of the lipidic fraction, and its relationship with the biological variables and the capture period. The average values for moisture, ash, protein and total lipids were 63.15, 1.11, 14.27 and 17.24%, respectively. In the lipidic fraction, 35 fatty acids were identified, the most abundant being: 16:0, 18:1omega9, 18:0, 16:1omega7, 18:3omega3, DHA and EPA. The totals of respectively saturated, monounsaturated and polyunsaturated fatty acids were 41.15, 35.30 and 23.88%. The PUFA/SFA ratio was equal to 0.68 and the omega3/ omega6 ratio equal to 1.98. The PCA demonstrated that the long chain PUFAs contributed positively to the formation of the first axis. The CCA showed some effects of the biological factors (weight, reproductive cycle, sex) and the capture period on the variation of total lipids and some fatty acids.
