Popis: Total fatty acids (TFA) and different fatty acids contents of the gonads, liver and muscles in male and female Diplodus annularis were studied. The gonadosomatic (GSI) and hepatosomatic index (HIS) present a maximum value in female specimens, respectively 8.48 ± 0.80 and 1.86 ± 0.11. Our results show that TFA are accumulated in female liver (5.41 ± 0.66 mg.g-1 WM). It was noted that among all the samples studied for saturated (SFA) and monounsaturated fatty acids (MUFA) in male and female samples, palmitic acid C16:0 (18.00 ± 0.57 - 26.48 ± 0.99%TFA) and oleic acid C18:1 (11.79 ± 0.98 - 22.55 ± 0.37%TFA) were the predominant saturated and monounsaturated fatty acids respectively. All differences between male and female are statistically significant (p < 0.05) except these between the oleic acid (C18:1) values in gonads. Other more, docosahexaenoic acid (DHA) C22:6 (4.24 ± 0.72 -27.38 ± 2.97%) and eicosapentaenoic acid (EPA) C20:5 (4.55 ± 0.88 - 5.73 ± 0.68%) are the major PUFA. All differences between DHA values in male and female are statistically significant (p < 0.05). However, the EPA reveals a significant difference only between values obtained in male and female gonads. Our results suggest higher ω3 PUFA/ω6 PUFA and DHA/EPA ratios in male liver.
