Fatty acid profile and assessment of heavy metals content of Sardina pilchardus captured in the Algerian coast

Total lipids, fatty acid composition and heavy metal content of Sardina pilchardus fillet samples captured in February ۲۰۱۴ in Beni saf, Mostaganem, Ghazaouet, Algiers and Jijet coast were evaluated. Total lipid content was related to the five sites of catch (p<۰.۰۵), ranging from ۷.۱۸ g ۱۰۰g-۱ for Algiers to ۱۰.۰۷g ۱۰۰g-۱ for Beni saf. The fatty acid composition of S. pilchardus shows a high content of polyunsaturated fatty acids (PUFAs) dominated by n-۳ fatty acids eicosapentaenoic acid (EPA C۲۰:۵ n-۳) and docosahexaenoic acid (DHA C۲۲:۶n-۳) with maximum rates of ۱۵.۷۵% and ۳۳.۴۲%, respectively (p<۰.۰۵). The saturated fatty acid (SFA) content was important in different samples of sardines, ranging from ۳۵.۵۰% to ۴۱.۳۲% according to sites of capture (p< ۰.۰۵). Concerning the heavy metals, the levels of lead (Pb) ranged from ۰.۰۱۳mg to ۰.۰۲۴mg, however those of mercury (Hg) varied from ۰.۰۸۰ mg to ۰.۱۳۰ mg (p<۰.۰۵), which affects the health value of the fish species
