Özet

The aim of the study was to evaluate the seasonal variations in both fatty acids composition and omega 6/omega 3 ratio of polyunsaturated fatty acids in muscle of pike (Esox lucius) living in Karamik Lake, Turkey. The total amounts of saturated, monounsaturated and polyunsaturated fatty acids were found to be 26.82, 20.16 and 44.54 % in spring; 30.78, 21.93 and 42.57 % in summer; 25.67, 20.76 and 47.11 % in autumn; and 26.66, 17.13 and 51.51 % in winter, respectively. In winter, omega 9 fatty acids amount was the lower than that of omega 3 and omega 6 fatty acids..The omega 6/omega 3 fatty acids, arachidonic acid to eicosapentaenoic acids, ratios were 0.30 and 0.98 in spring, 0.38 and 0.97 in summer, 0.44 and 1.11 in autumn, and 0.43 and 1.34 in winter, respectively. The results obtained showed that the amount of polyunsaturated fatty acids in muscle tissue of pike is very high in all seasons, and this fish might be an important source of omega 3 fatty acids for mankind.
