The aim of the present study is to determine the content of fatty acids (FA), fat-soluble vitamins (A, D, E and K) and cholesterol in the muscle tissue of shabut (Arabibarbus grypus, Heckel 1843) from Keban Dam Lake. For this purpose, 40 specimens were obtained between December and March (2013). Muscle samples (without skin) taken from each fish were homogenized. Fat-soluble vitamins (A, D, E and K) and cholesterol were analysed simultaneously using HPLC (High-performance liquid chromatography) system. The fatty acids, grouped as saturated fatty acid (SFA), mono unsaturated fatty acid (MUFA) and polyenoic fatty acids (PUFA), were analysed by gas chromatography as the methyl esters. The results of present study showed that MUFA was the highest followed by SFA and PUFA. The highest fatty acid levels found in Shabut throughout all months (December– March) were 16:0, 18:1, 22:6 n-3 (DHA) and 20:5 n-3 (EPA). Shabut had low cholesterol level. Among the fat-soluble vitamins (A, D, E and K) analysed in all months, the vitamin E content was highest followed by K, D and A. In conclusion, it can be stated that Shabut (A. grypus) has comparatively good fatty acid composition, fatsoluble vitamins content and low cholesterol level. Shabut (A. grypus) can therefore be recommended for human consumption as a comparatively good source of nutrition.
