Investigation of fatty acid profiles in some economically important fish species living in Atatürk Dam Lake, Adıyaman, Türkiye

This study aims to deter-mine the fatty acid profile of 10 fish species (Carassius gibelio (Bloch, 1782), Chondrostoma regi-um (Heckel, 1843), Cyprinus carpio (Linnaeus, 1758), Carassius auratus (Linnae-us, 1758), Alburnus sellal (Heckel, 1843), Planiliza abu (Heckel, 1843), Capoeta trutta (Heckel, 1843), Arabibarbus grypus (Heck-el, 1843), Mastacembelus mastacembelus (Banks & Solander 1794) ) caught from Atatürk Dam Lake, sold by fishermen and con-sumed by local people. Ac-cordingly, the fish species identification was made and the individuals belonging to the determined species were randomly selected and mus-cle tissue was taken from each sample for fatty acid analysis and put into tubes. Extraction of fats from muscle tissue was carried out using a chloroform-methanol solvent mixture. The methylation process of fatty acids was carried out using the TS EN ISO 12966:2 method. Analyzes were performed with Ther-mo brand Trace GC model GC with FID (Flame Ion De-tector) detector. A 60 m HP-88 column was used in the analysis. It has been deter-mined that 10 fish species contain a total of 26 differ-ent fatty acids. Palmitic acid is the major fatty acid among saturated fatty acids (SFA). Palmitic acid values vary between 18.31 % and 25.51 %. It was determined the most in C. carpio and the lowest in C. auratus. Among the mono unsaturat-ed fatty acids (MUFA), ole-ic acid is the major fatty ac-id and was found between 12.70 % and 29.77 %. It was detected at most in A. sellal with a rate of 29.77 % and in P. abu with a minimum rate of 12.70 %. Of the pol-yunsaturated fatty acids (PUFA), docosahexaenoic acid is seen as the major fat-ty acid. It was detected at most in C. trutta with a rate of 14.24 %, and at a mini-mum in C. carpio with a rate of 0.62 %.
