In this study, the fatty acid profile in Squalius semae muscle tissue captured from Kuzgun Dam was determined using gas chromatography. As a result of the study, a total of 26 fatty acids were identified, including 9 saturated fatty acids (SFA), 10 monounsaturated fatty acids (MUFA) and 7 polyunsaturated fatty acids (PUFA). Our results showed that polyunsaturated fatty acids (PUFA) (46.49%) were found in higher proportion than saturated fatty acids (SFA) in muscle tissue, followed by MUFAs (28.01%) and SFAs (25.5%). Palmitic acid (C16:0) (16.19%) is the main saturated fatty acid, while docosahexaenoic acid (DHA, C22:6 n−3) (13.75%) and eicosapentaenoic acid (EPA, C20:5 n−3) (12.18%) was determined as the main polyunsaturated fatty acid. In conclusion, S. semae is nutritionally valuable for human consumption and can be consumed by the consumer as an alternative food source.

Bu çalışmada, Kuzgun Barajından yakalanan Squalius semae kas dokusundaki yağ asidi profili, gaz kromatografisi kullanılarak belirlenmiştir. Çalışma sonucunda, 9 doymuş yağ asidi (SFA), 10 tekli doymamış yağ asidi (MUFA) ve 7 çoklu doymamış yağ asidini (PUFA) içeren toplam 26 yağ asidi tespit edilmiştir. Sonuçlarımız kas dokusundaki çoklu doymamış yağ asitlerinin (PUFA) (%46,49) doymuş yağ asitlerine (SFA) göre daha yüksek oranda bulunduğunu göstermiştir ve bunu MUFA'lar (%28,01) ve SFA'lar (%25,5) izlemiştir. Palmitik asit (C16:0) (%16,19) ana doymuş yağ asidiyken, dokosaheksaenoik asit (DHA, C22:6 n−3) (%13,75) ile eikosapentaenoik asit (EPA, C20:5 n−3) (%12,18) ana çoklu doymamış yağ asidi olarak belirlenmiştir. Sonuç olarak, S. semae besin açısından insan tüketimi için değerlidir ve tüketici tarafından alternatif besin kaynağı olarak tüketilebilir.
