Palmitik asit doymuş yağ asitidir ve diğer dominant yağ asidi her iki türde de stearik asitdir. Kızılkanattaki doymuş yağ asidi içeriği bütün mevsimlerde %26.79 ile % 41.54 arasındadır. Oleik asit C18:1 ?9 her iki balık türünde, bütün mevsimlerde primer doymamış yağ asidi olarak bulunmuştur. Kefalde, oleik asit C18:1(%15.09-%28.56) kızılkanata nazaran bütün mevsimlerde yüksek miktara sahiptir. Kızılkanat kas lipitlerinde dokosahexaenoik asit (DHA) (22:6?3) dominant aşırı doymamış yağ asidi olarak tespit edilmiştir. Bu verilere göre her iki tatlı su balığının DHA ve eikosapentaenoik asit (EPA) yönünden iyi bir kaynak olduğu sonucuna varılmıştırFatty acid compositions of the muscle lipids and its seasonal variations in Scardinius erythrophthalmus (rudd) and Squalius cephalus (chub) in Sapanca and Terkos Lake, were examined using a gas chromatographic method. Palmitic acid is saturated fatty acid and the other dominant fatty acid is stearic acid in both species. SFA contents in rudd were between 26.79% and 41.54% in all seasons. Oleic acid C18:1 ?9 was identified as the main monounsaturated fatty acid (MUFA) in both fishes for four seasons. It was found that chub had a high amount of C18:1 (15.09% to 28.56 %) in all seasons compared to rudd. It was noticed from the present data that docosahexaenoic acid (DHA) (22:6?3) was predominant PUFA in muscle lipids of rudd. According to these data, it can be concluded that both freshwater fishes are a good sources for eicosapentaenoic acid (EPA) and DHAeninfo:eu-repo/semantics/openAccessmuscle,fatty acidseasonal changeskas dokusuyağ asidimevsimsel değişiklikArticle101104109
