Variations in the fatty acid compositions of the liver and gonad tissue of spiny eel (Mastacembelus mastacembelus) from Atatürk Dam Lake.

Methods: Total lipids were extracted with 5 mL of chloroform-methanol (2:1 v/v). Samples containing gonad and liver lipid were transesterified with acidified methanol. The fatty acid methyl esters were extracted with hexane. Fatty acids were detected by gas chromatography (GC). Results: The major saturated fatty acids (SFAs) were myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) in both gonad and liver tissue. Oleic acid (C18:1 ω-9) and palmitoleic acid (C16:1 ω-7) were the prominent monounsaturated fatty acid (MUFA). The dominant polyunsaturated fatty acids (PUFAs) were linoleic acid (LA, C18:2 ω-6), arachidonic acid (AA, C20:4 ω-6), docosapentaenoic acid (C22:5 ω-3) and docoesahexaenoic acid (DHA, C22:6 ω-3). The ratio of ω-3/ω-6 ranged from 1.55 to 3.44 and 1.18 to 2.71 in the gonad and liver tissue, respectively. Conclusion: The findings of this study will be useful for understanding the seasonal distribution of fatty acid composition in the liver and gonad of spiny eel.eninfo:eu-repo/semantics/openAccessFatty acidFreshwater fishGonadLiverMastacembelus mastacembelusArticle426617623WOS:0004239895000052-s2.0-8503759241710.1515/tjb-2017-0045Q3Q4
