Özet
The effects of seasonal variation on the fatty acid composition of total lipid, triacylglycerol, and phospholipid in the dorsal muscle of Capoeta trutta were assessed by gas chromatographic method. A total of 18 different fatty acids were determined in the composition of C. trutta. The variations in fatty acid composition of total lipid, triacylglycerol, and phospholipid were recorded throughout the seasons. The total polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (M UFA) were the most important groups of total lipid. Total saturated fatty acid (SFA) and total MUFA were seen to increase from spring to summer while total PUFA decreased sharply from spring to summer. These seasons corresponded to the beginning and end of the reproduction period, respectively. The major fatty acids of total lipid in all seasons were C16:0, C18:1n-9, C20:4n-6, C20:5n-3, and C22:6n-3. In the present study, n-3/n-6 ratios of total lipid were 3.20, 4.11, 1.69, and 1.45 in spring, summer, autumn, and winter, respectively. MUFA and PUPA were the most important groups of triacylglycerols. Of these, the main fatty acids were found to be C16:0, C16:1n-7, C18:1n-9, and C20:5n-3. PUFA were determined to be the most important group of phospholipids. The major fatty acids identified in the phospholipid group were C16:0, C18:1n-9, C20:5n-3, C22:5n-3, and C22:6n-3 in all seasons. In conclusion, it was shown that the fatty acid compositions in the muscle of C. trutta was significantly influenced by the seasons and that, in light of their n-3/n-6 ratios, C. trutta should be considered a desirable food in the human diet.
