    Effect of Season on Fatty Acid Composition and n-3/n-6 Ratios of Zander and Carp Muscle Lipids in Altinapa Dam Lake
    (WILEY-BLACKWELL, 2011) Güler, Gökalp Özmen; Aktümsek, Abdurrahman; Çakmak, Y. S.; Zengin, Gökhan; Çitil, O. B.
    In this study, seasonal variations on total fatty acid composition of carp, Cyprinus carpio, and zander, Sander lucioperca, muscle lipids in Altinapa Dam Lake were determined. Fish samples in 2 seasons (summer and winter) were obtained from Altinapa Dam Lake in Konya, Turkey. Polyunsaturated fatty acids were found to be higher during the cold season than in the hot both in zander and carp. Whereas the Docosahexaenoic acid was high in zander both in summer and winter, in carp it was high only during wintertime. Zander contained more n-3 fatty acids during the cold season compared to carp. Especially, the n-3:n-6 ratios in zander were 3.89 and 3.84 in summer and winter, respectively. In conclusion, seasonal variations affected fatty acid composition of zander and carp in Altinapa Dam Lake. Practical Application Fish oil is very important for human health because it contains long chain polyunsaturated fatty acids (PUFAs), especially n-3 PUFAs. No reports have been published about the effects of seasonal variations on the fatty acid composition of important species of carp and zander in Altinapa Dam Lake. In view of these facts, it is believed that carrying out a systematic work on lipid profile of carp and zander in this dam lake is necessary. Therefore, the aim of this work is to characterize and compare carp and zander muscle lipids in terms of their fatty acid in different seasons of the year. As a result, fatty acid compositions of 2 fish species muscle lipids have been identified. This is important for the consumers' health.
