The comparison of total fat and fatty acid profiles with some bio-ecological features of Capoeta capoeta umbla HECKEL, 1843 living in Tuzla Stream and Tercan Dam Lake

This study was carried out in 630 individual of Capoeta capoeta umbla populations caught from Tercan Dam Lake and Tuzla Stream between February 2006 and January 2007. It was determined that there were similarities with respect to length distributions (9.6 - 34.5; 9.5 - 35.3), b value from length - weight relationships (2.45 - 2.67), condition factors (1.18 +/- 0.01 - 1.17 +/- 0.01), Von Bertalanffy constants L(infinity), K, t(o) (52.15 - 0.137 - (-)1.351; 41.11 - 0.20 - (-)0.54) of lake and stream populations respectively, the differencs were also not significant in all compared properties. The most affected bio-ecological trait was reproduction times. Total fat values were higher in females than in males, but seasonally it was vice versa (38%, - 27%). Significant seasonal differences were determined with respect to total SFA (saturated fatty acids), MUFA (monoenoic unsaturated fatty acids, n-3, n-6 PUFA (polyunsaturated fatty acids) (p < 0.05).
