Abstract :In this study, fatty acid profiles of rainbow trout, which has been bred in farms, and the trouts escaping from the farm to the nature insert ignore into journalissuearticles values(fish living in the canal between the farm and the Körkün Brook); and, which escaped from the farm and reached the Körkün Brook and fed here with natural nutrients have been compared. The rainbow trout obtained from the culture medium and the trout escaping from the farms to the nature were found to be significantly different in the fatty acid profile. The basic fatty acids of the samples taken from our research groups are; myristic acid insert ignore into journalissuearticles values(C14: O-);, palmitic acid insert ignore into journalissuearticles values(C16: 0);, palmitoleic acid insert ignore into journalissuearticles values(C16: 1);, heptadecenoic acid insert ignore into journalissuearticles values(C17: 1);, stearic acid insert ignore into journalissuearticles values(C18: 0);, oleic acid insert ignore into journalissuearticles values(C18: 1 n9);, linoleic acid insert ignore into journalissuearticles values(C18: 2 n6);, vaccenic acid insert ignore into journalissuearticles values(C18: 1 n7);, linolenic acid insert ignore into journalissuearticles values(C18: 3 n3);, arashidic acid insert ignore into journalissuearticles values(C20: 0);, arashidonic acid insert ignore into journalissuearticles values(C20: 4n6);, eicosapentaenoic acid insert ignore into journalissuearticles values(C20: 5 n3);, eruric acid insert ignore into journalissuearticles values(C22: 1 n9);, docosahexaenoic acid insert ignore into journalissuearticles values(C22: 6 n3);. In our study, saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were determined respectively; 29.389-21.451%, 25.36-59.49% and 34.17-18.56%. As a result, the habitats and feeding of the fish affected the fatty acid profile of rainbow trout.
