The purpose of the study was to examine the fatty acid profiles of Nile tilapia (Oreochromis niloticus) submitted to different feeding times (0, 10, 20 and 30 days) on a diet enriched with n-3 fatty acids, by addition of flaxseed oil in substitution for sunflower oil. The main fatty acids detected were palmitic (C16:0), stearic (q18:0), oleic (C18:1n9), linoleic (C18:2n6) and alpha-linolenic (C18:30) in all the treatments. The 30 day-fed fish presented the best values for total n-3 fatty acids, with a prominence of alpha-linolenic acids, showing that the flaxseed oil as well as the feed supply time influenced the fatty acid profiles.
