Abstract

In this study the fatty acid profile in tilápia Oreochromis niloticus alevins carcass, fed with enriched diets from flaxseed oil, was examined at different temperatures (23, 26, 29 and 32oC). Tilapia in its initial phase of development did not present differences (P >0.05) on physical-chemical and lipids compositions, at the different temperatures studied. The fatty acids profile, analyzed by gas chromatography using a capillary column, showed approximately 15% of n-3 fatty acids, with values around 0.12 to 0.18% for the eicosapentaenoic acid (EPA), and from 1.21 to 2.10% for the docosahexaenoic acid (DHA). Results showed that at lower temperatures 23 and 26oC, Nile tilapia grows less than at higher temperatures around 29 and 32oC. Temperature variation from 23 to 32oC did not influence on fatty acids profile of the alevins
