Challenge with fumonisin FB1 + FB2 alters profile of fatty acids in Nile tilapia fingerlings

The toxicity of fumonisin (FB) has been proposed for different fish species because it causes imbalance between the sphingoid bases and impairs several cellular processes, such as cell differentiation and growth. In this study, we tested the hypothesis that FB changes performance and modifies the fatty acid profile in the muscle of Nile tilapia fingerlings. A total of 180 fish were distributed in four treatments: control treatment (without addition of FB), 20 (FB20), 40 (FB40) and 60 (FB60) mg/kg FB) in order to measure performance, muscle yield, mineral residue, protein, total lipids and fatty acid content. The apparent daily gain was lower (Y = 0.019x2-0.124x + 0.325; R2 = 0.928) for fish fed diets containing FB compared to the control group. The negative effect on growth rates resulted in a reduction in fillet yield (P
