Manipulation of fatty acid composition of Nile tilapia (Oreochromis niloticus) fillets with flaxseed oil

Nile tilapia ( Oreochromis niloticus ) is one of the most consumed species among freshwater fish reared in Brazil. However, studies show low levels of n‐3 fatty acids in freshwater fish reared in captivity in comparison with those reared in their natural habitats. The Nile tilapia used in this study were raised in captivity for a period of 5 months and fed varying amounts (0, 1.25, 2.5, 3.75 and 5%) of flaxseed oil as a substitute for sunflower...
