The Effects Of Dietary Fish Oil Replacement On Growth, Tissue Fatty Acid Composition And Fatty Acid Metabolism Of Red Hybrid Tilapia And Genetically Improved Farmed Nile Tilapia

Three related experiments were carried out to investigate the effects of dietary fish oil replacement in the feeds of farmed tilapia. The first feeding trial was conducted to investigate the effects of four different individual vegetable oils (VOs) with varying fatty acid profile as FO alternatives...
