This study evaluates the potential health effects of omega-3 fatty acid supplementation on tilapia physiology and immunology. Tilapia were fed diets supplemented with linseed oil (LO; high in omega-3s), sunflower oil (SO; low in omega-3s) or no extra oil (control) for 12 weeks. Blood glucose was significantly reduced in LO and SO over time and significantly lower than the control. Packed cell volume and spleen somatic index were significantly reduced in LO and SO over time but not different from the control. Plasma protein was significantly higher than the control for both LO and SO. Phagocytosis was increased only in LO and was significantly higher than SO. Higher dietary lipid levels confer some health benefits, and omega-3 supplementation enhances phagocytic activity.
