The effect of dietary vitamin E and dietary lipids on growth and immune parameters of juvenile turbot (Scophthalmus maximus) were investigated in a series of experiments. The aims of the studies were to maximise immune function through dietary modulation to counteract stress induced immunodepression resulting from high stocking densities. In the first experimental trial, the vitamin E requirement for an optimum immune response was studied and revealed that vitamin E depletion induced poor health status, lower growth with some mortalities occurring at the end of the trial. However, supplementation of the diets with high levels of α-tocopherol although ensuring better growth did not significantly enhance most of the parameters measured at the end of the trial. The second trial aimed to test regimes coupling fresh or oxidised oil and low or high vitamin E supplementation. The results showed that vitamin E had a role in preventing peroxidation as high vitamin E supplementation improved some of the immunological ...
