Effects of Dietary Protein and Lipid Levels on Growth, Nutrient Utilization, and the Whole‐body Composition of Turbot, Scophthalmus maximus , Linnaeus 1758, at Different Growth Stages
Abstract Three 9‐wk feeding trials were performed to assess the effects of dietary protein and lipid levels on the growth, feed utilization, and body composition of turbot, Scophthalmus maximus Linnaeus, at three different growth stages with initial average weight 4.5 ± 0.01, 59.1 ± 0.24, and 209.1...
