Effects of dietary wheat middlings and supplemental phosphorus on growth of turbot, Scophthalmus maximus Linnaeus, 1758

This study was carried out to determine the effects of replacement wheat flour with middling (WM) and supplemental phosphorus at a level 1% on growth nutrient utilization, whole body, fillet, viscera liver proximate compositions in turbot, (Scophthalmus maximus Linnaeus, 1758). The control diet based mixture three fish meals flour. Fish an average initial weight 266.67±0.72 g were fed experimental diets for 9 weeks. Each treatment tried four replicates. At end experiment, there no significant rate, utilization parameters such as feed intake, conversion ratio, protein efficiency nitrogen, lipid energy gains retentions, hepato-somatic index, viscero-somatic condition factor, body (except dry matter which significantly lower P added than control) organ compositions. findings suggest that WM can totally replace is tendency positive contribution dietary supplementation response variables.
