Effect of Dietary Inositol on Growth, Feed Utilization and Blood Biochemical Parameters for Juvenile Barramundi (Lates calcarifer Bloch)

Problem statement: The utilization of inositol was detected for growth performance and erum biochemical parameters of juvenile barramundi (Lates calcarifer). Approach: A 56 day feeding trial was conducted to evaluate the effect of inositol on growth, feed utilization and serum biochemical parameters for juvenile barramundi Lates calcarifer (initial size 5.51±0.07g). Six experimental fish meal-based isonitrogenous (42% crude protein) and isolipidic (10% crude lipid) diets containing levels of inositol (350, 364, 458, 507, 720, 1050 mg kg-1 diet) were formulated. Results: Fish fed diet containing inositol 507 mg kg-1 diet had the significantly highest weight gain (WG, %) among all the groups (p 0.05). However, significantly lower Viscerasomatic Index (VSI) was found in fish fed diet without supplemental inositol (p 0.05). Total protein and triacylglycerol in serum increased with increasing dietary inositol levels up to 507 mg kg-1 diet (p
