Abstract :
Abstract The effects of dietary inulin on the growth performance and some hemolymph parameters of the Pacific white shrimp (Litopenaeus vannamei) were investigated for a 5-week feeding trial. The experiment, carried out in triplicate, was conducted in circular PVC tanks of 300 L capacity, filled with 200 L of seawater. Each tank was randomly stoked with 25 individuals of 3.20±0.02 g average weight. The shrimp was fed three times a day at 08:00, 14:00 and 20:00, in satiation form with dietary inulin level of 2%, and a blank feed (without inulin) as control. There were no significant differences in weight increase percentage (BWI), specific growth rate (SGR), orbital carapace length gain, protein efficiency ratio (PER), food conversion ratio (FCR), survival and muscle chemical composition (moister, protein, fat and ash) as compared with control group but daily feed intake was significantly higher in treatment. Hemolymph parameters were higher compared to the control group but it was not
