The effects of dietary Schizochytrium sp. supplementation on growth and survival rate of giant freshwater prawn (Macrobrachium rosenbergii) were studied. The prawns (approximate weight of 0.5 g/prawn) were fed with pelleted feed supplemented with Schizochytrium sp. at the levels of 0% (control group), 2.5%, 5.0%, 7.5% and 10.0%. Fifteen prawns were used for each treatment with the experiments being carried out in triplicate. Initial weight of the prawns was measured at the beginning of the experiment and after culturing for 50 days in suitable conditions, final weight, weight gain and survival rate of the prawns were recorded. The results showed that survival rates of the prawns were not significantly different regardless of levels of Schizochytrium sp.... |
