The experiment was conducted in Aquaculture lab of CIFE (New campus) and fingerlings (5-6cm in size) of mrigal were brought from carp hatchery. Four compositions of experimental diet were prepared by using microfloc with fishmeal in different ratio and control without microfloc. For the preparation of biofloc Ammonium chloride (NH4Cl2) used as a nitrogen source (100g) and Sucrose (100g) as a carbohydrate source. Three treatments with each of triplicate were used to get the maximum accuracy in result. Fingerlings were fed with experimental diet with 5% of body weight (BW). Sampling was done at 10 days interval. At the end of the experiment, the various parameters of fingerlings were determined using best statistical methods. Apart from four treatments (T) the mean weight gain in control (0.87±0.20), T1(1.05±0.18), T2(1.30±0.21)and T3(1.62±0.09), maximum mean weight gain i.e. 1.62±0.09gm, was observed in case of fingerlings fed with 1:1 ratio of microfloc and fish meal respectively. Similar results were seen in case of Specific Growth Rate (SGR) where it was 0.31±0.02gm for T3. The overall experiment shows the fingerlings fed with microfloc gives better specific growth and mean weight gain.
