Abstract

The effect of different dietary lipid to carbohydrate ratios on the growth and food conversion of postlarvae of freshwater prawn Macrobrachium rosenbergii was studied. The experiment was conducted for 45 days with postlarvae ranging from 0.018 to 0.019 g. Six diets with different lipid to carbohydrate ratios of 1:20.5; 1:10.4; 1:6.8; 1:4.6; 1:3.7 and 1:2.8 with constant 30% protein were formulated. The diet with lipid to carbohydrate ratio of 1:3.7 (10% lipid and 37.05% carbohydrate) exhibited better performance among the test diets in terms of weight gain, specific growth rate (SGR), protein efficiency ratio (PER), food conversion ratio (FCR) and survival.
