The average food consumption of formulated feed rich in carbohydrates (Feed 2) showed minimum consumption (0.479 g dry weight), faecal production (0.061 g dry weight) and Food Conversion Ratio (0.471) as compared to protein rich Feed-1 where these values were maximum. The assimilation efficiency (86.78%) and average gross efficiency (198.47%) was higher in Feed-2 as compared to these values obtained for other feeds. Mean relative growth (14.29%) and asymptotic weight (300 g) was calculated maximum for Feed -2 whereas, it was minimum for Feed-1. The von Bertalanffy’s growth equation fitted well to describe the growth pattern of the juveniles and represented as: Wt=180[1-e^{-0016(t+3.75)}] for Feed-1; Wt=300[1-e^{-0.0013(t+3.00)}] for Feed-2; Wt=220[1-e^{-0.0015(t+3.33)}] for Feed-3; Wt=240[1-e^{- 0.0016(t+3.18)-0.0015(t+3.60)}] for Feed-5 Keywords : Food conversion ratio; assimilation efficiency; shrimp feed
