Abstract

The effect of dietary protein (40%, 45%, 50%, 55% and 60%) on growth, survival, feed conversion ratio(FCR), feed conversion efficiency(FCE), specific growth rate(SGR) and body weight gain (BWG) were investigated for juveniles of Fenneropenaeus merguiensis. The best growth was obtained with the diet containing 60% dietary protein. Feed conversion ratio decreased with increasing weight of prawn and is negatively correlated with dietary protein level. The FCR was found to be minimum (0.31) in 60% dietary protein and maximum (1.274) in 40% dietary protein. FCR and FCE were found to differ significantly between prawn fed 40-45% and 50-60% dietary protein. BWG differs significantly among each treatment but SGR differs between prawns fed 40-45% and 50-60% dietary protein. Percentage body protein of prawn fed 50-60% was higher than that of prawn fed 40-45% dietary protein, whereas lipid content decreased with increasing dietary protein level. Overall growth performance of Fenneropenaeus merguiensis was significantly higher (P>0.5) in the diet containing 60% dietary protein when compared with 40%, 45%, 50% and 55% dietary protein.
