Effect of Isocaloric Diets with Varying Protein Level on Growth and Survival of Post-larvae of Macrobrachiutn rosenbergii

Abstract

Post-larvae of Macrobrachium rosenbergii (de man) were fed on an isocaloric diet (3100 K.cal DE/Kg) having different levels of protein (27.56, 34.12 and 41.12%) with protein: energy ratio of 88.16, 109.18 and 130.58 mg CP/K. cal respectively. The animals were reared for a period of six weeks under a temperature regime of 13-220C. The highest weight gain, specific growth rate and the best feed conversion ratio recorded were 165.61 mg, 3.35 and 1.69 respectively. The survival rates in ranged between 77.8 and 84%.
