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

摘要

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 13-22 deg C. 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%.
