Three experiments of 28 days duration were conducted in three size groups « Ig. 1-5g and 5-1Og) of Indian white shrimp, Fenneropenaeus indicus. to evaluate the appropriate protein: energy (GE) ratios in their diets. A common ingredient mixture consisting of fish meal, shrimp meal. ground nut oil cake, cholesterol. lecithin. vitamins and minerals blended with chicken egg albumin. tapioca tlour and cellulose (filler) to formulate nine feeds with protein levels of 35%. 40~יi, and 45% and GE levels of 380, 420 and 460 kcal/lOOg at each level of protein (i.e:35:380, 35:420, 35:460: 40:380. 40:420, 40:460 and 45:380. 45:420 and 45:460). Nutritional responses in terms of weight gain (g/individual), RGR, FCR, FCE, PER and PPV indicated that the protein: GE combination of 45:460 to be best in samples of
