Effects of Different Levels of Protein, Energy and their Interaction on Growth Factors of Indian white Shrimp iFenneropenueus indicusi of Different Sizes

Three experiments of 28 days duration were conducted in three sizegroups « ig. 1-5g and 5-1og) of indian white shrimp, fenneropenaeus indicus. toevaluate the appropriate protein: energy (ge) ratios in their diets. a commoningredient 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 of35%. 40~'i, and 45% and ge levels of 380, 420 and 460 kcal/loog at each level ofprotein (i.e:35:380, 35:420, 35:460: 40:380. 40:420, 40:460 and 45:380. 45:420and 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 tobe best in samples of
