WANG Ji-qiao 1, XU Kun 2 (1.Key Laboratory of Maricultural Ecology, Ministry of Agriculture, PRC Dalian Fisheries Univ., Dalian 116023, China;2.Ocean and Fisheries Bureau, Yingkou 115000,China )  
New information on dietary nutrient requirements of various species of penaeid shrimp was reviewed briefly. Optimal dietary protein requirement of shrimp ranges from 300 g/kg to 570 g/kg, of which those of Penaeus setiferus, P. vannamei and P. stylirostris(280-350 g/kg)are lower than those of P. monodon(360-500 g/kg)and P. japonicus(450-570 g/kg). Carbohydrates are poorly utilized by shrimp and utilization rate of sugars increases with increase in structural complexity of the sugar they feed. Polysaccharides such as peptidoglycan and β-1,3 glucan(2.0 g/kg)can increase immunity when they are added into shrimp dietary. It recommended that optimal dietary lipid be 60-75 g/kg, not more than 100 g/kg, and that dietary highly unsaturated fatty acid requirement vary between 5 g/kg and 10 g/kg. Dietary vitamin and mineral requirements are summarized and a role of immunopotentiator in shrimp nutrition is discussed.
