摘 要:
以鱼粉和酪蛋白为蛋白源，添加鱼油、豆油、α-淀粉、纤维素以及适量的维生素和矿物质配制成试验饲料，蛋白质设置3个水平：41％、47％、53％，能量设置3个水平：1256．1、1465．5、1674．8kJ／100g。经过59d饲养点带石斑鱼幼鱼，以生长速度、净增重、增重率、蛋白质效率、饲料系数为评价指标，结果表明：点带石斑鱼幼鱼配合饲料中适宜的蛋白水平为47％，适宜的能量蛋白比为31．30～33．50kJ／g蛋白。[著者文摘]

Abstract:
The optimum ratio of dietary energy to protein for the grouper（ and determined using practical diets in a 3 × 3 factorial experiments. Epinephlus coioides ） fingerlings was Three energy levels of 1 256. 1, 1 465.5, 1 674.8 kJ/100 g at each protein level and three protein levels of 41%, 47% and 53% were utilized. The experimental fish [ initial body weight, （ 24.68 ± 1.20 ） g ] were reared in floating net cages （ 150 cm × 100 cm × 100 cm） for 59 days. Based on calculating weight gain, feed conversion rate and protein efficiency rate, the experimental results indicated that, for the grouper fingerlings, the optimum protein level was 47%, and the optimum ratio of dietary energy to protein was 31.30 -33.50 kJ/g.[著者文摘]
Key words:
