为测定牙鱼平幼鱼饲料中的适宜蛋白质需要量进行了 8周投饵试验。使用鱼平均体重 (4 .1±0 .0 2 )g ,分别投喂含粗白质 35、4 5、5 0、5 5、6 5 %的饲料 ,日投饵率为鱼体重的 4 %～ 5 %。试验结束测出投喂含蛋白质 5 5 %饲料的鱼增重和饲料效率显著高于投喂含蛋白质 35 %和 4 5 Eight-week feeding trials were conducted to determine the appropriate protein requirements for flatfish juveniles. The average body weight of fish (4. 1 ± 0. 02) g, respectively, were fed 35,4 5,5 0,5 5,6 5% feed containing coarse white matter, feeding rate of 4% 5%. At the end of the experiment, the gain and feed efficiency of fish fed with 55% of dietary protein were significantly higher than that of 35% and 45%
