用膨化饲料、鲜活饲料和以上两种饲料的配量物,分别设计三个梯度蛋白质的投饲水平,对鲈鱼幼鱼进行对比饲养。结果表明,用膨化饲料每天提供每百克鱼1.20g蛋白质,有最好的生长率、消化率、投饲料系数和较好的成活率、较低的饲料散失率。从而认定用膨化饲料投喂有较好的养殖效果和保护养殖水环境的效益。 With the puffed feed, fresh feed and the above two kinds of feed ingredients, respectively, the design of the three gradient protein feeding levels, the bass juvenile feeding comparison. The results showed that, with puffed feed per day to provide 1.20g protein per 100 grams of fish, have the best growth rate, digestibility, feed conversion coefficient and better survival rate, lower feed rate of loss. So that puffed feed fed with better breeding effect and the benefits of aquaculture water environment protection.
