本试验评估了(鱼回)(Ictalurus punctatus)主产区4种商品(鱼回)颗粒饲料(分别记为S_1、S_2、S_3和S_4,其中S_4为膨化饲料,其他均为颗粒饲料)和自行设计的颗粒饲料(记为S_5)对(鱼回)试验阶段生长性能、体色变异、肝胰脏组织结构及 (鱼回) 形态指标的影响.7周的饲喂试验结果显示:饲料蛋白含量为38%的S_4膨化饲料可明显的提高养殖鱼的体重,平均增重率为262.6%,但存活率较低,仅为72.3%;而喂养S5饲料组(鱼回)的增重率为168.89%,且存活率为92.4%,高于其他饲料组.养殖结束后,不同试验组(鱼回)的肥满度、脏体比有所差异,但均未达到显著性水平(P>0.05).投喂S_2饲料组养殖鱼体体色发白比较明显,体色异常比...

This experiment was conducted to evaluate effects of four kinds of commercial channel catfish feeds （ named as S1 -S4, S4 was extruded feed, and others were pellet feeds） from Changyang area and one kind of feed formulated by ourselves （ S5 ） on growth performance, body color variation and histological structure of hepatopancreas and morphology of channel catfish. 7-week feeding trial showed： S4 containing 38% protein can significantly improve juvenile＇s weight, the average growth rate was 262. 6% , but the survival rate was only 72. 3% ;...
