摘　　要：设计3种不同配方的黄颡鱼配合饲料,选用2m×2m×1.2m小网箱进行饲养对比试验,饲养150d,试验结果表明,投喂配方Ⅰ、Ⅱ、Ⅲ的黄颡鱼体重分别平均增重90.4、66.3和76.3kg;饲料系数分别为1.63、2.19和1.98;成活率分别为97.0%、95.7%和96.3%。经数理统计分析得出养殖效果:配方Ⅰ>配方Ⅲ>配方Ⅱ。Pelteobagrus fulvidraco was reared with three kinds of mixed feed in netty box (2m×2m×1.2m) for 150 days, the rearing effects of different mixed feed were compared. The results indicated that through rearing with mixed feed Ⅰ,Ⅱ and Ⅲ, the average weight gain of tested fishes was 90.4, 66.3 and 76.3kg respectively, their survival rate was 97.0%, 95.7% and 96.3% respectively, the feed coefficient was 1.63, 2.19 and 1.98 respectively. The mathematical statistical analysis showed that three kinds of mixed feed could be sorted by their rearing effects as follows: mixed feed Ⅰ> mixed feed Ⅲ> mixed feed Ⅱ.
