通过对6种不同供饵条件下网箱养草鱼试验结果的分析,探讨了不同供饵条件对草鱼营养生长特性的影响。结果表明:配方合理的草鱼用膨化饲料加适量青料投喂组网箱草鱼生长效果最明显,每尾是均增重高达12.2081;主蛋白饲料豆饼、棉饼、菜饼按1.00:1.25:3.75的比例进行配方较合理;试验网箱鱼肌肉、血液、肝脏的总糖、总脂、总蛋白质含量均高于同规格池塘草鱼的相应指标,肝脏总脂含量虽高但非“脂肪肝”。
The effects of different feeding conditions on the vegetative growth characteristics of grass carp were discussed by analyzing the results of six different feeding experiments. The results showed that the grass carp with the reasonable formula grass puffed feed plus proper amount of green material had the most obvious growth effect, with the weight gain of 12.2081 at each tail. The main protein feed soybean cake, cotton cake and vegetable cake were 1.00: 1.25: 3.75 The total sugar content, total fat content and total protein content in the muscle, blood and liver of the experimental cage fish were higher than the corresponding indicators of the grass carp in the same size. The total lipid content of the liver was higher than that of the non-fatty liver, ".
