将人工养殖的大鲵100尾,随机分为5组,每组20尾。饲养时间从1龄末至3龄末,共两年时间。在适宜的饲养环境下,第2年每尾大鲵平均从25～30g增重到223～351g,净增重198～321g,增重率达792%～1070%,生长态势非常迅速。第3年大鲵从223～351g增重到582～904g,净增重359～553g,增重率达158%～184%,生长态势比较迅速。 100 farmed mandarin fish were randomly divided into 5 groups of 20 each. Feeding time from the end of 1 to 3 end, a total of two years time. In the suitable feeding environment, the average weight of each big tailed apple in the second year increased from 25-30g to 223-351g, the net weight gain was 198-312g, the weight gain rate reached 792% -1070%, and the growth trend was very fast. In the third year, the weight of bulrush increased from 223g to 351g to 582g to 904g, the net weight gain was 359g to 553g, and the weight gain rate reached 158% to 184%.
