采用适量投喂法对稚鳖在 2 9 5℃、30℃、30 5℃、31℃、32℃等不同温度下的摄食及生长进行研究 ,发现在 30 7℃稚鳖个体增重最快 ,2 9 8℃饲料系数最低。在 30℃以内 ,稚鳖的生长速度随着水温的上升而加快 ,当水温超过 30℃时 ,稚鳖的生长速度却随着水温的上升而下降。在不同的温度下 ,稚鳖的生长速度差异显著。日投饲率为 2 8%～ 3 0 % ,全天投喂的饲料中 ,上午占 1/ 3 ,下午或晚占 2 / 3
The feeding and growth of juvenile soft-shelled turtle at different temperatures of 295 ℃, 30 ℃, 305 ℃, 31 ℃ and 32 ℃ were studied by using proper feeding method. The results showed that the weight gain of juvenile soft-shelled turtle at 30 ℃ was the fastest, 2 9 8 ℃ lowest feed coefficient. Within 30 ℃, the growth rate of juvenile turtle accelerated with the increase of water temperature. When the water temperature exceeded 30 ℃, the growth rate of juvenile turtle decreased with the increase of water temperature. At different temperatures, the growth rate of juvenile turtle is significantly different. Feeding rate of 28% ~ 30%, day-fed feed, the morning accounted for 1/3, afternoon or late accounted for 2/3
