摘要
采用食物平衡法,研究了体重和温度对福寿螺摄食水花生的影响,得到了福寿螺在不同体重和温度下的最大摄食率模型,为水花生的资源化利用和降低特种动物养殖饲料成本提供定量依据。随着体重的增加和温度的下降,福寿螺的最大摄食率和特定生长率降低,饵料系数增加(p<0.01)。
In the paper the effect of body and temperature of apple snail on its consuming alligator weed indoor was studied and the model of maximum ration levels（ RLmax ） under the different body weights and temperatures was gained, which would provide the quantitative basis for the resource utilization of alligator weed and the reduction of feed cost in special animals culture. RLmax, and special growth rate were decreased and the feeding coefficient was increased with its body weight-increasing and temperature-decreasing（p 〈 0.01 ）.
