Abstract
[目的]提高花鳗鲡的养殖效益.[方法]在工厂化循环水养殖系统条件下,探讨不同温度对花鳗鲡日增重、摄食率及特定生长率的影响.[结果]规格为(197.62±7.98) g/ind的花鳗鲡摄食和生长的适宜温度范围为28.5~29.5℃,在适温范围内的最大日增重为1.831 g/d,最大摄食率为0.738%/d,最大特定生长率为0.831.规格为(451.49±12.78) g/ind的花鳗鲡摄食和生长的适宜温度范围为28.5 ~29.5℃,在适温度范围内的最大日增重为2.860 g/d,最大摄食率为0.659%/d,最大特定生长率为0.588.[结论]花鳗鲡生长适宜的温度为28.5 ~29.5℃.
