| 摘 要： | 在室内控温水族箱中设6℃、11℃、16℃和21℃四个水温组,饲养7周,研究了初始体重为1.72±0.24g的细鳞鱼（Brachymystax lenok）幼鱼摄食和生长的最适水温。结果表明,16℃时细鳞鱼的特定生长率（SGR）、日增重（DWG）、食物转化率（FCE）和摄食率（FI）显著高于其他处理组。这些参数与水温（T...

| Abstract: | The optimum temperature for growth and feeding was studied in lenok Brachymystax lenok weighing 1.72±0.24g at of 6℃,11℃,16℃,and 21℃for 7 days in a laboratory.The results showed that the specific growth rate（SGR）,daily weight gain（DWG）,food conversion efficiency（FCE）and feed intake（FI） were found significantly higher than those in other groups at 16℃.The correlations between these parameters and water temperature（T） were described by nonlinear regression models： SGR=（-2.601）＋（0.887）T＋（-0.027）T2（P0.01,R= 0.979）,FI=（0.111）＋（0.292）T＋（-0.009）T2（P0.01,R=0.990）,FCE=（52.828） ＋（11.951） T＋（-0.393） T2（P0.01,R=0.933）.It is concluded that the optimum temperature was showed to vary from 15.20℃ to 16.43℃. |
