摘　　要：采用群体实验方法,探讨了摄食水平和温度对漠斑牙鲆(Paralichthys lethostigma)幼鱼生长率的影响。结果显示:漠斑牙鲆幼鱼特定生长率(SGRW)与摄食水平呈一定的正相关关系;在1%摄食水平下,温度与SGRW呈极显著的正线性相关关系(P<0.01),而饥饿与4%摄食水平下,温度与SGRW无显著相关性(P>0.05)。Effects of levels and temperature on the growth rate of the young of Paralichthys lethostigma were studied by population experiment. The results showed that： the relation between the specific growth rate （SGRw ）and ration levels of the young of P. lethostigma can be described as straight line. The temperature had irregular impact on SGRw at different ration level. The linearity relation of between SGRw and temperature indicates that the temperature significantly affects SGRwwhen dietary level is 1% （P 〈0.01 ）. However, the temperature does not remarkably affect SGRw with on the occasion of hungriness and 4% of ration level（P 〉0.05） ）.
