摘　　要：为考查运动锻炼对鲤鱼(Cyprinus carpio)幼鱼形态特征的影响,在25℃条件下将60尾体长为(7.1±0.39)cm的实验鱼,以60%临界游泳速度(Ucrit)持续运动锻炼15 d,每天锻炼时间分别为6 h和12 h,对照组锻炼时间为每天0 h;随后分别进行有关形态特征图像及相关参数的测定。结果显示,6 h和12 h实验组的叉长(FL)、尾柄侧面积(S)的值与对照组相比均显著增大(p<0.05);而头高(HD)、体高(BD)和体高比体长(H/L)的值都显著减小(p<0.05);6 h和12 h实验组之间比较,12 h处理组的BD值和H/L值比6 h处理组的显著变小(p<0.05);其中,与对照组相比6 h和12 h组S值增加的比率为5.8%和9.5%,而H/L值分别降低3.4%和6.9%。研究认为,运动锻炼对实验鱼的形态特征及相关参数均产生影响,且这种影响随锻炼强度的提高而增大;运动锻炼对鲤鱼幼鱼产生的这种影响可能会使它们的游泳运动速度及能量效率得到显著提高。To investigate the effects of exercise training on the morphological parameter of juvenile common carp（Cyprinus carpio）,the morphological images and related parameters were measured in juvenile common carp（body length,（7.1±0.39） cm,n=60） after exercise training for 15 days.The exercise training water flow rate was 60% critical swimming speed（Ucrit） and the exercise training duration was 0 h（control）,6 h and 12 h daily and the water temperature was maintained at 25 ℃ conditions.The results revealed that the fork length（FL） and the caudal area（S＇） of 6h and 12 h exercise trained groups increased significantly（p0.05）,while head depth（HD）,body depth（BD） and the body depth： body length ratio（H/L） reduced significantly（p0.05）,respectively,compared with those of the control group.Between the two experimental treatment groups,the values of BD and H/L of 12 h exercise trained group were significantly smaller than those of 6 h exercise trained group（p0.05）.Compared with the control group,the caudal area of 6 h and 12 h exercise trained groups increased 5.8% and 9.5%（p0.05）,and that the H/L decreased 3.4% and 6.9%（p0.05）.The results suggested that the morphological characteristics and related parameters were impacted by the exercise training and training effects was strengthened with the intensity of exercise.The juvenile common carp may increase the swimming speed and the energy efficiency during swimming after exercise training.
