摘 要：
为了考察有氧运动训练对中华倒刺鲃幼鱼形态特征的影响,在(25±0.5)℃水温条件下,将大小相当的144尾中华倒刺鲃幼鱼(19.52±0.03)g,(10.29±0.02)cm轻度麻醉后随机分为4组:对照组、1bl/s(体长/秒)训练组、2bl/s训练组和4bl/s训练组,在相应流速下训练8周(18h/d)后,从各实验组中各随机挑选中华倒刺鲃,幼鱼12尾,测量并计算其形态特征参数.结果显示1bl/s训练组尾柄侧面积显著大于对照组(p<0.05);2bl/s训练组的腹鳍前长、头长、叉长、尾柄侧面积及尾鳍面积等参数均显著大于对照组(p<0.05);而4bl/s训练组头高、体高、体高与体长比显著大于对照组(p<0.05),其他形态参数较对照组无显著差异.研究结果表明有氧运动训练对中华倒刺鲃幼鱼的形态特征产生了显著影响;中华倒刺鲃幼鱼在不同流速下表现出的形态特征差异可能与其游泳速度和能量消耗相关.

摘 要：
To investigate the effects of aerobic exercise training on the morphological characteristics of juvenile Spinibarbus sinensis,144 fish(19.52±0.03 g,10.29±0.02 cm) were subjected to aerobic training for 8 weeks at a water velocity of control(3 cm/s),1,2 and 4 body length/s(bl/s) at a constant temperature of 25±0.5 ℃.The morphological images and related parameters were measured at the end of the training period.The side area of caudal peduncle in the 1 bl/s training group was significantly greater than that in the control group(p<0.05).The prepelvic length,head length,fork length,area of caudal fin and side area of caudal peduncle in 2 bl/s training group were significantly higher than that in the control group(p<0.05).The head depth,body depth and the ratio of body depth and body length were significantly greater in 4 bl/s training group compared with the control group(p<0.05).Aerobic exercise training showed no effect on the other morphological parameters when compared to the control group.These results suggested that(1) the morphlogical characteristics of S.sinensis were impacted by the aerobic erercise training;(2) the difference of the morphological characteristics at different water velocities may be related to swimming speed and energy efficiency in juvenile S.sinensis.
