| 摘 要： | 为查明运动过程中罗氏沼虾的行为特征及其与肌肉能量代谢的关系，实验设置了对照、低、中、高4种不同强度的游泳和弹跳实验，研究了运动后罗氏沼虾的行为、能量来源和相关代谢酶活性。游泳强度通过在特定时间内设置不同的水流速度来确定，对照、低、中、高强度的水流速度分别为0 (自由运动)、5 (200 min)、10 (200 min)和15 cm/s (游泳至疲劳)。弹跳强度通过在特定时间内设置不同触碰频率来确定，对照、低、中、高强度的触碰频率分别为0 (自由运动)、0.033 (5 min)、0.050 (5 min)和0.067 Hz (弹跳至疲劳)。结果显示，罗氏沼虾各运动组游泳足和尾肢的最大摆动频率和最大摆动幅度均显著高于对照组。各运动强度组肌肉蛋白质含量与对照组之间无显著差异，肌肉糖原含量均显著小于对照组，低强度游泳组肌肉甘油三酯含量小于对照组。中、高强度游泳组游泳足肌肉乳酸脱氢酶(LDH)活性和乳酸含量显著高于对照组，低强度游泳组游泳足肌肉丙酮酸脱氢酶、苹果酸脱氢酶和脂肪酶活性显著高于对照组。无论弹跳强度高低，罗氏沼虾腹部肌肉LDH酶活性和乳酸含量均显著高于对照组。研究表明，罗氏沼虾通过...

| Abstract: | To explore the behavioral characteristics of locomotion and their relationships with muscle energy metabolism of Macrobrachium rosenbergii, the experiments of swimming and tail-flipping with four intensities (control, low, medium and high) were conducted. The behavior, energy sources and related metabolic enzyme activities of M. rosenbergii were determined after locomotion. The swimming intensities were obtained by setting different water velocities in a specific time interval. The water velocities of control, low, medium and high intensity swimming were 0 (voluntary locomotion), 5 (200 min), 10 (200 min) and 15 (swimming until fatigue) cm/s respectively. The tail-flipping intensities were determined by setting different touch frequencies in a specific time interval. The touch frequencies of control, low, medium and high intensity swimming were 0 (voluntary locomotion), 0.033 (5 min), 0.050 (5 min) and 0.067 (tail-flipping until fatigue) Hz respectively. Results showed that the maximum beat frequency (fmax) and maximum beat amplitude (Amax) of pleopods and uropods were significantly higher in each locomotor group than those in the control group. There were no significant differences in muscle protein contents among different locomotor groups. The contents of muscle glycogen were significantly decreased in each locomotor group compared with that in the control group. The lowest contents of triglyceride in pleopods muscles were observed in the low-intensity swimming group. The activities of lactate dehydrogenase (LDH) and lactate contents in pleopods muscles were significant elevated in medium and high intensity swimming groups compared with those of control group. The activities of pyruvate dehydrogenase, malate dehydrogenase and lipase in pleopods muscles were significantly increased in low-intensity swimming group compared with that of control group. The LDH activities and lactate contents of abdominal muscles were significantly higher in each tail-flipping group than that of control group. Our findings indicate that the energies of locomotion are obtained by increasing the relies on muscles energy metabolism in M. rosenbergii. The energy metabolism pathways of swimming vary according to swimming intensities. Tail-flipping is powered by anaerobic metabolism. |
