以太湖秀丽白虾(Exopalaemon modestus)人工驯养子代为实验样本,实验共设置6个体质量梯度及7个温度梯度,样本体质量范围为(0.12±0.01)～(1.93±0.05)g,实验温度范围为12℃～30℃,研究了体质量及水温对耗氧率和排氨率的影响。结果表明:秀丽白虾耗氧率变幅为0.1497～0.9053mg·g-1·h-1,均值为0.3901mg·g-1·h-1;排氨率变幅为0.0165～0.0866mg·g-1·h-1,均值为0.0379mg·g-1·h-1。体质量、水温及两者的交互效应均对耗氧率和排氨率具有极显著的影响(P<0.01)。体质量与耗氧率和排氨率之间的回归关系分别符合幂函数方程Ro=0.3114W-0.2414(r=-0.436)和Rn=0.0307W-0.3007(r=-0.653);水温与耗氧率和排氨率之间的回归关系分别符合指数方程Ro=0.0711e0.0749t(r=0.877)和Rn=0.0113e0.0530t(r=0.747);体质量、水温与耗氧率及排氨率的二元回归方程分别为Ro=0.028T-0.147W-0.053(r=0.948)和Rn=0.002T-0.017W+0.013(r=0.922)。耗氧率和排氨率Q10变幅分别为1.17～4.20和1.15～2.29,均值分别为2.10和1.64。在实验温度范围内,氧氮比均随着水温的上升而增大,变幅为7.42～13.62,均值为10.04。秀丽白虾在低温阶段(12℃～18℃)主要以蛋白质为供能物质,在高温阶段(21℃～30℃)对脂肪的利用有所增加,中等规格个体的脂肪代谢率最高。
Six offspring of domesticated Exopalaemon modestus were used as experimental samples. Six body mass gradients and seven temperature gradients were set up in this experiment. The body mass range was (0.12 ± 0.01) ~ (1.93 ± 0.05) g, and the experimental temperature range For 12 ℃ ~ 30 ℃, the effects of body weight and water temperature on oxygen consumption rate and ammonia excretion rate were studied. The results showed that the oxygen consumption rate of white shrimp decreased from 0.1497 to 0.9053 mg · g-1 · h-1 with a mean value of 0.3901 mg · g-1 · h-1, and the ammonia removal rate ranged from 0.0165 to 0.0866 mg · g -1 · h-1, with an average of 0.0379 mg · g-1 · h-1. Body mass, water temperature and the interaction between the two have a very significant impact on oxygen consumption rate and ammonia excretion rate (P <0.01). The regression relationship between body mass, oxygen consumption rate and ammonia excretion rate was in accordance with the power function equation Ro = 0.3114W-0.2414 (r = -0.436) and Rn = 0.0307W-0.3007 (r = -0.653) The regression relationship between rate and ammonia excretion rate was in accordance with the exponential equation Ro = 0.0711e0.0749t (r = 0.877) and Rn = 0.0113e0.0530t (r = 0.747) respectively. The body weight, water temperature and oxygen consumption rate and ammonia excretion rate The binary regression equations were Ro = 0.028T-0.147W-0.053 (r = 0.948) and Rn = 0.002T-0.017W + 0.013 (r = 0.922) respectively. Oxygen consumption rate and ammonia excretion rate Q10 amplitude were 1.17 ~ 4.20 and 1.15 ~ 2.29, mean values were 2.10 and 1.64. In the experimental temperature range, the ratio of oxygen to nitrogen increased with the increase of water temperature, ranging from 7.42 to 13.62 with a mean of 10.04. In the low temperature stage (12 ℃ ~ 18 ℃), the white shrimp mainly uses protein as the energy supply substance, and increases the utilization of fat in the high temperature stage (21 ℃ ~ 30 ℃), and the fat metabolism rate of the medium size individual is the highest.
