| 中文摘要: |
| 为了研究日本沼虾瞬时耗氧速率在不同温度下的变化规律及其与溶氧水平的关系，以日本沼虾为试验
对象，设4 个温度梯度(15、20、25、30益），采用密闭呼吸室法，求得各温度下试验虾耗氧量随时间的变化状况。结果表
明，日本沼虾的瞬时耗氧速率随时间的增加而降低，且呈良好的乘幂函数增长关系，呼吸类型属于顺应型；在适宜溶
解氧量及温度范围内，瞬时耗氧速率均随相应溶解氧含量和温度的升高而增加，且呈良好的线性相关关系。 |

| To research the change rules of instantaneous rate of oxygen of Macrobrachium nipponense at different
temperatures and the correlation between it and dissolved oxygen, using M. nipponense with average body length of 5.59(依
0.05) cm and average body weight of 4.09 (依0.06) g as testing shrimps, 4 temperature gradients of 15益, 20益, 25益, 30益
were set up to conduct the closed respiratory test, to get varying condition of oxygen consumption of M. nipponense with
time increasing. The results indicated that instantaneous rate of oxygen consumption of M. nipponense decreased with time
increasing, and they had good power function relation. The respiratory type of M. nipponense belonged to compliance. In
suitable dissolved oxygen and temperature range, instantaneous rate of oxygen consumption of M. nipponense increased
with dissolved oxygen and temperature increasing, and it showed a good linear correlation with both dissolved oxygen and
temperature. |
