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℃),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（± 0.05） cm and average body weight of 4.09 （±0.06） g as testing shrimps, 4 temperature gradients of 15℃, 20℃, 25℃, 30℃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.
