摘　　要：研究了在水温为28℃,盐度为5.5的条件下,凡纳滨对虾瞬时耗氧速率和体长及溶解氧水平的关系。共测定了6种不同体长(1.36-10.84 cm)凡纳滨对虾的瞬时耗氧速率。结果表明,凡纳滨对虾的瞬时耗氧速率V随时间的增加而降低,两者之间存有良好的线性相关,呼吸类型属于顺应型;V随水环境中溶解氧含量DO升高而增加,V与DO之间呈良好的线性相关;V随虾体长的增长而降低,两者之间也具有良好的线性关系。The correlation between instantaneous rate of oxygen consumption of Penaeus vannamei and body length as well as dissolved oxygen level was studied at water temperature 28 ℃ and salinity 5.5. Instantaneous rate of oxygen consumption of Penaeus vannamei with different body length （ 1. 36 - 10. 84 cm ） was determined. The results were as follows： Instantaneous rate of oxygen consumption [ V, mg/（ g · h）] of Penaeus vannamei decreased with increasing time （t, h） and body length （L, cm） as well as decreasing dissolved oxygen content （DO, mg/L）. There is correlation between V and t. The respiration type of Penaeus vannamei is the compliance type. There are linear correlations between V and DO, V and body length respectively.
