| 摘 要： | 南方鲇（Silurus meridionalis Chen）和瓦氏黄颡鱼（Pelteobag vachelli Richardson）均为我国特有的暖水性鱼类，但急性温度变化是鱼类在商品运输、养殖生产甚至自然生活过程中可能遭遇到的胁迫。监测鱼类在急性温度胁迫后的耗氧率（VO2）和呼吸频率（Vf）变化有助于评价急性温度变化对鱼类胁迫的影响。

| Abstract: | The objective of the study was to explore the effeot of acute low temperature stress on VO2 and Vf of Silurus meridionalis and Pelteobag vachelli after 10 minutes cold water bath witll different temperature.Tee investigation was operated under the temperature of 24 ℃. It was found that the VO2 and Vf of Silurus meridionalis after 6 and 0 ℃ stress showed a decrease-increase-decrease trend while other groups showed a rapid increase then slowly recovery trend.The VO2 ,and Vf of Pelteobag vachelli after 0 ℃ stress showed a decrease-increase-decrease trend while other grcops showed an increase then slowly recovery process. It was suggested that Pelteobag vachelli was more adaptive to acute cold stress.but it cost more energy adapting to cold stress compared to Silurus meridionalis. |
